Hello!<br>
<br>
We are not using headsets and speaker phones. Only standard
analog phones connected via Linksys or Audiocodes devices. I have
tested LG, Nortel, Samsung, Panasonic phones with same result. The
problem exists only _inside_ my network. So, for example:<br>
<br>
Audiocodes -- FreeSwitch -- Linksys ... echo present (often)<br>
Linksys -- FreeSwitch -- Linksys echo present (rarely)<br>
Audiocodes / Linksys -- Freeswitch -- Cisco 5350 -- PSTN (echo never
present)<br>
Audiocodes / Linksys -- FreeSwitch -- remote calling party over
internet (echo never present)<br>
<br>

I have tested many phone models with same result. So my
VOIP isn't<br>
properly functioning? Jeff, may You tell me what should I
double check<br>
to eliminate echo?<br>
