Instead of this make notes of some of the faults in SIP that cause you
problems and start working towards SIP/2.1 or SIP/3.0. Just because you
weren't one of the people involved in designing the existing protocol
doesn't mean you can't work to change it.
SIP 2.0 has some unbeleivably braindead

NAT and SIP _can_ work okay under very very restricted circumstance.
Multiple SIP UAs behind one NATed IP _can_ work okay with a very

Hi John,

How about Asterisk and NAT? Can you please comment if the examples below
also work.
1x SIP phone <-> NAT box <-> Internet <-> NAT box <-> Asterisk
10x SIP phone <-> NAT box <-> Internet <-> NAT box <-> Asterisk
This all depends on the NAT boxes that you use. Th

That's a different part of the equation.
If Asterisk could interpret the Via: headers like the Cisco phones
do, that would solve the "Asterisk-behind-a-NAT" problem to a large
degree. Perhaps it already does; I've never tried putting Asterisk
behind a NAT, only SIP clients.

Please don't take the discussion of SIP interactions off list. I already
have NATed SIP clients working with *, but * still has problems where

You may be correct about the Via: header, but you're incorrect in the

Yes, I have one location where there are a dozen or so behind the
same NAT. Things work fine for inbound and outbound. I'm sure there
is a theoretical limit based on what an 8 or 16 bit integer can hold,
but I'm not worried about hitting that problem any time soon.

I'm uncertain why you're not able to get SIP working for your user

quite well and almost every 79xx or ATA-186 I have is behind a NAT,
and this configuration is duplicated across a dozen or more systems

Hi all.
I have come to the conclusion that there just isn't anything out there
for allowing SIP and NAT to work together nicely. This is rather amazing
considering that as far back as March 2000 there are documents
describing how to do it.
So I've started a really simple SIP and RTP proxy project
