Hello! Would You please explain does I need jitter or not? As I wrote about a month ago I offten have an echo when calling local_user -- freeswitch -- localuser. And _never_ have an echo when calling local_user -- freeswitch -- remote_gateway. My local network is gigabit based. remote_gateway is on internet. Will the jitter help me and what settings should I start from? -- Regards, Boris
Its not possible to have echo in a pure VOIP (properly functioning) implementation. The only source of echo would be from acoustic echo on your phones which is most likely what you are experiencing. A Jitter buffer wont help this problem. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Does-I-need-jitter-buffer-tp70...

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

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)

The analog phones are a common cause of echo. Look for settings on the device to use an echo canceler. On Tue, Dec 6, 2011 at 8:58 PM, Boris Kovalenko <boris@tagnet.ru> wrote:
