<p class="MsoNormal"><font face="Times New Roman" size="2"><span style="font-size: 10pt;">I have quite a number of users complaining that when they are using
handsfree to talk over a landline, the other end can't hear them. It's
like the person is speaking 5 feet away and can barely hear their voice.
However between internal SIP calls, it's fine.<br>
<br>
What could be the problem?</span></font></p>
