I don't believe MGCP supports the b-channel bonding necessary for video calls. Not sure if H.323 does but I think you may need an MCU for this.<BR>

We have MGCP gateways connected to the PSTN over PRI. We used to have a Polycom ISDN<->H.323 gateway, but got rid of it due to low utilization (i.e. only 1 ISDN video call per year)<BR>
<BR>
I’m wondering if it’s possible to reproduce the functionality via our Cisco voice gateways? We run 2821’s with 12.4(19) IOS. The video endpoints are various flavors of Tandberg codecs.. they can call the PSTN via Call Manager and get voice only with no issues.<BR>
