Voice Mail

PSTN-based voice mail enables SPs to offer an alternative to answering machines. This is attractive because subscribers do not need to purchase or operate any additional equipment. Another benefit of network-based voice mail is that voice messaging is still available even if the called party's line is busy. The two main voice mail services available to residential and small-business users are

• Voice messaging—Enables subscribers to store and play recorded greetings and receive, review, and distribute messages from outside users

• Fax messaging—Enables subscribers to receive faxes and view them at a later time
