what is the good way to understand the Sip events between all three applications
3 way Sip communication is little confusing to me.
any help would be appreciated
Thanks
Good way…tricky…not easy definitively…just sit down, study each scenario and follow the SIP messages exchange.
Basically SIP Server sends requests to RM and RM to MCP.
Thank you for the response and a question
does the call id generated in sip t-server for a call will remain same in RM and MCP or it will be different for each app?
Call ID is an ID for that call, will be valid until the call exists SIP Server.

ConnId is generated by TSrv/SIPSrv,
GUID/UUID is generated by RM.
There’s multiple unique key, but those two are the main one for me.
I would like to trace/troubleshoot a call
so In sip t-server i need to look for call-id and then in rm GUID and in MCP another call/guid?
is this how you usually trouble shoot or any other tool available?
I use connid, the ANI and time of call
CallID can help too but I am not quite a fan of it

If you’re looking into troubleshooting SIP to GVP , I find it best through the Call-ID, as that is what is used by SIP.
ConnID for everything else.
