[Users] Registration Weirdness

[Douglas Garstang]

I have a series of Polycom phones that are tying to register with OpenSER. The phone sends a REGISTER message, and OpenSER replies with Unauthorised (all normal). The phone re-sends the REGISTER with the credentials, and OpenSER sends Ok.

Here's where it goes downhill. The polycom's appearance display does not change from an unregistered to a registered state, ie it does not change from an empty phone to a filled in one. It doesn't think it's registered eventhought it's gotten an OK. Then, a regular intervals it keeps trying to register again, because it still thinks it wasn't successful.

I have some other Polycom phones that are not doing this. All have the same SIP software version, and all essentially have the same xml config files, with minor variations. Happening with OpenSER 1.0.0 and 1.0.1

I have pasted ngrep output of one of these below. Anyone got any ideas?
