[asterisk-dev] dsp programming

[Dmitry Andrianov]

I guess you want to detect ringback tone, right?
Asterisk already can do it on Zap (DAHDI) channels - look for callprogress and progzone parameters in the Zapata.conf. (Be aware that progzone can have only five possible values:

        us
        ca
        cr
        br
        uk

check main/dsp.c for details and implementation.

Hi, all
I am new to dsp programming.

I set up call through AMI originate, and detect that phone is ringing or not i.e

action: originate
channel: zap/1/666
exten: 667
context: test
priority: 1

when i originate call on 666 , chek that number is ringing or not.

I want to use this facility in autodial feature to detect on ring transfer.
