asterisk users - Oct 2004 - chan_iax2.c:5390 socket_read: Rejected connect attempt from

I've been messing around with my config files and now iax->iax calls do 
not work anymore.

I think I did not change anything that would break this but yet it does.

If I do 'iax2 show peers' the remote server show up OK on the console
yet
I still get an error.

The server that is placing the call gives an :
chan_iax2.c:5495 socket_read: Call rejected by x.x.x.x: No 
authority found

The server that should receive/accept the call shows:
chan_iax2.c:5390 socket_read: Rejected connect attempt from x.x.x.x

Any idea's?
