Point-to-point Video Calls over PSTN/ISDN

[joguevil2008]

Hi,

We have two independent locations,one of them has CUCM 6.1 and the other side, CME 7.1. Both can make video calls locally (with 7985s and CIPC).

Is it possible to stablish point-to-point video calls between those two sides natively over PSTN/ISDN? Is it necessary another device - mcu - or something like that?

I will appreciate your help because I am new in video management over CCM/CME environments

Thank you in advanced

Why PSTN, where the bandwidth necessary is complicated and expensive to achieve.

You should have video, as well as voice calls, go over IP/VPN.

The best help I can offer here is the document explaining the configuration on IOS:

I have yet to encounter a customer who has an H.320 requirement. Most do this over IP these days as Paolo recommended.

Thank you both for your help, as I mentioned I am new in this area and need your advice. I will suggest IP network as you recommend, although I will also work on the document you offered because this is part of a solution that requires the use of ISDN and Polycom devices so, you will see some other posts from me , please forgive my ignorance and, again, thank you very much for your help.
