I always use a jitter buffer with IAX2.  (that's all I use, no SIP)

--------8<-------- iax.conf --------8<--------
pingtime=1
lagrqtime=1

jitterbuffer=yes
;dropcount=3
maxjitterbuffer=350
maxexcessbuffer=100
-------->8-------- iax.conf -------->8--------

I don't think the pingtime/lagrqtime parameters are needed anymore, I was just 
goofing around with them when I was playing with this.

I have found with the SDSL modems we're using that you need to back off to 
about 75% of the modem's capacity in order to prevent the modem from 
bufferring.  I should have just used HDSL endpoints (4 wire, powered) -- 
those buggers don't buffer anything.  :-)
