Hi guys. we have cisco sx20, sx60, c40, c90 codecs in infr. Right now they are registered on VCS and managed by TMS . Is it possible to register them to both system VCS (h323) and CUCM (sip), kinda a dual registration so they will have both registration.
Although it is possible that you can do that, it's not supported by Cisco and they may tell you to remove one of the registrations if you contact TAC for support.
When the endpoint reboots and registers with CUCM, H323 will become disabled and is by design, dual registration is mentioned in the TC7 Release Notes:
When using CUCM provisioning, the endpoint cannot register to a VCS (SIP or H.323) at the same time. This use-case is not supported by Cisco. When CUCM provisioning is active, H.323 mode is disabled. Cisco recommends TelePresence customers to migrate from H.323 to SIP.
SIP traces provide key information in troubleshooting SIP Trunks, SIP
endpoints and other SIP related issues. Even though these traces are in
clear text, these texts can be gibberish unless you understand fully
what they mean. This document attempts to br...
