You did not understant. I want the opposit: defining the same codec(s) 
for both incomming and outgoing for a peer using "type=friend". But at 
he moment it doesn't work. If a peer is defined with "type=friend", the 
"allow=" line(s) in the [peer] section only has effect for outgoing 
calls (originating from this peer). For incomming call (routed to this 
peer in the dialplan), the codec(s) defined with the "allow=" line(s) of 
the [general] section of iax.conf apply.



I would like that, with this, all the calls comming from or going to 
phone1 only use gsm or ilbc (even if phone1 support other codecs). A the 
moment, this only impacts calls coming from phone1. Call going to phone 
1 are only impacted by the codec choice in the [general] section and of 
course the codec(s) supported by the phone.
