hi ..
i have the exact same problem you have
..
seems to be related to Budgettone phones in my
prob.
I *tried* selling an asterisk exchange to a
client
and today he phoned telling me he is very
unsatisfied
& I risk being thrown out .. suggestions would
be
welcome! i've tried *everything* that has gone
in your correspondence on the list, and a
few
of my own .. no luck! seems a hardware
problem.
arghhh!!!
the other budgettone problem is it won't do a
consultative transfer ie. you answer an incoming
call,
speak to someone else on a different extension
and then pass the call .. only way I have found
to
"emulate" that is using call parking which is
VERY
messy!!
well ..
maybe it's consoling to know you are not
alone!
cheers,
Dave

Hello,

I get no echo on mine.. but you can check to make sure your line isn't
reversed. A reverse wired jack can do that.
I don't think
so but I have tested reversed and it doesn't solve my echo
problem

Subject: [Asterisk-Users] SIP and ECHO
Hello,
I have read the information on echo and SIP in the FAQ and I have
scoured the mailing list for possible solutions, but as yet I have not
been able to get rid of this echo.
I have a Sip phone, Digium 4 Port FXS, and 3 Digium FXO cards installed
into an asterisk server. If I call between the Sip Phone
(Budgettone-100) and the 4 FXS ports everything sounds great. If I call
out to the PSTN through the FXO cards I get horrible echo, I have even
been able when talking loud enough to get a horrible feedback loop
going. I have tried 4 different echo cancellers in the Makefile for the
Zap drivers and nonoe of them changed the situation.
I have echocancel = (Any where from 1 - 256, I have tried alot of
different values), and I have echocanelwhenbridged = yes.I only hear the
echo start when the call gets bridged onto the outgoing PSTN lines.
Is there anything I can do?

Hi,
For me:
rxgain=0.8
txgain=0.8
in zapata conf do the trick.
Now the echo is allmost inexistant. Maybe the sound is not very strong but
the quality is very good.
I have the default echo canceller (no modification in the source files).
Tested with a lot of SIP phones (ATA (G.711), X-Lite(GSM), SJ_phone(G.711),
Cisco 79x0) and one X100P card.
BR,
Dan
