reINVITE to refresh the session answered by SBC?
Hello!
I have a question about session expiress process and I would like to learn more about this.
I know how to modify who is the refresher using Session-Timer-Profile and that works fine but I have a question about the signaling process.
Imagine there is a call established between PBX-A <---> SBC <---> PBX-B. The phone from PBX-A places a call and phone from PBX-B answers the call.
The sessión between PBX-A and SBC has a session expiress of 90 and the refresher is UAC (PBX-A)
The sessión between SBC and PBX-B has a session expiress of 180 and the refresher is UAS (PBX-B)
