I have a customer that is deploying CVP and as such needs H323 gateways. All of there current gateways are MGCP and they do not want to change that, and they don't want to have buy second gateways to support call center calls. In the SRND guide for CVP it states mgcp and h323 can be on one box, as long as h323 controls the trunks for cvp calls. I have never tried running mgcp and h323 at the same time. What pitfalls or limitations are there (srst?)
I am doing this in a similar environment (cvp 3.1 with mgcp/h323 on the same box).
The caveat of "as long as h323 controls the trunks for cvp calls" is pretty big though because the customer would have to have seperate pri's/t1 cas links just for inbound cvp calls.
We have tested SRST and it works properly. MGCP falls back to h.323 and the inbound calls over that PRI (the pri controlled by MGCP) route properly. Inbound calls to the "CVP PRI" still routes calls properly (assuming you have alias's, num-exp, etc setup to handle these calls appropriately.)
Well keeping the cvp calls on separate pri?s is not an issue since they will be new circuits. My big concern was SRST, and how that would be impacted. This customer wants a very conservative approach, so I just want to ensure that I don?t step on my own toes.
I have seen people running both protocols on the same router as long as they dont control the same trunk. If a dial-peer has service mgcpapp command , all traffic coming in from the corresponding trunk that MGCP controls is backhauled to Callmanager. So H323 dial-peers wont even see the call signalling. So the trunk (if a PRI) should not have the "Service mgcp" keyword ino rder for H323 to control the trunk.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
