The question mark denotes the fact that I lose trace of RTP packets
here. Any idea why the packets are not relayed ?
What ports do you have opened and forwarded on your firewall/router?
I forwarded the ports 29980 to 30000. The third party SIP server
knows that, and my client is configured to use only ports in this
range as well.
Should I understand that the router should send the packet back to
Kamailio which then send them to the SIP server ? If it's the case I
should investigate on the router side.
On a side note, as for Wireshark, RTPproxy does not see the RTP
packets: INFO:remove_session: RTP
stats: 0 in from callee, 0 in from caller, 0 relayed, 0 dropped
