I did set tos=lowdelay, but that will only help if the routers between me and Nufone honor the request.
I don't really know enough about QOS to monitor it if it's not on my own network though. I'll look more into that.

Do you know what QOS is ?
Do you know how lack of QOS can affect VOIP applications ?
If you don't then I sugest you learn that or pay for someone to teach you first.
You could be having ocasional packet drops.
Please reply to the list,

I've been having random problems when I make long distance calls using
either VoicePulse or Nufone. Sometimes the calls go through clear, and
other calls (or even just part of a call) the person on the other end
just hears garbled voice, or really broken up voice. Sometimes it lasts
for only a few seconds, but other times it goes on for a few minutes
until I give up on the call.
At first I thought it was just a problem with our ISP, but I also have a
Packet 8 phone that works just fine even when Asterisk is having these
problems.
I get decent ping times to the Nufone or Voicepulse servers (85-200ms)
and only minimal (0-2%) packet loss.
I've tried connecting with Ulaw, and G726(with Nufone), but it doesn't
seem to make a difference which codec I connect with, I still get the
same garbled sound.
I'm have jitterbuffer=no in iax.conf, but I've also tried it with
jitterbuffer on as well.
Local calls through the zap card seem just fine.
What could be causing these problems?
