Hi, AS53XX/54XX supports MGCP but unfortunately not with CUCM so far. Only Cisco PGW/BTS and some third-party solutions can talk with them via MGCP but I don't know why Cisco is still restricting them to use with CUCM. I also found these AS series universal voice gateways doesn't support RSVP as well, what a crap! But you can see all these on it's supported features!

Hi,

Thanks for the info, I know that AS53XX/54XX supports MGCP. But my answer was according to your question "AS5350 and CUCM MGCP, can I?" That why I was suggesting you to use h323 in AS5350 so that u can use it with CUCM.

Thank you !! but its a weird limitation
