Does anyone have a good explanation of the differences between MGCP and H.323? I have been searching online but I haven't found any real good information.
The reason why I ask is because I currently have MGCP configured on my voice router with CallManager talking to it. I would like to monitor the active voice ports on the router but I guess (per TAC) when using MGCP, the router is like a dumb terminal and doesn't do any of the call processing so it doesn't track the number of active calls. These stats are obtainable from CallManager using the Real Time Monitoring Tool but I would like to be able to poll a specific OID using SNMP and be able to graph the results historically.
TAC mentioned that I could change the protocol from MGCP to H.323 and I would have some different options as far as OID's to poll. I guess with H.323, the router actually does the call setup and teardown and can track the stats of active calls, which would give me what I am looking for. I just don't know how smart it is to change my configuration and what kind of risk I am going to incur. I read that H.323 is more difficult to configure and requires more administrative overhead, where MGCP is very straightforward. Does anyone have any insight to this?
I just want to monitor active calls using SNMP, it cant be that hardâ¦
