Hi Anca, I was wondering about that because I saw the tm:t_uac:next_hop part pointing to the RURI, and then attempts to lookup the domain and SRV records.
I also noticed that my script was sending two 100 trying messages, which after removing my manual sl_send one, i was still getting a 100 trying message even though my t_relay has 0x01 flag set. Can I assume the following then: An INVITE from a UAC to the OpenSIPS SBC should only ever call the b2b_init on replies from the OpenSIPS Router server, as that is the topology we want to hide. Calls originating from the OpenSIPS Router server must also call the b2b_init for topology hiding. Or have I missed the boat here?
