[Freeswitch-users] Spandsp tone_detect segment frequencies

[Nandy Dagondon]

Hello everyone,

I'm trying to fine tune call progress tone using tone_detect_start. I set
spandsp.conf.xml:
<descriptions log-level="2">

Log shows these lines: Tone segment f1=-1, f2=-1, duration=336ms

How can I tell which frequency represents -1, 4 or 5?
What is the frequency assignment of silence?

Let's use North America as an example.
