[Freeswitch-users] Subject: Re: Tone detection issue

[Nandy Dagondon]

Hi Alex,

Referring to this wiki:

https://wiki.freeswitch.org/wiki/Mod_spandsp#Call_Progress

You need to tune the detector (record the tone and make a freq analysis).
Take note the series of <element /> in spandsp.conf.  That's the sequence
of tones to be detected. The min/max is the duration of every tone.

In the dialplan app start_tone_detect, the data=1 refers to the <descriptor
name="1">. You can create your own set of progress tones.

Good luck.
