[cisco-voip] CUCM Video over PRI

[Ryan Ratliff]

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.

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)



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.
