Disabling Call Progress Analysis


is there a way in Asterisk to disable CPA (call Progress Analysis). I’m not sure if this is the correct term but here is what I want to do:

I want to use Asterisk as a T1 groomer, I got two Quad ports boards. I will have 6 T1 from my PBX (T1 cross over cable) going out on two T1 that is connected to Asterisk. 6 T1s from my PBX goes to Asterisk and 2 T1s from my carrier which is a PRI.

here is my current extensions.conf: basically any calls comes in from dahdi g1 is sent out via g2. I dont want Asterisk to play its own dial tone or even detect disconnected number tri-tone etc… how can I just bridge the two channels?

exten => _1.,1,Dial(DAHDI/g2/${EXTEN},r)

hope the question is clear…



In chan_dahdi.conf



restart the dahdi module.

Asterisk is a back to back user agent. It is always going to terminate signalling and regenerate it on the other side.
