There is no problem, simply asterisk is attempting a native peer-to-peer 
IAX2 call and it can't, so it stays in the middle bringing both 
signalling and media.

This links could help you:

http://doxygen.asterisk.org/trunk/Config_iax.html

;transfer=no                 ; Disable IAX2 native transfer
;transfer=mediaonly          ; When doing IAX2 native transfers, transfer only
                              ; the media stream

I'm not sure that this is an exact solution to your problem, but it may 
help. When Asterisk transfers an IAX to IAX call, by default, it 
attempts to make it a peer to peer call. So when it transfers, the 
Asterisk box is removed from the loop. You can changed this behavior 
with this parameter.

notransfer = yes | no

If an IAX phone calls another IAX phone by using a Asterisk server,
Asterisk will transfer the call to go peer to peer. If you do not
want this, turn on notransfer with a "yes". This is also settable
for peers and users.

Best regards
