Hi There
I’ve setup a freepbx system (with asterisk 11 and freepbx 2.11 ). All is working very well expect external extensions. I’ve forwarded all required port on our router (UDP: 5059, 5061 and 10000-20000; TCP 5059).
If I call my external phone it rings and I can hang-up or take it, put it on hold, but there is no sound in both directions.
And now the strange is, if I enable “general NAT” on our Router (all trafic is routed to the pbx) it works fine.
I enabled RTP debug via CLI and the output with NAT enabled:
Sent RTP packet to 178.197.225.102:9155 (type 00, seq 043640, ts 2863235832, len 000160)
Sent RTP packet to 192.168.1.104:63912 (type 00, seq 023606, ts 3591295144, len 000160)
Got RTP packet from 178.197.225.102:9074 (type 00, seq 021514, ts 1829640586, len 000160)
Without NAT enabled:
Sent RTP packet to 10.198.191.195:60588 (type 00, seq 053218, ts 2877308328, len 000160)
Got RTP packet from 192.168.1.104:50246 (type 00, seq 004265, ts 2877308495, len 000160)
So, whats wrong here, is the fault off our Router or is it an other thing? Maybe its using a port that I didn’t forwarded?
Technical background:
192.168.1.104: is my softphone on my PC
178.197.225.102 / 10.198.191.195: is my mobile phone, connected via mobile network (I think with NAT44 )
PBX: yes the singnalingport is 5059
And here are the settings from freepbx:
