[Freeswitch-users] Does I need jitter buffer

[Boris Kovalenko]

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)
