[Asterisk-Users] MeetMe: lots of buffer overruns/underruns when connecting over IAX

Hello,

Situation: I've got two asterisk 1.2.4 servers, connected to each 
other over the internet with IAX2 with about 20msec delay.

One of the servers is hosting MeetMe. It's working fine as long as 
only SIP phones connected to the meetme server participate in the 
conference. As soon as a participant using IAX2 is connecting, lots 
and lots of buffer overruns and underruns are generated:

Apr 20 17:37:27 NOTICE[20970]: app_meetme.c:1276 conf_run: Audio 
bytes: 640  Buffer size: 320
Apr 20 17:37:27 NOTICE[20970]: app_meetme.c:1276 conf_run: Audio 
bytes: 320  Buffer size: 640

bytes: 320  Buffer size: 640
Apr 20 17:37:28 NOTICE[20970]: app_meetme.c:1276 conf_run: Audio 
bytes: 640  Buffer size: 320

This always happens, even if there's only one participant in the 
conference.

All phones are Supura/Linksys SPA-941 phones. Everything is working 
fine (users can talk to each other, voicemail is working, etc), exept 
for meetme.

In meetme.conf I've got audiobuffers=32, which doesn't help.

Any clue?
