You haven't said which protocol you're using to make/receive the calls. If
you're using IAX you need to allow port 4569 (UDP) through, if you're using
SIP, allow 5060 (UDP) and 10,000-20,000 (UDP) for the RTP streams. You can
adjust this port range if required in rtp.conf. You need 4 RTP ports per

It's pretty unusual for even heavy traffic to cause calls to drop
altogether. In my experience in heavy traffic scenarios call quality drops
massively, echo is introduced and a delay of about 2 seconds kicks in, but I
don't think calls have ever dropped altogether.

Is it possible the OP is on a *very* dynamic IP and the IP's changing in the
middle of a call?
