SIP and Virtual Shelf

SIP and Virtual Shelf

SIP and Virtual Shelf


So our company recently purchased a PolyCom video conferencing system. Apparently, the conference phone requires a "SIP connection" in order to be used on our network and TDE600 PBX. I installed the single SIP license, but I'm not sure if I require a virtual SIP Trunk card, or a virtual SIP extension card, or both. Also, our PBX has no room for a virtual extension card as all 4 slots are filled with two IPCS4 and twp V-IPEXT32 extension cards.

RE: SIP and Virtual Shelf

No room, no problem.

You do not need to run the Polycom through your PBX.
The PBX may not even support video as well.

So, get SIP Service with a separate telephone number and run the Polycom outside (not connected) to your PBX.

I suggest Callcentric.com for a SIP Service Provider.

They are in Manhattan and are close to you and easy to set up.

RE: SIP and Virtual Shelf

You will need to install SIP exension card, are you using 32> IP phones?

RE: SIP and Virtual Shelf

Right now, just one.

RE: SIP and Virtual Shelf

WhiteGooner ... I misread you question. I have 58 IP phones, so I can't get rid of any of my V-IPEXT32 cards. I also have 8 cell stations and need the 2 V-IPCS4 cards. So I guess I can't add another virtual slot/shelf on these systems?
