Tip The integrated 10 100BASE-TX switch provides a total of 80W of 802.3af or Cisco prestandard PoE. Administrators should be careful not to...

AA Greetings Prompts

AA greetings, also referred to as AA prompts, are similar to voice-mail greetings, discussed earlier. AA prompts are the messages that a caller hears when they are routed to the AA. As with voice mail, administrators and subscribers with the proper permissions can record and personalize an AA greeting. Unlike a voice mailbox, AA offers the capability to change the greeting based upon the day or a specific time of day. By changing the content of a prompt a business can personalize the AA script...

Many applications exist in addition to the three core applications just mentioned. The following are brief descriptions of the most common additional applications that corporations install in their VoIP environments Cisco Unified MeetingPlace Provides a multimedia conference solution that gives you the capability to conference voice, video, and data into a single conference call. For example, multiple offices could participate in a conference call using IP phones, live video feeds, and instant...

Administration via Telephone System

Administration via Telephone (AVT) gives an administrator an easy way to record custom prompts and to quickly record and enable the AA alternate greeting. When dialing into the AVT, the administrator is prompted to authenticate by entering their extension number and PIN. Once authenticated, the administrator can quickly record and enable an alternate greeting to inform all callers of the current situation. For example, assume that severe weather conditions have forced the business to close. The...

Answers to the Do I Know This Already Quizzes and QA Sections

Both the hardware platform and the license come into play here. The hardware platform has a maximum mailbox limit and the license determines the number of mailboxes that can be configured within the platform's maximum limit. 12. B. Starting a backup is a manual process for Cisco Unity Express. An administrator must log in to the GUI and click the Start Backup button to begin the process. 7. D. While port module port is a valid dial-peer configuration, it is used for routing over a...

Applications Layer

As you move up to the next layer of the Cisco VoIP structure, you encounter the applications that expand the functionality of the voice network in some way. Many applications have already been developed for the Cisco VoIP solution, each of them adding its own special features to the voice network. Three of these application servers stand out as essential applications for many VoIP networks Cisco Unity (voice mail), Interactive Voice Response (IVR) Auto Attendant, and Unified Contact Center.

Assign Ports to VLANs

Now that the VLANs exist, you can assign the necessary ports to each VLAN. Based on the diagram shown earlier in Figure 3.10, the DHCP server will need to join the data VLAN. You will configure FastEthernet 0 20 (connecting to the router Cisco Unified Communications Manager Express CME device) in the next section when you set up routing between VLANs. Example 3.12 assigns FastEthernet 0 10 on SwitchA to VLAN 50. Example 3.12 Assigning Switchport to a VLAN SwitchA configure terminal...

Backup and Restore

Backup and restore options can be found under the Administration menu of the Cisco Unity Express GUI home page. Backing up Cisco Unity Express requires the administrator to configure an FTP server (to use as the target server on which the backup files will be stored) and login credentials to access the FTP server. Note The login credentials supplied must have permission to upload, download, and make directories on the FTP server. After an FTP server has been configured, the administrator must...

Basic Cme Ip Phone Configuration

The anticipation must be killing you You've gone through four chapters on VoIP technology and a phone has yet to ring. That is about to change in this chapter. The foundation system is in place and now the configuration of the Cisco IP phones can begin. Ninety percent of this configuration focuses on two configuration concepts ephone and ephone-dn. These two configurations represent the logical representation of IP phones and directory numbers, respectively. This chapter explains the...

Business Hours Settings

Business hours are determined by a schedule that is configured within Cisco Unity Express. This schedule is broken down into half-hour increments on a Monday through Sunday basis. To operate in the normal business mode, place a check on the half hour time slot. To operate in the closed business mode, clear the check from the time slot. For example, assume that business hours are Monday through Friday from 08 30 to 17 30 (5 30 p.m. in 12-hour time format). For Monday, you would place a check...

Business Class Cisco IP Phones

When working with midsize to enterprise-class network environments, you can expect to commonly encounter the following Cisco IP phones Cisco 7940G, 7941G, 7941G-GE, 7942G, and 7945G. These phones all support two or more lines, larger displays, full-duplex speakerphones, and inline power capabilities.

