stage for a concert. During the concert the bass player had his iPhone on top
of his amp. Everytime the iPhone received data the amp made a horrible noise.
If I have my data correct, the cause was the bass player’s iPhone was GSM.<o:p></o:p></span></p>

<p class=MsoNormal><span style='color:#1F497D'>There is/was an issue where certain
cell phones, when placed too close to a 7960/40 would cause the ip phone to
make some noise. I don’t recall if it was a pop or not, but it was an odd
sound. There was no solution but to move the cell phone farther away from the
ip phone.<o:p></o:p></span></p>

<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Recently a few of my old 7960s have been making a periodic
pop noise, like it does when it is powered on with POE. This happens when the
phone is only idle.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am going to replace these, as the users report them, since
they are EOL. Anyone have any experience on this?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks,<o:p></o:p></p>
