The reason that you need the nojitterbuffer in the iaxmodem config file 
is because you're actually getting at least some jitter.

IAXmodem's jitterbuffer simply fills-in gaps due to jitter with 
previously-heard audio samples.  There is no way to recreate the missing 
audio.  Filling-in the gaps with previous audio samples is effective in 
preventing premature carrier loss conditions, but it messes up the 
modems until real carrier loss does occur.  It turns out that in most 
cases it's better to simply skip over the missing audio.  The DSP seems 
to handle that quite gracefully.
Thanks,

Lee.
