[Asterisk-Users] number of simultaneous calls with E&M

[Michael Welter]

I've done this with a Fujitsu 9600.  With T-1 interface cards on both 
the legacy PBX and Asterisk you'll get 24 voice channels.  If the legacy 
PBX is capable you can configure the circuit as E-1 and get 32 channels.

Mine works well.  With E&M you won't get the caller's name but you will 
get caller's number (CID).