Calculating Codec Bandwidth Requirements

Before you deploy VoIP over your WAN connections, you'll want to know exactly how much bandwidth the codec you are using will consume. Although it is easy to look at a table of codec bandwidth amounts (such as the earlier Table 7.2), these amounts do not take into account other factors such as sample size, header information, and link-efficiency mechanisms. You can use the following process to calculate the impact voice will have on your network bandwidth Step 1. Determine the audio bandwidth...

Call Processing Layer

The call processing layer is responsible for just that processing calls and all the functionality that goes with them. When a user picks up their phone handset, the call processing layer gets involved to generate a dial tone. Each digit that is dialed is then analyzed and processed. The ring signal is then generated at the remote device and the call is connected. As the users converse, if one of them presses the Transfer button, for example, the call processing layer steps in to process this...

CCNA Voice Exam Updates Version

Over time, reader feedback allows Cisco Press to gauge which topics give our readers the most problems when taking the exams. Additionally, Cisco may make small changes in the breadth of exam topics or in emphasis of certain topics. To assist readers with those topics, the author creates new materials clarifying and expanding upon those troublesome exam topics. As mentioned in the introduction, the additional content about the exam is contained in a PDF document on this book's companion website...

Change password

The recorded name, also called the spoken name, is used by Cisco Unity Express to identify this mailbox to other subscribers on the system. The next step in the self-enrollment process is to record your personal greeting that will be played to callers that are transferred to your voice mail. The final step for self-enrollment is to select a password that you will use to log in to Cisco Unity Express via the TUI. Note Although the tutorial prompts for a password, the PIN is the value that is...

Choosing a Voice Codec

When selecting a voice codec for your network, you should ask the following questions regarding the codec Is the codec supported on all VoIP devices in my network How many Digital Signal Processor (DSP) resources does it take to code audio using the codec Does the codec meet satisfactory quality levels for my network for all audio types How much bandwidth does the codec consume How does the codec handle packet loss Does the codec support multiple sample sizes What are the ramifications of using...

The Cisco 7931G provides the following key features Built-in switch Built-in 10 100 Ethernet switch for co-locating other network devices Inline power support Can receive...

Cisco 7985G

The Cisco 7985G model represents the first integrated video and VoIP phone solution from Cisco. Although video could have been integrated into the 797X series, the natural sitting posture of most people would give an unflattering up the nose view when using VoIP capabilities. To remedy this, the Cisco 7985G places the camera and video screen at eye level, as shown in Figure 2.8. Courtesy of Cisco Systems, Inc. Unauthorized use not permitted. The Cisco 7921G phone brings 802.11 wireless and VoIP...

Cisco Catalyst Switch PoE

If you were to create an Ethernet cable (Category 5 or 6), you would find that there are eight wires (four pairs of wires) to crimp into an RJ-45 connector on each end of the connection. Further study reveals that only four of the wires are used to transmit data. The other four remain unused and idle until now. The terms inline power and Power over Ethernet (PoE) describe two methods you can use to send electricity over the unused Ethernet wires to power a connected device. There is now a...

Cisco Configuration Assistant

CCA, an application that is downloadable from Cisco.com free of charge, is the tool you use to configure, manage, and maintain the SBCS suite. In Chapter 11 you were introduced to the Smart Business Communications System. In that introduction, the UC520 was likened to the human heart. As the central part of the suite, the UC520 is the heart of the SBCS platform. All voice and data traffic throughout the suite is processed and pumped out to the platform's peripherals through the UC520. If the...

Cisco Configuration Assistant Tool

Cisco simplified the management of the SBCS suite by designing a management interface that is powerful, intuitive, and complete. The Cisco Configuration Assistant (CCA) is a GUI configuration tool that simplifies the customization of any preconfigured system parameters that cannot be left to system defaults. The CCA is aware of the components that make up the SBCS suite and will poll a new system to determine which of the components have been applied to a particular setup. The CCA facilitates...

