SRST dialplan-pattern configuration for incoming and outgoing PSTN calls.

Unanswered Question
May 20th, 2008


I want to configure SRST for one of branch offices.Had a query if "dialplan-pattern" command is sufficient to route incoming PSTN calls to the IP phones in SRST mode.DID range for example is 1234 13XX.Extensions are in range 13XX.Also will the command take care of caller id for outgoing calls?



service alternate default


ccm-manager fallback-mgcp



max-conferences 10 gain -6

transfer-system full-consult

timeouts interdigit 4

ip source-address 10.XX.XX.XX port 2000

max-ephones 240

max-dn 960

dialplan-pattern 1 123413.. extension-length 4 extension-pattern 13..


dial-peer voice 1 pots

incoming called-number .


port 0/0/0:15


dial-peer voice 2 pots

preference 1

destination-pattern 9T


port 0/0/0:15


Let me know if the above configuration is sufficient for SRST and do I need to configure additional translational profile/rule for call routing.Port 0/0/0 is connected to local PSTN.



I have this problem too.

When you have incoming calling translation-profile configured under call-manager-fallback, it will affect all the calls even between IP phones. Then you can remove dialplan-pattern, but append all the digits from translation-rule. If your customer only needs to change the number to the calls to PSTN, you should apply the translation-profile under POTS dial-peer instead of under call-manager-fallback.
