_________________________________________________________________________Clarification:
No need to measure RTP quality. Just need to detect when a test tone changes into white noise or dead air.
I see mod_spandsp can fire events on tone detection. Is there a way to do inverse? That is, fire event on tone loss?

The only issue, how to measure the RTP quality in real time.

Subject: [Freeswitch-users] Help needed with audio test setup
Hello Community,
The problem is that a 3-rd party SIP hardware causes audio isssues in
less then 1% of the cases. Need to do 100's of manual test calls to
identify it and bring to the vendor.
Is there a quick recepie to make the following FS test setup? Should be
as simple as possible. If someone has something ready-made to offer,
please contact me off-list.
Here is the idea:
-FS generates test SIP call and keeps it up for N minutes.
-One side initates the call and sends test tone at X Hz
-another side (also FS) answers the call and sends test tone at Y Hz
-both sides listen to the tone coming from the other side.
-If tone in either direction degrades into siginificant noise or
silence, FS leaves the call up indifentely long AND sends email
notification "got the sucker!"
-If in N minutes tone in both directions did not degrade, FS hangs up
the test call and initates a new one. Infinite testing cycle until we
turn it off.
Thank you,
Victor
