[asterisk-users] Echo problem in VoIP-calls

[Danny Nicholas]

The "harm" in any of these settings is environmentally controlled.  What
"does no harm" in one setup can be a deal breaker on a smaller machine or
slightly different technology. How harmful or harmless jbenable is depends
on your hardware and what your other settings are.

Will turning off the jitter buffer affect the quality of the other calls ??

jbenable = no

I must say I'm not really into these jitter-settings in asterisk. I made
jbenable=yes as "it can do no harm"...

Try the SIP phone. If it is better then you might try looking to see if 
there are any echo cancelation settings on the softphone or analogue 
adapter you can change. Try turning echo cancelation off aswell since if 
there are two running they can interfere with each other and make the 
situation worse.
 
If you hear echo on that phone then it might be that the network 
connection from that location has a higher latency making the echo far 
more noticeable.
If the other party you are connecting to hears echo then this could be 
down to the phone or the jitter buffer. If you start with a small jitter 
buffer the echo cancelation will train to that but if you get increased 
jitter the buffer will grow and add an additional delay to the audio. 
Often echo cancelation only trains at the start of a call.
Maybe try disabling the jitter buffer.
