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?
