[Asterisk-Users] Connect attempt rejected error message

[Brian Wright]

Hello,

This is an odd one.  My brother has installed iaxcomm on his notebook.  
He connects to the internet through a WiFi gateway (using DHCP).  So, 
it's probably a one-way connection (and I think this may be part of the 
problem).  Anyway, iaxcomm registers with the Asterisk server correctly 
and I see the period refresh of the positive authentication.  He can 
receive calls fine.  But, when he goes to place a call or do anything 
with a command, I see the following:

Dec 22 23:14:21 NOTICE[22005]: chan_iax2.c:5405 socket_read: Rejected 
connect attempt from XX.XX.XX.XX
 
I'm confused by this.  I thought that if you were authenticated, you 
could send commands to the server.  Is this not the case?  Does the 
server try to connect back to the client for verification and, failing 
that, reject?  I've tried reading through the check_access() in 
chan_iax2.c to determine the access rejection cause, but (after reading 
the code) I realized quickly that I'd have to put Asterisk in debug mode 
to figure it out.

I did notice that the other clients that were able to connect and send 
dial commands after authenticatation which are using port 4569 (after 
the IP).  My brother's computer authenticates using port 64015 (or some 
high port) after the IP.  I don't know if this is related, but it seems 
odd to me that if you can authenticate in to receive calls, then you 
should also be able to place them.   Is there some kind of configuration 
setting that gets around this?

Any help or experience is appreciated.
