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

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