[Asterisk-Users] 2 IAX2 calls, bad audio

[Ing. Angel Gomez Garcia]

    Good evening all.

    I'm having this strange behavior when dialing two or more 
simultaneus calls via IAX to other * boxes. Sound starts to have more 
latency, wich increments until it's almost impossible to talk (6 or more 
seconds), I try this calling with two grandstreams, one grandstream one 
tdm410p, one tdm410p and sjphone, sjphone and one grandstream, the 
result are similar.

    I have only gsm and g729 enable in iax.conf ( no g729 license... yet 
), if I hangup one of the two calls, latency goes down to almost none.

    The strange thing is that one of my friends tryed calling me with 
one grndstream and one XLite and that combination does not seem to 
increase latency, but if he calls me with two granstream he has the same 
results.

    I also try calling 2 different * boxes, and the results are the 
same, continuos increasing latency.

    Has someone look at similar results ?

    Thank's.
