Ok, are you behind NAT? What are you doing there that iax is not connecting<br>
outbound with a source port of 44569?<br>
<br>
I just pulled a dump of your traffic to the registration server and I see<br>
you're hitting it with a source port of 54799, not 44569. I think this has to<br>
be some nat funkyness, using a different outgoing port vs incoming.<br>
<br>
Can you check that and give some details if you are behind nat as to the setup<br>
you have?<br>
<br>
Thanks,<br>
