A dedicated dial peer is required to facilitate communication between Cisco CallManager Express and Cisco Unity Express. The destination-pattern under the dial peer assigns a set of phone numbers dedicated to applications such as Cisco Unity Express. One thing that you need to consider is that the voicemail number must be within the destination-pattern range of the dial peer, and the ephone-dns must be configured for call forwarding to the voicemail number which triggers the use of the dial peer. The Cisco Unity Express dial peer must use Session Initiation Protocol (SIP) for call sessions and for the translation of dual tone multifrequency (DTMF) tones into SIP notify messages. A voice activity detection (VAD) must be switched off and a codec must be designated.
Enter the command enable in order to enter the EXEC mode.
Enter the command configure terminal in order to enter the configuration mode.
Enter the command dial-peer voice tag voip in order to define a dial peer with a method of voice encapsulation.
Router(config)#dial-peer voice 2 voip
Enter the command destination-pattern string in order to specify the prefix or the full E.164 number to be used for the dial peer.
Enter the command session protocol sipv2 in order to specify SIP as the session protocol for calls between host Cisco CallManager Express router and Cisco Unity Express module.
Router(config-dial-peer)#session protocol sipv2
Enter the command session target ipv4:destination-ip address in order to designate a network-specific address to receive calls from a voice over IP dial peer.
SIP traces provide key information in troubleshooting SIP Trunks, SIP
endpoints and other SIP related issues. Even though these traces are in
clear text, these texts can be gibberish unless you understand fully
what they mean. This document attempts to br...
