<div>Hmm, this may work. Does it generate a
channel variable once complete?<br>
<br>
Also, I see hits a counted in frames. What are the units? 20 ms
frame or something else?<br>

<div>Clarification:<br>
<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><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>
