Video calls over E1 ISDN PRI link

[abrimawi9]

Hi All

I have an ISDN E1 PRI Link through MGCP gateway, the telco say that they will provide a Video call service through this link for up to 30 calls!! is that possible (voice is working fine)??

What I know is a 64 k provided by each ISDN channel is not enough for Video calls unless using MCU or a gateway to aggregate the isdn channels.

Other people suggest that with H323 gw this can be done.

Call flow: Mobile Phone ==> ISDN ==> MGCP (or H323 if required) ==> CUCM==>Video enabled phone

Please advise..Many Thanks

Hi,

H.323 is supported in Cisco ISR routers. It is recommended to have dedicated video gateways the Cisco (ex Tandberg/Codian) 3200 Series would be better.
