[Asterisk-Users] CAS SF Inband tone signalling problem

[Alfred R. Nurnberger]

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.

Regards.

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
