DETAILED STEPS
Example
The following example creates access code number 8 for BRI and enables DID on the POTS dial peer:
call-manager-fallback
access-code bri 8 direct-inward-dial
Configuring Interdigit Timeout Values
Configuring interdigit timeout values involves specifying how long, in seconds, all Cisco Unified IP
Phones attached to a Cisco Unified SRST router are to wait after an initial digit or a subsequent digit is
dialed. The timeouts interdigit timer is enabled when a caller enters a digit and is restarted each time
the caller enters subsequent digits until the destination address is identified. If the configured timeout
value is exceeded before the destination address is identified, a tone sounds and the call is terminated.
