SIP Trunk From and To header questions
Hi support,
We are going to setup a SIP trunk with customer; and our SBC also connect to our softswitch.
Now we are facing the problem that, the INVITE we send to customer; sample as follow:
From: 85291687093 <sip:85291687093@192.168.64.9:5060;transport=udp;user=phone>;tag=vtaxpzyq-CC-1002
To: 831397444404131 <sip:831397444404131@192.168.77.21:5060;transport=udp;user=phone>
How could we do change back the IP address in FROM & TO to be public address?
Thanks for support.
