[asterisk-users] TDM400P incoming route for DID

[Eric "ManxPower" Wieling]

As far as I know any signaling protocol you can get on a Channelized 
Voice T-1 you can also get on analog lines.  In fact these signaling 
protocols originated on analog lines and are simply emulated on voice 
T-1s.  Notice I said Channelized Voice T-1, not ISDN PRI.

Granted, analog lines with signaling other than Loop Start don't seem to 
be popular as they once were.  One of my clients has 4 analog E&M Wink 
lines going into their PBX (in addition to other loop start lines)
