SIP Question for version 5.0

I have been task to have a few answers about SIP working with SRST.

From reading if CCM fails and SRST is running on the 7912G will not be able to receive incoming calls?

Will we need separate License for CCM and SIP License to support 7912G handsets.

90% of the functionality for SCCP handset for the 7912G has been ported over for SIP what is missing?

What affects is the dual registration for SIP. Basically, SIP has to register with Proxy Server how long will it

take for the handset to register with SRST gateway.

Re: SIP Question for version 5.0

Dual registration allows SIP IP phones to simultaneously register with both their primary and their fallback registrar devices. That is, when a SIP IP phone registers with a Cisco SIP SRST gateway, it simultaneously registers with the main proxy and SIP redirect server for coverage in case of a WAN failure