Cisco Inline Power

Cisco Inline Power is often called Cisco prestandard PoE. Because Cisco was one of the early VoIP vendors (Cisco prestandard PoE was created in 2000), many IP phones were purchased before the 802.3af PoE standard was created and implemented in Cisco devices. Whereas an organization typically swaps and upgrades PCs every 3 to 5 years, IP phones can survive the technology curve much longer. Because of this, you will run into many Cisco prestandard PoE devices for years to come. To support these...

Cisco Unified Communications Manager

When moving from Cisco Unified Communications Manager Business Edition to a full CCM solution, you are primarily gaining two key benefits redundancy and scalability. The full Cisco Unified Communications Manager network solution can scale to virtually any size and allows you to implement multiple redundant servers that can support IP phones and applications should any of your primary call processing servers fail. Table 2.3 compares each of these call processing products. Table 2.3 Cisco Call...

Cisco Unified Communications Manager Business Edition

As a business continues to grow beyond the capacity of Cisco Unified CME, the next step in the journey to a full Cisco Unified Communications Manager (CCM) solution is Cisco Unified Communications Manager Business Edition. Moving to this platform means you have now moved away from a router-integrated solution into a dedicated server platform. One example of these dedicated servers is the Cisco Media Convergence Server (MCS) 7835, shown in Figure 2.3. Figure 2.3 Cisco Media Convergence Server...

Cisco Unified Communications Manager Express

When businesses outgrow the 48-phone limitation of the UC500 system, the next step is to move into a Cisco Unified CME system, which is scalable to 250 IP phones, depending on the router platform on which you choose to run CME. Table 2.2 breaks down current CME platform limitations.

Cisco Unity Products

Cisco has designed the Cisco Unity product line to encompass everything dealing with messaging. Whereas traditional phone systems are geared to deliver messages to telephone handsets, Cisco Unity allows you to deliver messages to a variety of clients. This allows VoIP network users to unify (thus the name) all messaging into a single point of access. For example, fax messages, voice mail, and e-mail can all be delivered to a single inbox. The Cisco Unity product line comes in three different...

CME Configuration

Another benefit of the Cisco Unity Express GUI is the capability to configure most CME CLI features. To add a phone in CME, you must first use the CLI to configure an e-phone next, you need to add and assign an ephone-dn to the configured e-phone. All this work is CLI based. An administrator can now perform these same tasks with the common interface into CME provided by the Cisco Unity Express GUI. The CME configuration options are located under the Configure and System menus of the Cisco Unity...

The SBCS suite delivers the power of Unified Communications to the small business with several key components, as listed and described in Table 11.2. . Table 11.2 Smart Business Communications System Suite Components UC500 Series for Small Business (UC520) Suite's central point of connection, IP routing, security...

Configure and Verify VTP

Rather than start with VTP configuration, you first need to understand the command to verify VTP. This is necessary because you never want to introduce into the network a switch that has an existing VTP configuration (otherwise, the existing VLAN database of your organization could be overwritten, causing a massive network outage). The command to verify VTP operation is show vtp status, which is shown in Example 3.1 on SwitchA. Example 3.1 The show vtp status Output Example 3.1 The show vtp...

Configure Routing Between VLANs

All the pieces of the puzzle are in place, with the exception of inter-VLAN routing. With the current setup, all the data devices on VLAN 50 will be able to reach each other, but cannot reach other networks. Likewise, the IP phones will be able to communicate directly, but they cannot reach any other networks or the CME router. As a result, the IP phones will continue to boot cycle endlessly. To set up inter-VLAN routing, there are three possible designs Separate router ports configured per...

Configuring a Router Based DHCP Server

We have currently made it up to Step 4 in the preceding IP phone boot process. The phones in our network now need to receive IP address and TFTP server information. In the network design scenario used in this chapter, we are using the WAN branch router as the DHCP server. Using a router as a DHCP server is a somewhat common practice in some small and midsized networks. Once you move into larger organizations, DHCP services are typically centralized onto server platforms. Either DHCP option is...

