Ghost calls VVX450

[babalucha]

Hello Eyeryone , hope everyone is doing well. Please forgive me if this been asked and solved by someone already which I m not aware of. I m new to Polycom Phones,  we usally them use other brands but we have run into a client has about 15 Phones which includes mix n match of Vvx 310,311 & 450. 

Customer isn't happy with existing voip service provider and would like to use existing Polycom phones , so we tried to switch the very first one to our server and phone is keep getting GHOST Calls. We have generated a ticket with HP but so far we havn't heard anything back, it's been one day passed already and no answer  from Tech Support Team yet.

Hope someone can guide us how to only accept invite message from registered server. Thanks  a lot in advance:)
