Allow CMA endpoints to continue to operate in the event of the CUCM cluster being inaccessible. This would be a very important feature when customers have to decide between whether to migrate to CMS or not. It is important to know that an SRST option exists when using CMA. Seeing as Cisco Meeting Server is now the recommended approach by Cisco for TP on premise, it is likely that CMA will be the nature choice for softphone over time. If so then it should also be able to operate during a network failure, much like Jabber (even if only audio is supported at this point in time). This will probably require the SRST to run an XMPP server alongside the SIP registrar.Your thoughts?
