DETAILED STEPS
Command Purpose
Step 1
vm-integration
Example:
Router(config) vm-integration
Enters voice-mail integration mode and enables voice-mail
integration with DTMF and analog voice-mail system.
Step 2
pattern direct tag1 {CGN | CDN | FDN} [tag2
{CGN | CDN | FDN}] [tag3 {CGN | CDN | FDN}]
[last-tag]
Example:
Router(config-vm-int) pattern direct 2 CGN *
Configures the DTMF digit pattern forwarding necessary to
activate the voice-mail system when the user presses the
messages button on the phone.
• The tag attribute is an alphanumeric string fewer than
four DTMF digits in length. The alphanumeric string
consists of a combination of four letters (A, B, C, and D),
two symbols (* and #), and ten digits (0 to 9). The tag
numbers match the numbers defined in the voice-mail
system’s integration file, immediately preceding either
the number of the calling party, the number of the called
party, or a forwarding number. The Cisco SRS Telephony
router supports a maximum of four tags.
• The keywords—CGN, CDN, and FDN—configure the
type of call information sent to the voice-mail system,
such as calling number (CGN), called number (CDN), or
forwarding number (FDN).
Step 3
pattern ext-to-ext busy tag1 {CGN | CDN |
FDN} [tag2 {CGN | CDN | FDN}] [tag3 {CGN |
CDN | FDN}] [last-tag]
Example:
Router(config-vm-integration) pattern
ext-to-ext busy 7 FDN * CGN *
Configures the DTMF digit pattern forwarding necessary to
activate the voice-mail system once an internal extension
attempts to connect to a busy extension and the call is
forwarded to voice mail.
Step 4
pattern ext-to-ext no-answer tag1 {CGN | CDN
| FDN} [tag2 {CGN | CDN | FDN}] [tag3 {CGN |
CDN | FDN}] [last-tag]
Example:
Router(config-vm-integration) pattern
ext-to-ext no-answer 5 FDN * CGN *
Configures the DTMF digit pattern forwarding necessary to
activate the voice-mail system once an internal extension
fails to connect to an extension and the call is forwarded to
voice mail.
