So my company has used Polycom in many of our conference rooms for the past 10 years. We had VSX systems, then HDX, and one room has gone to a RealPresence 700 system... before we started adding Cisco Telepresence units.
While our Polycom devices all use H.323 communication, making calls by IP address, the Cisco Telepresence systems are all setup with SIP, and I recently notice that network-based calling is DISABLED in most (if not all) of the Cisco Telepresence systems we have.
Because we hold meetings between older and newer system rooms, we occasionally are having a Telepresence system dial into a Polycom system or vice versa. But if we try and share camera and content at the same time, only the content is displayed. I worked with our local provider to get a TIP code for the RealPresence Polycom system (our newest device), input it under the options screen, and called the Cisco Telepresence system using a SIP phone number. But the same problem existed as before, content and camera can't be shared between Polycom and Cisco systems.
Any ideas what could be wrong? And is there any point in enabling IP-based calling, and trying to call a Polycom system using IP address, rather than SIP? I suppose there is STILL just so much I don't know about the Cisco Telepresence, I may not have enough information to ask the right question. But any help is appreciated.
