Supporting Auto Registration and Auto Assignment of IP Phones

Since its 4.0 version, CME has supported auto-registration of Cisco IP phones by default. This allows IP phones with no ephone configuration in the CME running configuration to automatically register with the CME router. The CME router does not automatically create an ephone entry in the running configuration however, the registered phones can be verified by using the show ephone command, as shown in Example 5.24. Example 5.24 Auto-Registered Ephone Verification Example 5.24 Auto-Registered...

Command Line Interface Versus Graphical User Interface Administrator Management

Traditionally, the CLI has been the preferred method of accessing and configuring Cisco devices, such as Cisco routers and switches. However, Cisco Unity Express runs on a Linux-based operating system, so the CLI of Cisco Unity Express is vastly different from the CLI of traditional Cisco devices. To use the Cisco Unity Express CLI, the administrator must first open a Telnet session (using a Telnet client) to either the hostname or the IP address of the Cisco ISR router that houses Cisco Unity...

Cisco Unity Express Configuration

This section examines the configuration needed for Cisco Unity Express to communicate with Cisco Unified CME. This includes the final Cisco Unity Express CLI configurations and the Cisco Unity Express web initialization.

Configuring Digital Voice Ports

Cisco provides digital T1 and E1 ports in the form of Voice and WAN Interface Cards (VWIC) for routers. These cards offer you the flexibility to configure them for a data connection or a voice connection. Unlike analog interfaces, you must configure digital interfaces before they will operate correctly, because the router does not know the type of network you will be using. As discussed in Chapter 7, Gateway and Trunk Concepts, there are two types of voice network configurations you can use T1...

Understanding the PSTN

Pstn Connections

All the signaling standards and communication methods discussed in the previous section typically focus around the connection to one, massive voice network known as the public switched telephone network (PSTN). If you have ever made a call from a home telephone, you have experienced the results of the traditional telephony network. This network is not unlike many of the data networks of today. Its primary purpose is to establish worldwide pathways allowing people to easily connect, converse,...

Cisco Unity Express Troubleshooting

For Cisco Unity Express to provide voice-mail and auto-attendant services, several pieces need to work together. For this reason, troubleshooting requires that you isolate where the problem exists by asking the questions, What is working and What is not working Asking these questions will help to determine if the root problem exists in one of the following areas Cisco Unity Express configuration This section asks these questions and examines some of the most common issues and troubleshooting...

Private Line Automatic Ringdown

Although not directly related to dial-peer configuration, Private Line Automatic Ringdown (PLAR) configurations rely heavily on existing dial peers to complete a call. Ports configured with PLAR capabilities automatically dial a number as soon as the port detects an off-hook signal. The most obvious use for PLAR configurations is emergency phones in locations such as company elevators or parking garages. The configuration in Example 8.13 designates x1101 (shown in Figure 8.8) as a PLAR...

Configure and Verify 8021Q Trunks

Now that VTP is set, you need to configure the 802.1Q trunks between the switches. Looking back at Figure 3.10, you can see that SwitchA and SwitchB connect on FastEthernet 0 24. To configure trunking on the port, you can use the switchport mode command. This command has a number of parameters, as shown in Example 3.4. Example 3.4 Options Available for the switchport mode Command Example 3.4 Options Available for the switchport mode Command SwitchA(config) interface fastEthernet 0 24...

Where It All Began Analog Connections

Electrical Analog Waveform

In 1877, Thomas Edison created a brilliant device known as a phonograph, shown in Figure 1.1. Figure 1.1 Replica of Edison's Phonograph Figure 1.1 Replica of Edison's Phonograph This device was able to record sounds by pressing a needle into a cylinder covered with tinfoil on a rhythmic basis as a person spoke into a sound collecting horn. The phonograph could then play back this sound by moving the needle at a steady speed back over the indentions made in the tinfoil. This archaic form of...

