[Freeswitch-users] example tone_detect to listen for dial tone and hang up?

[Nathan Neulinger]

Ah, maybe I wasn't clear enough - it's the other direction. i.e. Issue is with calls coming in from the analog side, not 
outbound. Symptom is that I wind up getting a 5 minute voicemail full of dial tone - usually from some stupid 
telemarketer call or other autodialer. I won't see any SIP messages since the ATA would be the one sending them.

Giving that tone_detect a try.

Thank you!
