Well Asterisk does have the MGCP protocol built in, but I am not sure what it's capabilities are. The MGCP capable phones sometimes work, but I know of no one using a channel bank with it. Still can't find a manual or info on the adit 600. Not worried about power failure, this thing came with a 48 Volt battery backup. Since it was free, what do I have to lose? Don't have the CMG card though, just the TDM controller and 3 8 port FXS cards. All I want is a better alternative to get a lot of FXS ports for extensions instead of using multible ATA boxes. What's the IP address the ADIT has on it?
