[Freeswitch-users] Tone detection How To

[Nandy Dagondon]

Ah ... you'd like to have a call progress detection.

I used spandsp.  First, you have to analyze the tones to get the freqs.
Define and configure the frequencies in
conf/autoload_configs/spandsp.conf.xml. In my case, I define <descriptor
name="63">

In your dialplan (ex. outbound), include the ff lines before the bridge app:

<action application="set" data="bridge_pre_execute_bleg_app=tone_detect"/>
<action application="set" data="bridge_pre_execute_bleg_data=63"/>  <!--
the descriptor name -->

For an inbound call, do the same but change bleg to aleg.

I hope it works with your setup. Cheers!
