I am using polycom HDX 7000 series VC. We used to call HQ using the IP of their VC but now HQ wants the call setup to be done using phone number. I checked the docs for it and it says, it can be done. Can anyone help me with the configuration part of it? Do i need to work around the gatekeeper settings? Is it even possible?
For a HDX7K I'm pretty sure you need an ISDN module to make this work, but once you've connected it, and enabled ISDN (as per the instructions in the Admin Guide) you will be given the option of the call-type on the dial window (H.323, SIP or ISDN).
It seems nuts that anyone would want to go back to ISDN - are you sure they don't just want you to dial via E.164 over IP via your gatekeeper?
