[OpenSIPS-Users] Polycom REGISTER loop

[Duane Larson]

So you say you "closed gaping holes".  Are you saying that the local
polycom phone are behind a firewall?  If they are behind the firewall then
you need to figure out why the 200 OK is not making it to the polycom
phones.  It could be because Polycom doesn't support rport (just a shot in
the dark from the info you have provided).
