Hi Steve,
Actually, I have a strange issue. If I have a single UDP IP:Port listening, most Providers/Phones have two-way Audio/Video, however, with some Providers/Phones, I need to have two UDP IP:Port listners in order to get two-way Audio/Video. Here is the strange thing. If I enable two, the Providers/Phones that worked when I had a single listener only have one-way Audi/Video.
Can you give a little more details on why you need 2 IPs for some providers/phones?
I use Kamailio 5.1 and Asterisk 15.3 (pjsip). This behavior is so strange,
Are you proxying RTP through Kamailio (rtpengine/rtpproxy) or is it going directly from the carrier<->asterisk?
