From what I understand, the Media Gateway (in Megaco world language), is the 'client' if you will, while the call server/softswitch/call agent, is the 'inteligence'. If you have a gateway (either a small one or a trunk one), you would need yes, a Call Agent. I found this interesting link that has a summary on this.. http://www.javvin.com/protocolVOIP.html Who provides the Dial Tone would be, I assume, the gateway, the "client", either a "line side" one, like the Calix, MG9000 or others, or a trunk side gateway, like the MG15K in Nortel NGN deployments. In a Nortel CS2000/CS2Kc NGN, the 'megaco/h248 call agent' would be the call server itself (actually, the gateway controllers, that translate from PPVM to H.248, from what I can remember). You may also want to check if your gateway can't be changed to use another protocol, since H.248, AFAIK, is not exactly much supported in the OSS world > On Feb 16, 2008 5:05 PM, Julio Arruda <[EMAIL PROTECTED]> wrote: >> Chad Whitten wrote: >>> I have been searching for some documentation that would indicate if >>> Asterisk supports H.248 and everything I have come across seems to >>> indicate I should use MGCP which I would agree is a better choice but >>> unfortunately the equipment I am trying to integrate only does H.248. >>> >>> Could anyone point me to something related to this. >>> >> >> I've not seem anything on Asterisk being used as a Call Agent for H.248 >> gateways, but I've seem the question pop-up at least a couple of times >> in the past. >> I understand there are quite few gateways out there that support H.248 >> in one flavor or another.
