Hi, My IPVC 3511 just arrived, and I started hooking it up, but it constantly tells me that there is no gatekeeper registered. I am only planning to use SCCP clients, so I assumed I would not need a H323 Gatekeeper. Is there another kind of gatekeeper that I would need? I am running CM4.1 and IPVC 3511 ver4.1 Thanks, Avidan
