I have a Polycom IP 335 and a Linksys SPA921 here at my office (on the same desk, connected to the same hosted PBX; don't ask). The Linksys is not having issues registering. The Polycom, however, gets a 401 Unauthorized every time it tries to register. Both phones are behind the same NAT, both are registering to the same PBX, and they are registering to the same extension.

Any hints? I've reset both phones, updated to latest in v1.2.stable, etc. Still no joy.

For Polycom phones, in the Internal Profile:

<param name="NDLB-force-rport" value="true"/>
