I've been doing video conferencing for years either over our network between sites or via ISDN to the world. We are now installing a system with a VCS Control, a VCS Expressway, a MCU 4501, and soon TMS to run the whole show.
During the initial configuration, I am to enter our SIP domain in both the Control and the Express. Where does this come from and how do I get one? I can't imagine that I just make it up out of thin air and hope for the best.
Yes, I know the rest of the world has been using this for years, but this is entirely new to us and I'm mostly in the dark as to how to make this work.
And I probably sound like some old codger that hates change, but I'm not really. I'm just lost.
