[Asterisk-Users] Horrible MeetMe performance

[Dan Morin]

Make sure that if you're using anything other than zaptel hardware, it
is running uLaw as the codec.  Anything else will produce ever
increasing delays.

My setup has all of our VoIP lines coming into my main box, and then I
have a separate box running asterisk only for meetme with an iax2 trunk
between the two running uLaw.  It seems to work fairly well.

Did you ever have any luck with improving the MeetMe performance? We're
running into the same problems....

Hey folks,

Using FreeBSD 5.2.1 and I've got the current zaptel driver installed 
from ports (0.8_1) and current ports asterisk (1.0.1).  I've set 
options HZ=1000 in my kernel config, recompiled and rebooted and as far 
as I can tell, I've done everything right but when I try to use the 
conference, the audio is very delayed, choppy and segmented -- totally 
unusable.

At the suggestion of someone on #asterisk, I cvsup'd * against digium 
and used that instead of ports, but that didn't seem to help either.

FYI:  When I said above "when I try to use the conference" I meant 
using two non-voip phones, specifically a cell phone and a land line.  
I'd dial the number for my asterix box which is in itself a b channel 
on a PRI answered by a T100P on a friend's * box and sent via IAX over 
to my * box.  Not sure if that matters, but I figure I'd mention it 
anyway.

Anyone have any ideas here?
