asterisk users - Jun 2005 - Polycom & VPN trouble

Hi All,

I am a remote office that is connected to my office via openvpn on UDP. 
Voip has always worked well (after discovering g729). Initially I used a 
softphone, then an analog set on a sipura 2000, then a polycom IP500 (I 
still LOVE this phone). At that point, I started noticing that the 
polycom doesn't ring a lot of the time. Since I was desperate for a 
phone, I didn't upgrade the firmware, and just got the phone going via 
web interface.  I was hoping that a firmware update and proper 
configuration would help.

Well, I just got a new Polycom IP300 and upgraded the SIP firmware to 
1.4.1 and bootrom to 2.6.2 (I think, off the top of my head) and did a 
'proper' config via FTP. I brought this phone over and it does the same 
thing.

Funny thing is that if I use xten on my laptop (which also rings when 
this particular extension is rung), the softphone AND polycom always ring.

There is no NAT and no firewall rules on the VPN (I've elminated them as 
a troubleshooting step :-).

I am running a fairly recent CVS HEAD version of *, on Suse 9.2. The 
phone rings all the time on the same network as the * box. Before I 
started digging any further into this problem, I was wondering if anyone 
here has experienced these issues, and what you did to rectify them?

Thanks,
Tim

Have you considered playing with the timeouts?
