[asterisk-users] Bad Echo between SIP calls

[Darryl Dunkin]

What are the end devices? That seems to have been lost here. The real
issue is the handsets as those are the devices introducing the echo (the
only analog players here). Most likely a volume or gain issue on those
handsets, what SIP devices are the echo issues between? If both people
hear echo, both devices are at fault, if one person hears it, it is the
other end at fault.

I like the way people replied to this message of mine.  It seems this
thread is going back to the hybrid echo issue(no this is not the
problem).   As said by many ZAP is not in picture for SIP--SIP ie
Ext-Ext internal calls.
 
To put my inputs I did tons of QA on this issue to ground on whats the
source.  Its not just the phone or only the network but may be both. I
am not sure how Asterisk would contribute to this.  At time for a given
2 internal extension there was no echo but suddenly turned up.  People
dialing on my phone have echo but not on other at the same time I have
few phones which I dial & no echo.  So ya dont know whats wrong.
 
Thanks all for your inputs & sharing ur experience.

	I don't see this listed anywhere here in the replies so.
	
	In your zapata.conf file try changing:
	echocancelwhenbridged=no
	
	to:
	echocancelwhenbridged=yes
