Remote Extension no audio! (Even after HOW-TO)

when I do tcpdump -n dst portrange 10000-20000 I see nothing =(

EDIT:
with some delay I see
193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.019951 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.038925 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.059725 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.080288 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.100739 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.116033 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.135000 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.154277 IP 193.227.104.40.34774 > 192.168.1.50.15260: UDP, length 45 16:54:13.176651 IP

That shows that you are sending udp trafic on port 1560 to 192.168.1.150 but whatever it is replying (if anything) is not making it your machine.

No actually that traffic is caused by the other extension…I can’t see the extension’s IP in that log!

15260 and that assumes your box is 193.227.104.40, if that is your vsp then the local machine 192.168.1.50 is not replying.

is the IP of my voip trunk and my box internal IP is 192.168.1.50

BTW Thank you for your time!!!

tcpdump allows you filter by several hosts (host 192.158.1.150 and 192.168.1.2) for example an then your portrange

In the SIP settings of freePbx instead of dynamic IP i put static IP and it works!!!
ridiculouse though…

Not ridiculous. If you had done an asterisk ‘sip show settings’ I bet your system was not resolving your dynamic IP.
