We are having problems implementing SRST with telephones using SIP.
SCCP telephones work fine when CCM goes down and register with SRST. Calls are made normally. But SIP phones (we are using 3911 phones) dont register. Navigating throw the phone menu, in configuration-->network-->ccm5 is the name of our SRST GW. The name but not the IP address.
We are running CCM 6.0.1 and our GW is a 2821 (IOS version 12.4-15T3)
We are working without a DNS server in the network.
