[asterisk-users] Getting confused on signalling mode Vs framing and encoding: T1 CAS

[Thinselin, Vincent]

Hello,

I'm trying to make my asterisk box to act as a telco, in order to reproduce a US environment in europe.
Our telco provider is giving us those settings:

ESF
B8ZF
Inbound = E&M Immediate
Outbound sig =Wink Start
Yield to Glare = Yes

Those trunks are using CAS for signaling.

I have tried many configs/combinations in zaptel.conf and zapata-channels.conf

In zaptel.conf, when having something like
span=5,0,0,cas,b8zs
and in zapata-channels something like 
signalling=featb

I end-up in the log file with something like
chan_zap.c: Got hook complete in MF FGD, waiting for wink now on channel 125

If in zaptel.conf I put something like 
span=5,0,0,esf,b8zs

My call is immediatly stopped:

Jan 24 17:17:33 DEBUG[25076] chan_zap.c: Got event On hook(1) on channel 125 (index 0)
Jan 24 17:17:33 DEBUG[25076] channel.c: Didn't get a frame from channel: Zap/125-1
Jan 24 17:17:33 DEBUG[25076] channel.c: Bridge stops bridging channels SIP/2707-0083be10 and Zap/125-1

What is the correct zaptel.conf for my case ?

If I specify esf in zaptel.conf, where do I mention I do CAS for RBS ?

Thanks.

V.Thinselin
