color:#1F497D'>Echo is always an analog issue. That’s not to say it can’t be an
issue with an IP Phone since they have DSPs that convert analog signals into
digital ones, however if you haven’t changed IP Phone firmware recently, they
are probably not the issue. If you have, you can try and revert back and see
what happens. You can check if you users experience it on their headset or
handsets or both.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>I would suggest you probably need to focus on your analog components
like the GW. Has anything changed there? Newer IOS loads contain new DSP loads
for the DSPs on the GW which will affect their operation. You can open a TAC
case for some troubleshooting, but I suspect you might need to get a call into
your SP at some point.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif"'>Here
is a little problem for all. Over the last week or two, several users
have stated that they are experiencing echoing( hearing their voices) when
they are on the phone. When I checked these extension I am hearing any
echoing. The users have been advised to verify whether or not these calls
are from land line or cell phone. They reported back both.
What other in-depth troubleshooting method can I apply</span><o:p></o:p></p>
