Nortel MICS to Asterisk

Place an analog to VoIP gateway or another Asterisk box at the MICS site, point these to the current Asterisk box and configure its call routing to use these "VoIP" trunks.

There will be some limitations, most notable is that a call coming into the MICS and routed through the analog extension ports to the IP gateway wouldn't be able to send DTMF into the Asterisk (can't dial an extension on the Asterisks). A better solution would be to use a T1 trunk on the MICS to VoIP gateway (or analog E&M). I've used both of these to tie multiple MICS to VoIP trunks using Cisco Gateways. Other gateways will work, I just like the Cisco. And don't waste your time with the MICS VoIP gateway from Nortel, its just a 3rd party gateway rebranded for Nortel and frankly sucks.

Sorry if this shows up twice, I sent it yesterday but I didn't see it.
