<pre>I am also using Polycom behind NAT without problems. But my asterisk box is not natted (so I have no externip setting in my asterisk).
My setup is Asterisk->internet->nat->polycom601/501/430/301
(PS: Hopefully posting in plain text after adding digium.com as a text-only domain in thunderbird :))
Regards,
Ove

<pre wrap="">Yes, the Asterisk boxes were on private addresses. The Polycoms are also
behind a NAT. Yes, I tried using externip in sip.conf and this allowed
registration, and calls to be placed, but no audio. Unfortunately,
Polycom does not support STUN.

<pre wrap="">Your problem is not Linux-HA, it looks like that is fully functional.
Your problem is the same one many people come across. You can't put
Polycom phones behind NAT, it won't work.
If you have to have the phones behind NAT, which I advise against, use
Linksys which probably work better, and use a SIP aware NAT device.
Better still, put the phones on the same network as the Asterisk PBX and
say goodbye to your problems.

<pre wrap="">Thanks Chris. Unfortunately, these solutions aren't an option. I guess I
was hoping someone had found the silver bullet or some undocumented
Asterisk feature that solved the issue. Back to the drawing board.
