AMD parameter for call progress analysis
The cp parameter specifies the actions to take when detecting call progress tones, overriding the default call progress analysis completion criteria CpComplete in the dialer.ini file. Application areas:
▪Calling countries with non-standard ringback or “number unobtainable” tones.
▪Calling networks that announce tariff information at the start of the call.
▪Calling subscribers with personalized ringback tones (music or announcements).
▪In order to achieve special effects, such as recording of in-band announcements.
The table below lists the different call progress events. Each event is identified by a letter; pre-CONNECT events in lower case, post-CONNECT in upper case. Each letter or group of letters is preceded by an action identifier (see the legend below the table). The post-CONNECT events are only detected in AMD filtering or calibration mode (amd=1 or amd=2).
Syntax
cp: actionID event... [ actionID event... ] ...
Default
cp:-b-c-d-f!r:t:v-B-C+D-F-T
Examples
cp:=vea
Ignore pre-CONNECT voice events (for instance, personalized ringback tones).
cp:*t*v
Record recfile when detecting tritone or start-of-voice (until stopped by noansw timeout).
cp:+v
Connect to extension when detecting start-of-voice.
