[Asterisk-Users] Re: how to distinguish the "ringing" and "connected"for zap channel

[Alchaemist]

Hi there,

        Basically, youare supposed to play arround with indications.conf
        To have the extensions configured with callprogress=yes but, be 
carefull because it is quite experimental.
        Also, what I did was to get an audio program (Cooledit, Adobe 
audition, or other), and you should use the spectral view (FFT Fast Fourier 
Transform), there you will be ableto see which frequencies the tones have, 
and their duration.

        Now, having said that.... I was half successfull in making it work, 
and I still have some problems, so if anybody else has a clear idea of what 
can be done, please shout in here ! :)


        Give a look to this:

        Particullaryl the section: Generating a Tone Set

        And this:

I have a TDM card in a asterisk machine.
I found that once I used it to call out, the call status changed to
"connected" even the callee is still ring.
How could asterisk distinguish the "ringing" and "connected" in zap channel?

thanks.