CCA Telephony Smart Assist Features

Interwoven throughout the CCA tool are several macros that walk you through the process of provisioning devices in an SBCS community. There are macros that assist in deciding several questions What type of roles should a given switch port be assigned. Should spanning tree be turned on or off on this port What should the native VLAN be To someone new to the field of networking, these questions might be a challenge to answer. There are macros for a brand-new wireless SSID and others that help...

Af Power over Ethernet

802.3af PoE is similar to Cisco Inline Power but uses a slightly different detection mecha nism. Rather than using a FLP tone to detect an unpowered PoE device, 802.3af uses a small DC current that is constantly applied to the line. Non-PoE devices are not harmed by this DC current. An 802.3af-capable device will be equipped with a resistor that returns a specific level of resistance to the line. When the switch detects this resistance level, it will know how much power to send to the attached...

Using Cisco AutoQoS

Deploying QoS can be complex (which is why there's a difficult CCVP exam dedicated just to the topic). To help ease the learning curve for QoS, Cisco created a mechanism called AutoQoS, which allows you to enable a variety of QoS mechanisms with very little QoS knowledge. AutoQoS ended up working so well out of the box that many network administrators who have full knowledge of the QoS capabilities and configuration on Cisco devices use it. AutoQoS has moved to this acclaimed status because it...

The Process of Converting Voice to Packets

Harry Nyquist (and many others) created a process that allows equipment to convert analog signals (flowing waveforms) into digital format (1s and 0s). It is important to understand this process as it will guide your configuration of sample sizes, Digital Signal Processor (DSP) resources, and codecs. The origin of the digital conversion process takes us back to the 1920s, a far throw from our VoIP world. The Bell Systems Corporation was trying to find a way to deploy more voice...

Foreign Exchange Station Ports

FXS ports connect to end stations, that is, typical analog devices such as telephones, fax machines, and modems (shown in Figure 8.1). When you are getting ready to configure your FXS voice ports, the best place to start is to find out what voice ports your router is equipped with. You can do this quickly by using the show voice port summary command, as shown in Example 8.1. Example 8.1 Identifying Voice Ports Using show voice port summary Example 8.1 Identifying Voice Ports Using show voice...

Configuring a Voice Network Directory

When most people think of a corporate phone directory, visions of Microsoft Excel spreadsheets e-mailed out monthly come to mind. Isn't there a better way Sure there is Cisco IP phones support a local directory that you can update from the CME router as you are configuring devices. You can enter names under ephone-dn configuration mode either as you are configuring new lines for the organization or separately, after you have configured the lines. These names are used both for building the...

Using Dial Peer Wildcards

As you have seen in the previous few sections, configuring dial peers (and destination patterns) without using wildcards would be extremely time consuming. By far, the most commonly used wildcard is the dot (.), which represents any dialed digit. There are a few other wildcards in addition to this that you will find useful in your configurations. Table 8.3 provides a description for these wildcards. Table 8.3 Wildcards You Can Use with the destination-pattern Command Table 8.3 Wildcards You Can...

Layer 3Multilayer Switching

This final form of inter-VLAN routing uses a router integrated into a switch. This is most often called a Layer 3 or multilayer switch. The concepts are the same as the previous router-on-a-stick design however, the router is now internal to the switch. To facilitate routing within the switch, you must configure switched virtual interfaces (SVIs), as shown in Figure 3.13. SVIs are virtual interfaces supported on Layer 3 switches that route traffic for their assigned VLAN number. As soon as the...

Trunking CME to Other VoIP Systems

As VoIP becomes more popular, businesses will prefer to use interoffice connectivity over data networks rather than the PSTN, due to long-distance cost savings and bandwidth efficiency (VoIP calls can use less bandwidth than traditional PSTN). The singleoffice CME deployment will need to connect with other offices or providers over the VoIP network, as illustrated in Figure 7.6. Cisco Unified Communications Manager System Figure 7.6 Interoffice VoIP Connectivity Cisco Unified Communications...

