[Asterisk-Users] IAX: Auto-congesting call due to slow response

[Mimmus]

Hi, 
I have a IAX2 trunk between two sites (connected with an high bandwidth
link) but sometime/often I get:
 chan_iax2.c: Auto-congesting call due to slow response
and call is dropped (and routed on a PSTN link).
In iax.conf, I have:
 [iax-out]
 username=iax-in
 type=peer
 trunk=yes
 secret=xxxxxxxxxxx
 qualify=yes
 host=xxx.yyy.zzz.32
 auth=md5

Any idea? Perpaphs is due to 'qualify=yes'...

Thanks
