E&M is the traditional protocol to connect two COs or PBXs
together.
E&M trunks are inherently symmetrical. So there is no subscriber or
CO side.
You
have to see about the higher level signalling protocol to make sure dialed
digits etc work right.

Subject: [Asterisk-Users] CAS SF Inband tone signalling problem
Hi,
I am having some problem in defining CAS SF Inband signalling on a Digium E100P card. The problem is that the syntax given in the sample zaptel.conf doesn't work. Can someone provide me with an example of the syntax.
I am trying to connnect asterisk with another exchange using a E1 CAS. I guess SF is the only option as the rest fxo,fxs,e&m etc are all subscriber end signalling. i need a CO to CO (or PBX to PBX) signalling...Somebody guide me on that too.
Any help will be highly appreciated.
Thnaks
Sincerly,
Janjua
