TDM2400P with echo canceller not working
Hi,
I have a box with Debian Sarge, Asterisk 1.2.1 (and zaptel 1.2.1) and a
TDM2400P with echo canceller. I installed the card but no echo
cancellation is being made...seems like the echo canceller module does
not work, infact the software cancellation is working.
My zapata.conf has echocancel = 128 and echocancelwhenbridged = yes but
no echotraining parameter which gives a warning.

Help! Echo problem even at T1 PRI?
Hello,
We have an asterisk setup at our client's site using a TE205P. The line to
telco is a 23 channels T1 PRI, however the line has random echo problems
(about 5-10% of the calls)!
Can anybody tell me if echo cancellation is really needed even at a T1 PRI
to the telco? Because people keep saying when they deploy voip solution in
Hong Kong using T1 PRI, there is no need of echo cancellation.

Weird Echo Problem
Ok I know I'm not the only one having echo problem with asterisk but the
weird thing is that when I receive a call from a PSTN line on my TDM04B
card I don't have any echo problem at the beginning of the call then
after a few minutes I start having echo on my side only (the person
calling from a regular phone doesn't have any echo), then it stop and
come back all the way until the

Echo on Zaptel FXO :(
Hi All,
I've got an MD3200 modem which is working as a Zaptel FXO interface for
Asterisk (X100P clone I believe). It seems to work, but on incoming or
outgoing calls I can hear the other party ok but when I speak, I hear
my voice echo back at me (quite quietly but it's distracting!) on
everything I say. The other party doesn't seem to hear the echo - they
just say I sound a bit quiet.

Bad ECHO problem after upgrade to HEAD version
I installed the HEAD version of Asterisk on January 24 and ever since then I have a really bad echo problem.
I have tried to go back to the stable version, but it won't install.
Anyone else having this trouble? Suggestions?
Thanks,
Brian
Here are what I believe to be the pertinent details of ZAPATA.CONF.

SIP phones unbeatable echo
Hey all again, I'm wrestling with echo problems on our sip extensions. I've
set these items in zapata.conf but tweaking these values doesn't seem to
make much difference
echocancel=yes
echocancelwhenbridged=yes
echotraining=2500
rxgain=8.0
txgain=1.0
are there other settings that can help me tame this beast? Been searching
but not turning up anything that'll work here.
Thanks

Echo worse after new echo patch
Hi all,
I was excited to see the announcement on the list regarding the fix for
the echo problems on Digium FXO cards!
I have 2 X101P's, TDM400P with 4 FXS modules and couple of XLite
softphones. A few months back,I had gone thru the recommendation on the
list to remove echo from the SIP phones(I never did have any echo on the
TDM400P FXS phones), and had removed about 90% of the echo.

Tiny Echo on PSTN via Zaptel
I'm using Asterisk 1.0.9, a Digium TE210P dual T1 card, and two Rhino
channel banks (one 12FXO/12FXS, the other 24 FXS). So it's an analog
phone on the inside connected to one of the FXS ports, and PSTN line
connected to one of the FXO ports.
My problem is that as soon as I hear the _first_ ring when I dial out
through the PSTN line, I hear a tiny echo on the phone (I estimate

Channelized T1, SIP phones, HW Echo Canceller
I have a channelized T1 coming in from our telco, terminated onto a TE405.
There are three channelbanks serving internal analog extensions, and about
10 Cisco 7960s.
I have no reports of echo on the analog extensions (as expected). The
7960 users complain of occasional echo (seems like 1 in 5 calls). Only
the SIP user hears the echo, not the caller.
I have echocancel=yes, echotraining=yes,

Some echo?
I have a 12 channel PRI with SNOM 190's and asterisk CVS from January.
Most calls are fine, all incoming calls are fine, but I am getting
echo on a significant number of outgoing calls.
The person on the other side hears a perfect call, but the SIPphone
side gets to hear themselves.
It happens 100% of the time to some numbers (outgoing only), and only
sporadically to others.

echo / delay problem
I'm having with an echo or delay
I connect to the PSTN with a x100p and then connect a std. phone
to a FXS module on a TDM10B.
The std phone is only 2-wire so I know this is not helping.

I have tried many echocancel values. The best thing to help was

Weird..bridging to Zap channel FXS instead of bridging to PSTN FXO on outgoing group
Hi All,
Channels 25-28 on a customers PBX are regular Zaptel FXO cards that
are hooked into 4 incomming phone lines. They are all in a group to do
automatic rollover for outgoing calls (if channel 25 is being used,
dial on channel 26, etc.).
Sometimes when a user is dialing a number, instead of bridging to one
of the FXO cards it goes and rings to Zap/1-1.
This doesnt occur all the time but some

EADS6550 and asterisk - echo on PSTN call
Hi list,
would like to know if some of you have tested asterisk connected to an
EADS 6550 analogique PBX (also know as Nexpan50).
Our set up is a Dell Optiplex with 1 TDM400 4 FXO, 1 TDM400 4 FXS, (no
other card, each of them have their own IRQ) all ports connected to the
EADS. We have GS ATA286 as EP. Calling from ATA to ATA give a perfect
sound. Calling to PSTN numbers or reverse side,

X100P echo problems - seem to be fixed now
For those that have had X100P echo problems, it seems that somewhere just
prior to Asterisk CVS-12/04/03-14:24:40 it has been fixed to where its hardly
detectable for just a couple of seconds at the start of a call. (I use to
have it rather bad for the first 15 seconds or so.)

echotraining on T1 circuits
Hello,
We just had some new T1s turned up today to replace others that our contract
has run out on and we are now getting more echo on the new T1 lines than we
had on the old ones.
The T1 type is 24-channel, D4/AMI SF Robbed-bit(the same as the T1s they
replaced)
The problem is that we are getting echo on about 10% of the calls in and out
placed on these new T1s compared to less than 1% with

Echo on one E1 line, but not the other
We're rolling out Cisco 7940 phones, linked to *, which is running a TE405p
EuroISDN.
We have 2 ISDN lines, one we had for testing, and one for general (40+
users) use.
During the testing phase, we had 10 phones linked to the second ISDN line,
and there were no problems with echo at all. Lucky me. However, since we
have started rolling out, we've had quite loud complaints that there is
