Hello Experts,
Below is the Call Flow, We are trying to modify the 'Contact' header on 302 Moved Temporarily message. The Call is routing to the CUCM without an issues. But we are facing challenges to copy the Values to the INVITE sending to CUCM. We need to copy the values to either SIP-Req-URI or To header (Please Refer Sample SIP Messages for more details.
===================================================================
Call flow:
ITSP >> CUBE >> 3rd party server (oracle SBC) >> Received 302 Moved Temporarily(sending back to CUBE from Oracle SBC after Authenticating the Call) >> CUBE will generate a new Invite and send the call to CUCM
Invite generated by CUBE after receiving the 302. It changes the contact header filed.
we need to keep the contact header just like it was received in 302 Moved Temporarily.
