[Freeswitch-users] Help with tone detection

[Jean-Marc Hyppolite]

Hello everyone,

 

Is it possible to have some help in setting up mod_spandsp for call progress
tone detection? I have not been successful thus far. I keep getting an
"error reading frame" message like this one below.

My spandsp.conf.xml file:
