[Asterisk-Users] IAX2 Rejected connection attempt (voiptalk.org)

[Mark Benson]

Hi all,

Have a problem that I have been battling with for a few days now with 
help from voiptalk.org support.but I thought someone here might have 
seen this before.

I have an asterisk box running on a real non nat'ed ip address with an 
incoming number from voiptalk.org on IAX2.

The problem I am seeing with or without firewall rules in place (port 
4569 udp open or all ports open ie firewall rules flushed) is rejected 
connection attempt from xxx.xxx.xxx.xxx which is voiptalks IAX server...

The real killer here is that this was all working but my inter asterisk 
sip connections were not transmitting voice, after changing 
canreinvite=no to canreinvite=yes in sip.conf the sip connections 
started sending/receiving voice ok but the incoming calls were being 
rejected. I can also dial out on voiptalks IAX connection happily. And 
just to be sure I changed the canreinvite back the problem remains.

I have all but rebooted the box. I have restarted asterisk and checked 
everything again, but I just can't see why this is happening.

Cheers,

Mark
