Describe the bug
We have implemented a call center that receives calls in a specific URI "phonebanking@hostname"and then handles them with the cc_handle_call method. This works well in Opensips 3.1.10. However, upon migrating to 3.4, the call leg (towards the agent) created by b2b_logic fails to generate a proper INVITE: while the agent URI is correct in the SIP METHOD header, the <To> header is set to the intial destination URI: "phonebanking@hostname".

The two invite messages: the first with opensips-proxy v3.1.10 and the second with v3.4.1

To Reproduce

Start opensips 3.1.10 and 3.4.1 with the provided configurations. Make sure to replace the DB URI with your mysql DB, and to create the "phonebanking-dev" flow, with agents a1,a2,a3.

Expected behavior

Incoming calls should be bridged with available agents. Instead they are rejected.

@kosniaz, could you provide me (off ticket) a pcap showing the 3.4 call (incoming call into CC and the call to the agent) ?

@kosniaz , as per my email reply, could you re-run the scenario for 3.4 but with log_level 4 and send me the logs for the calling (and the pcap).
Thanks
