Cisco IOS Telephony Service, Version 2.02
Chapter 5 Command Reference
pattern ext-to-ext busy (vm-integration)
Usage Guidelines The pattern ext-to-ext busy 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 busy from a Cisco 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 that identify the
extension number of the calling IP phone.
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 a local call forwarded on busy to the voice-mail
system:
Router(config) vm-integration
Router(config-vm-integration) pattern ext-to-ext busy 7 FDN * CGN *
