[asterisk-users] Problem with Polycom Soundpoint IP 320 Hardphone

[Glenn Gillen]

Hey all,

I've setup my asterisk install on a CentOS5 server, I've got a few
IAX2 and SIP softphone clients connected on the same subnet and at
least 1 external IAX2 softphone. However I'm having some difficulty
getting the Polycom hardphone to function correctly. Watching the logs
and debug trace it:

- Registers correctly
- Is able to make calls to other peers

However it is not able to answer calls made to it. That is, the
handset actually rings, but I've no way to answer it. The answer soft
key, picking up the phone, etc. all have no effect. And I'm at a loss
as to what setting should be altered to fix it. Any ideas?

Possibly a tangent, but also affecting this handset, is that trying to
dial out over an external SIP trunk fails on the first attempt. But
calling an internal peer and then trying a second time makes it
mysteriously work.

Any help greatly appreciated,