Configuring Analog Voice Ports

Similar to Ethernet, when you connect a cable to an analog voice port on a router, it just works (provided there is a signal coming from the other end). The router receives the electrical signals from the line and processes them normally. In addition to normal call processing, there are a few settings you can tune on each interface type to change the way it operates with the other end of the connection. This section describes configuration options for Foreign Exchange Station (FXS) ports and...

Configuring and Maintaining the UC500 Series for Voice

Armed with the knowledge of how IP phones are configured in Cisco Unified CME from Chapter 5 and having been introduced to the UC500 Series for Small Business in Chapter 11, you are now going to delve into the implementation, configuration, and maintenance of the voice components of the UC520 chassis. Chapter 11 introduced you to the SBCS suite and the fact that it was put together with simplicity in mind. This chapter walks you through the simple menus of the Cisco Configuration Assistant...

Configuring and Verifying Gateways and Trunks

Connecting a voice gateway to another voice network is similar to connecting a router to a data network plugging in the cable is the smallest part of the configuration. When the physical connections are in place, let the configuring begin. Instead of routing tables, voice gateways build the logical dial plan through a system of dial peers. This chapter explores the configuration and testing of dial peers in a voice environment. A voice network is only as good as the foundation infrastructure....

Configuring Call Forwarding

There are two methods used to forward calls to a different destination from the IP phone (the user's method) and from the Cisco IOS CLI (the administrator's method). This section describes both methods and also provides an overview of the call-forward pattern command. To forward calls from the IP phone, simply press the CFwdAll softkey button, shown in Figure 6.4. The IP phone will beep twice and allow you to enter a number. Enter the number to which all calls on the IP phone will forward, and...

Configuring Call Transfer

Transferring calls represents another common function in voice networks. To transfer a call, hit the Trnsfer softkey while on an active call. (Note that this is not a typo Trnsfer without the a is correct.) When you do, you will hear another dial tone, at which point you can dial the phone number to which you want to transfer your active call. What happens from there depends on the transfer method configured on the CME router. There are two transfer methods available Consult Consult transfer...

Configuring CDRs and Call Accounting

Who made that call That question could arise for many reasons. Perhaps the entire police and fire departments arrive at the front door of your company because of an emergency call originating from your business. Perhaps management is reviewing the recent long distance bill and came across an international call to Aruba that was four hours in length. Whatever the reason, you can find the answer by looking through the archived Call Detail Records (CDRs), as long as you have configured the CME...

Configuring Intercom

Intercom configurations are common in traditional phone systems. This feature allows an administrative assistant and executive to work closely together by having a speakerphone tether between them. Technically, the way intercom deployments work is through a speed-dial and auto-answer speed-dial configuration. If the administrative assistant presses the button configured as an intercom, it speed dials the executive's phone, which auto-answers the call on muted speakerphone. To establish two-way...

Configuring Music on Hold

What voice network would be complete without the sound of music coming through handsets on hold everywhere CME has the ability to stream Music on Hold (MoH) from specified WAV or AU audio files that you copy to the flash memory of the router. CME can stream this audio either in multiple unicast streams (which is more resource intensive) or in a single multicast stream (which is less resource intensive, but requires a multicast network configuration). In addition, CME can stream the MoH using...

Configuring Physical Voice Port Characteristics

Before you can dive fully into the configuration of dial plans using dial peers, you first have to think about the physical characteristics of the voice ports on the router. Obviously, the voice ports plug into a cable, which eventually connects to a far-end device. Beyond that, there are a few additional settings on the router that you can tune to allow the voice ports to operate exactly to your specification. This section divides the discussion of these configurations into analog and digital...

Configuring the Cisco Unified CME System Level Functions

Now that the Cisco Unified CME router is serving up the correct firmware files, you can get into the configuration of the CME system itself. You can configure just about all of the CME settings from the telephony-service configuration mode, which you access simply by entering telephony-service from global configuration mode. Four key system-level functions need to be specified in order for the CME router to begin supporting IP phones Maximum phones and directory numbers Source IP address...