Configuring POTS Dial Peers

As mentioned previously, you can use POTS dial peers to define reachability information for anything connected to your VoIP network from the traditional telephony world. This includes devices connected to FXO, FXS, E& M, and digital BRI T1 E1 interfaces. Tip If you are connecting to something without an IP address (such as an analog phone, fax machine, PBX, or the PSTN), it is a POTS dial peer. The network in Figure 8.6 demonstrates the configuration of POTS dial peers. Figure 8.6 Dial Peer...

Firmware Load Files

In the section Configuring the Cisco Unified CME Router as a TFTP Server, you saw how to configure the CME router to serve the phone firmware files via TFTP. You must now tell the telephony service which firmware files it should use for the various models of Cisco IP phones it will be supporting. This can be done under the telephony-service configuration mode by using the load command, as shown in Example 4.5. Example 4.5 Specifying Firmware Loads for Cisco IP Phones CME_Voice(config-telephony)...

Configuring Call Pickup

Michael works in the sales department at Widget Things, Inc. Being the newest member to the group, he works the late shift, covering calls from 10 30 a.m. to 7 30 p.m. Around 6 00 p.m., the last coworker leaves and Michael handles all the incoming calls alone. Unfortunately, many of Widget Things' customers have the direct contact information for other sales employees, so a typical evening for Michael consists of running around answering phone calls coming in on the IP phones of the five other...

Configuring Call Park

Typically, when you place a call on hold, you can retrieve the call only from the original phone where you placed the call on hold. Shared-line systems bend the rules a little by allowing you to retrieve the call from any phone with the same shared line assignment. The call park feature takes this one step further by allowing you to retrieve the call from any phone in the organization. Call park parks the caller on hold at an extension rather than on a specific line. Any IP phone that is able...

Practical Scenario 4 Using Translation Profiles

Digit Manipulation Order Operation

The digit manipulation commands discussed thus far allow you to perform minor translations to a number. For example, you could add some digits using the prefix command or ensure digits do or do not get stripped with the forward-digit command. The num-exp command allows you to make the biggest changes of all, but these changes are applied globally to the router, which may not give you the flexibility all situations require. Translation profiles are useful to address these needs. If you find...

Configuring After Hours Call Blocking

In the traditional telephony realm, there have been many recorded incidents of unauthorized phone calls being placed after-hours, when most, if not all, staff has left for the evening. To prevent this, you can implement after-hours call blocking on CME. After-hours call blocking allows you to define ranges of times specified as after-hours intervals. You can then list number patterns that are disallowed during those intervals. If a user places a call during the after-hours time range that...

Installing Unified CME on a Cisco Router

One advantage of Cisco IOS is the ease of installation and upgradability. To perform an IOS installation or upgrade, you can set up a TFTP server on your PC, download IOS from Cisco.com, and then enter a command similar to the following Assuming your TFTP server is working correctly and assigned the IP address 172.16.2.5, the single BIN IOS file would copy over. Once you reboot the router, you would be running the new IOS version. Installing Cisco Unified CME is not quite as simple. Rather than...

Associating Ephones and EphoneDNs

Linking ephones and ephone-dns is probably the most confusing section of the CME configuration because there are so many options. You can assign ephone-dns by using the button command from ephone configuration mode. The basic syntax of this command is as follows button < physical button> < separator> < ephone-dn> Example 5.8 demonstrates the basic use of the button command. Example 5.8 Assigning Ephone-DN 2 to Button 1 on Ephone 1 CME_Voice(config) ephone 1 CME_Voice(config-ephone)...

System Message

As you make configuration changes to the CME router, you may need to reboot the Cisco IP phones managed by the system. You can do this by using either the restart or reset command. The restart command does a warm boot of the IP phone. The phone reboots, but keeps its existing IP address and TFTP configuration files. Because DHCP and TFTP take the most time during IP phone boot process, the phone is able to restart very quickly. Most Cisco IP phones are able to restart in 1 to 2 seconds (you'll...
