Hello:

I am evaluationg to buy a line conentrator for POTS that registers each line using the H.248 or MEGACO protocol. I want to connect this using asterisk but I am not sure of the compatibility of this protocol. Can somebody confirm if asterisk will register H.248 clients.

Thanks

H.248 is otherwise (and more commonly) known as MGCP.
Asterisk does support it see http://www.voip-info.org/wiki-Asterisk+MGCP+channels

Note that Asterisk can only operate as a MGCP server with clients registering with it. It cannot act as a MGCP client and register itself with another server. I would expect you would need Asterisk 1.4 aswell.

Is there any reason you want to use MGCP? There are quite a lot of SIP devices available.

H248 is not MGCP, it is Megaco. Both are gateway control protocols, MGCP is an IETF spefication and H.248 is from ITU. I don't thin Asterisk supports H.248 currently.