Configuring VoIP Dial Peers

Looking at the scenario shown in Figure 8.7, the POTS dial peers now provide connectivity to the legacy voice equipment. However, CME_A and ROUTER_B are divided by an IP WAN connection that the legacy voice equipment must cross to achieve end-to-end communication. Figure 8.7 Dial Peer Configuration Scenario Figure 8.7 Dial Peer Configuration Scenario To accomplish this connectivity, you must use VoIP dial peers, because you are crossing an IP-based network. Example 8.11 configures the necessary...

Connecting and Powering Cisco IP Phones

Before we can get to the point of plugging in phones and having happy users placing and receiving calls, we must first lay the foundational infrastructure of the network. This includes technologies such as Power over Ethernet, voice VLANs, and DHCP. The network diagram shown in Figure 3.1 represents the placement of these technologies. As you read through this chapter, each section will act as a building block to reach this goal. The first item that must be in place is power for the Cisco IP...

Create VLANs

After you have configured the trunks, you can move on to creating VLANs. At this point, VTP should be operational between SwitchA and SwitchB (VTP will move into operation once it has a valid trunk connection between switches). As you configure VLANs on SwitchA, they should automatically replicate to SwitchB. The syntax to create VLANs is simple move into global configuration mode and enter vlan < vlan number> . You will then be taken into VLAN configuration mode, where you can assign a...

Creating Communities

Now, with a preliminary understanding of the concept of a CCA community, you are poised to create your own. Creating your own community will go a long way toward cementing your understanding of the concept and its parameters. To create a new CCA community, you must seed the new community discovery process. In that process, you need to decide how you will detect the members of your new CCA community. The default method involves selecting a central seed device, usually your UC520, and using its...

Default Auto Attendant Scripts

A call is routed from Cisco Unified CME or Cisco Unified Communications Manager to the Cisco Unity Express AA. When the call arrives at the Cisco Unity Express AA, a Cisco Unity Express script is activated. This script determines the treatment the caller will receive. For example, assume that a caller dials 404.555.1050 and is routed to a Cisco Unity Express AA. The caller hears Welcome to the automated attendant. To enter the phone number of the person you are trying to reach, press 1. To...

Deploying the SBCS Suite as a WAN Branch Office

Although this type of SBCS deployment is likely to be uncommon, it is mentioned here to point out a few design caveats that should be taken into consideration when integrating the suite with a larger data infrastructure. The UC520 is engineered to use an upstream Ethernet connection, typical in a DSL or cable modem Internet service provider scenario. This connection is via the WAN port (refer to item 8 in Figure 11.1). If this office is a branch office and the overall system design requires the...

Deploying the SBCS Suite for Eight Users

Deploying the SBCS suite for eight or fewer users is extremely simple. Because the heart of the system, the UC520, already has eight built-in PoE switch ports, an expansion switch from the CE520 family of switches is typically not needed. In this very small use case, the single integrated wireless AP will generally be sufficient for wireless needs. The 8- and 16-user models of the UC520 come in a desktop form factor, so if the system will be installed in a standard 19-inch rack, a special...

Deploying the SBCS Suite for Up to 16 Users

Deploying the SBCS suite for up to 16 users is typically very much like the eight-user case with the exception of licensing and the requirement for additional PoE ports. Additional PoE ports are supplied by adding a Catalyst Express CE520-8PC to an appropriately licensed UC520 chassis as depicted in Figure 11.5. The AP integrated into the UC520 is typically sufficient in this small design, but if additional access points are required because of data throughput or wireless propagation issues,...

Deploying the SBCS Suite for Up to 48 Users

Although no more difficult than deploying the SBCS suite for 8 or 16 users, the design for a system that supports up to 48 users is a bit different. As is the case in the deployment of every SBCS design, the UC520 is the heart of the design. The UC520 chassis that supports 32 or 48 users comes in a rack-mount form factor and does not come with an integrated wireless option. Typically, PSTN connectivity for an office of this size will be a channelized T1 E1 however, high-density FXO models of...

Determine the time of day

If open, play a prompt allowing the caller to choose which subscriber to be transferred to. Press 1 to talk to John Smith. Press 2 to talk to Jane Doe. If closed, transfer the caller to an off-premises number. This can be accomplished by using Cisco Unity Express Editor to create a custom script, with each task described previously performed by software steps in the script. Whereas this example demonstrates a very basic script, Cisco Unity Express Editor has the capability to create very...

