Polycom IP7000 conference calling

[jeff1203]

Does anyone know how to get more than three parties on a conference call using the Polycom IP 7000.
I have the phone installed as a sip user in system manager with a phone type 9620SIP. It registers just fine and works for making calls. However it is limited to just a 3 party conference call while my digital phones can do up to 6 parties on one conference call.

It is probably doing a conference locally on the phone itself instead of using CM.
