If all signs point to mis-configuration of your firewall, why not prove them wrong (while in the process getting more details).... just add wireshark to the mix. You can then watch the traffic and be able to quickly identify if any is being lost due to blocked ingress/egress ports.<br>

Hi out there,<br>
<br>
I think i've everything set up properly, outbound calls are working fine, but<br>
at incoming calls I can't hear anything, but the other one is able to hear me<br>
perfectly.<br>
<br>
I'm using an asterisk 1.6.1.10 in my internal network in a NAT, connected to<br>
my sip-provider using a trunk.<br>
Firewall settings on the router are:<br>
forward UDP port 5060,5004,10000-20000 to asterisk server<br>
Firewall on asterisk server is switched off (for better testing)<br>

Auntie google is not very helpful for me.<br>
They all say, it looks like a firewall problem on the router.<br>
But I'm sure this is set up correctly.<br>
<br>
Any ideas?<br>
