Dear All :
thank you very much for this fantastic Support Community
i have the following case: two sites : headquarter with CCUM and branch site with voice gateway cisco router 3845 configured as SSRT mode as following :
- on call manager(10.50.3.11) the SRST congiguration is done to refer to the branch voice gateway
10.51.3.15 port:2000
- on the branch voice gateway(10.51.3.15), the configuration is :
dial-peer voice 10 voip
description ---- Accept & Send CCM2
destination-pattern 1.....
session target ipv4:10.50.3.12
voice-class codec 1
voice-class h323 1

i am using the dial plan 1..... and when the two WAN links are down between the two sites the network configuration on each cisco ip phone in the branch shows SRST as third call manager but the ip phones inside that branch can't call each other ?did i miss any step ,
i think my dial peer(10,11) is not working on the SRST mode since they are still referring to the call manager
please help

You only have dial peers to CUCM, and I don't see any PSTN dial peers. Can you post the entire "show run" so we can determine which protocol you use MGCP vs SIP vs H323 and type of PSTN trunks you have?

Looks like you have many POTS dial peers pointing to PSTN. Replicate the issue and provide "debug voice ccapi inout" and "debug voice dialpeer"

Dear Chris:
when fallback ,i don't want anything to go over PSTN ,
i want just the internal ip phones in the branch to call each other in that branch ...
hope that understood

You could use after-hours block pattern feature with 24x7 option:
