    <div>Hmm, this may work. Does it generate a

                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&#39;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 &quot;got the sucker!&quot;<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>
