Hello! 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: Audiocodes -- FreeSwitch -- Linksys ... echo present (often) Linksys -- FreeSwitch -- Linksys echo present (rarely) Audiocodes / Linksys -- Freeswitch -- Cisco 5350 -- PSTN (echo never present) Audiocodes / Linksys -- FreeSwitch -- remote calling party over internet (echo never present)
Headsets, speaker phones, calling a remote party over high latency.
