asterisk users - Nov 2011 - Polycom Phantom Ringing

I have a Polycom Soundpoint IP335.

 

There are no inbound routes set to the phones yet.

 

However, the phones are getting phantom rings.

 

What is the legitimacy of these calls? 

 

Is there something I need to block to stop it?

 

I believe its people trying to hack the phones/phone system but I cannot find
where I read that before.

 

Thanks,

--E

If your phones are being "hacked" you have a firewall problem.  Your
phones
should only be registering to your local DHCP server and your Asterisk box.

DHCP Server 192.X.X.X

Asterisk Server 192.X.Y.Y

Phone 192.X.Z.Z
