Asterisk's chan_mgcp does not support being a media gateway right now. 
You can only control media gateways.  Also, Asterisk doesn't currently 
support signalling reception on anything other than a DS0 directly 
connected to the machine.

You're not going to be able to control media gateways either that are 
signalled via SS7, since chan_dahdi does not speak MGCP.

These are both things that I would like to improve though...
