Cisco IOS Telephony Service, Version 2.02

Chapter 5 Command Reference

pattern trunk-to-ext no-answer (vm-integration)

Usage Guidelines The pattern trunk-to-ext no-answer command is used to configure the sequence of DTMF digits

passed to a voice-mail system attached to the Cisco IOS Telephony Service router through one or more

voice ports. When a call is routed to the voice-mail system by call forward on no-answer from an IP

phone attached to the Cisco IOS Telephony Service router, the voice-mail system expects to receive a

sequence of digits identifying the mailbox associated with the forwarding phone together with digits

indicating that the call originated from a Public Switched Telephone Network (PSTN) or Voice over IP

(VoIP) caller.

Although it is unlikely that you will use multiple instances of the CGN, CDN, or FDN keyword in a

single command line, it is permissible to do so.

Examples The following example sets the DTMF pattern for call forwarding when an external trunk call reaches

an unanswered extension and the call is forwarded (FDN) to a voice-mail system:

Router(config) vm-integration

Router(config-vm-integration) pattern trunk-to-ext no-answer 4 FDN * CGN *
