Hello - we are looking at adding a SIP Gateway at one of our branches with SRST. The phones will be using SCCP for their protocol. Are there some good documents I could reference as a template for this configuration? Obviously this has to be built in the CM and in the IOS but looking for some type of document that steps you through for what needs to be configured on both ends when adding a branch. Understanding that the dial peers and IP's will change if we decide to add more sites but trying to get to a somewhat cookie cutter cofiguration if that is possible.
first of all advise about your current Call manager version, Voice Gateway model, SRST version you have.
to create SRST for SCCP phones you need to configure telephony-service with SRST mode.

One more question, what kind of GW you have MGCP/SIP/H.323 and what kind of Phones you have, SCCP or SIP?
I am in a similar situation, however I have is MGCP GW with SIP Phones.
