No. In order to do that, the channel driver that you use to terminate your SS7 signalling link would have to be able to understand MGCP as well. Neither libss7/chan_zap nor (AFAIK) chan_ss7 is able to talk MGCP to media gateways directly. > > Would you have any speculation about just how hard it would be to make > it > work?
