[asterisk-users] Polycom Phantom Ringing

I have Polycom 501's and they keep a log of all calls.  I would expect the
335's to have that capability as well.

Well this is a remote site.

I am running 1.4.26

I have multiple polycoms that do not experience this.

They are getting dhcp from their local router.

I am wondering if it could either be a bug in the polycom firmware or
something like a probe into the phone.

I am pretty sure I read that phantom rings are sip calls to a phone where
they are probing for extensions or something; cant remember.

I don't think that's it. I have had the Polycom on my test site ring
unexpectadly. It could be a bug in asterisk. Are you using 1.8?
