unable to call in after SRST was active

Unanswered Question
Mar 19th, 2009


I'm running CUCM7.0 and on remote offices are Voicegateways (IOS 12.4(22)T) with SRST.

When WAN is down, the phones are working correctly in SRST mode, but when the WAN comes backup and the phones are registered back to CUCM. it isn't possible to call in. I'm hearing a busy tone. As it generates a dial-peer in SRST mode for the directory numbers, the auto-generated dial-peers has a higher match, than the dial-peer I configured. So I have to delete all the ephone-dn that it will be possible to call in. See below the relevant configuration.

dial-peer voice 10 voip

preference 1

destination-pattern 9942[6-9]..

voice-class codec 10

voice-class h323 11

session target ipv4:

dialplan-pattern 2 99427.. extension-length 4

dialplan-pattern 3 99428.. extension-length 4

dialplan-pattern 4 99429.. extension-length 4

hunt-group logout HLog

moh music-on-hold.au

multicast moh port 2000

web admin system name admin password cisco

Is there a way or a command that it will put the automatic generated dial-peer as second preference?



I have this problem too.

The preference order for the VoIP dial peers to be created has a range from 0 to 10. Default is 0, which is the highest preference.
