We have a H323 Gateway that support 12 analog lines from the Teleco. We are going to a PRI to this gateway and remove the analog lines (actually port them over to the PRI). We are thinking that it would be better to convert the gateway from H323 to MGCP. Looking for comments, recommenations and insite from anyone who has done this.
I think Cisco's best practice, unless it has changed, is to make your gateway's MGCP if they are on net. Over a WAN then make them H323. However, my best practice is to make then all H323. I love the command line and it seems much more powerful and easy to use especially if you need to make a change to a route pattern etc on the fly or make any config change for that matter. When you do such a thing with MGCP it resets the entire PRI on you which causes you to make needed changes after hours. To me there are many benefits of H323 that outweigh MGCP, there many discussions on the forums about this exact topic. My two cents.
Always a topic of debate in the forums. My position is you pick the right protocol for the job. Which means you have to define the job in terms of technical and non-technical requirements. If it turns out multiple protocols can address the need equally, that's awesome because then you have a choice. However, I suspect that your non-technical requirements may give an advantage to one of the protocol choices.
My thoughts on the protocol choices are outlined here:
I'd figure I would save myself typing time!