DHCP Services

Once the IP phone receives its voice VLAN information, it begins sending DHCP requests. The configuration in Example 5.2 allows a Cisco router to become a DHCP server for the voice VLAN and deliver the needed IP address information to the IP phones. Example 5.2 Configuring a DHCP Scope on a Router ROUTER(config) ip dhcp pool VOICE_SCOPE ROUTER(dhcp-config) network 172.16.1.0 255.255.255.0 ROUTER(dhcp-config) default-router 172.16.1.1 ROUTER(dhcp-config) option 150 172.16.1.1 ROUTER(dhcp-config)...

Dial by Name and Dial by Extension

When a caller is redirected to the AA, they are given the option to be transferred to a subscriber. To identify the desired subscriber, the caller can choose to spell the subscriber's name or enter the subscriber's extension. With the spell-by-name function, the administrator has the option to require callers to use either last name first or first name first. For example, a search for John Smith using the last-name-first configuration would result in the caller entering Smith John on the phone...

Enabling the Cme Gui

Cisco provides a graphical user interface (GUI) that allows you to manage some of the CME basic functions through a web interface. These basic functions include configuring and managing ephones, ephone-dns, some system and voice-mail functions, and reports. Note After being in the Cisco world for some time, you will definitely get the feeling that real Cisco techs use the command-line interface (CLI). Seeing the CME GUI will only reinforce that feeling although it does enable you to configure...

Endpoints Layer

The final layer of the Cisco VoIP structure contains the endpoints of the system. This is, most likely, the only layer that your end users will interact with directly. Now, keep this in mind VoIP allows you to take audio and convert it into IP-based packets. This means that any device connecting to a network could potentially be a VoIP endpoint. For example, an instant messenger client or even a website could be considered a VoIP endpoint. So, rather than digress into the many different...

Ensuring the Foundation

Chapter 3, Connecting IP Phones to the LAN Infrastructure, and Chapter 4, Installing Cisco Unified Communications Manager Express, put configurations in place that are key to a working CME system. It would be wise to take a high-level review of those concepts before jumping straight into the configuration of the IP phones. Just about all the concepts discussed so far focus on the boot process of the Cisco IP phone. The following list outlines the Cisco IP phone boot process, which is...

Foreign Exchange Office Ports

FXO ports act as a trunk to the PSTN central office (CO) or PBX systems, as shown in FXO ports use many of the same commands as FXS cards, such as signal to set loop start or ground start signaling, and station-id to set caller ID information. There are two additional commands that are of note The dial-type < dtmf pulse> command allows you to choose to use dual-tone multifre-quency (DTMF) or pulse dialing. Yes, there are still some areas of the world that require the use of pulse dialing...

Gateway and Trunk Concepts

At this point, you now have the knowledge to assemble, configure, and operate a VoIP network internal to your organization. At some point, this voice network will have to grow beyond itself and connect to other voice networks, perhaps most importantly the PSTN. This chapter is dedicated to describing the methods you can use to connect your VoIP network to other networks. The chapter begins by discussing the process of converting spoken audio into packets. From there, this chapter discusses the...

General Delivery Mailboxes

Unlike the subscriber mailbox, a general delivery mailbox (GDM) is assigned to a group of people. For example, a GDM is created and assigned to the customer service department. The delivery of a message to the GDM is similar to the delivery of a message to a subscriber mailbox. An extension number associated with the GDM is configured to forward to Cisco Unity Express if this extension is busy or is not answered. A caller is redirected to the GDM greeting. This greeting may state, Thank you for...

Generated Configuration Files

The last area of configuration focuses on generating configuration files for the Cisco IP phones. Think back to the IP phone boot process once the IP phone gets an IP address and TFTP server information from the DHCP server, it then attempts to contact the TFTP server to download its configuration file and firmware. Up to this point, there has been no discussion about that configuration file. So what is it The IP phone uses its configuration file to determine which IP address to use when...
