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.
(yes I have read the 2-wire 4-wire issue)
I have tried many echocancel values. The best thing to help was
rxgain and txgain. below is my current zapata.conf file
All help would be grateful. I have tried

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.

Help! Zap echo on bridged calls
I've been going nuts lately trying to get rid of an annoying echo
problem that makes my asterisk server unusable when clients try to call me.
Here's the breakdown of the issue - Hoping that someone can throw me a
clue:
My setup is as such:
Single AMD Athon machine with X100P clone card and voip through multiple
providers .

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.)
I'm using DECHO_CAN_MARK2 with KFLAGS+=-DAGGRESSIVE_SUPPRESSOR and

Call waiting on X100P
I have Asterisk setup in a SOHO environment.
I have 2 X100P cards at Zap/1 and Zap/2.
I have 1 TDM400P card with Zap/3 - Zap/5.
I have subscribed to callwaiting, callerid and calleridcallwaiting from
Qwest on the 2 PSTN lines - Zap/1 and Zap/2.
My problem is when I'm in an active call to the outside thru Zap/1 or
Zap/2, I can't pickup the incoming callwaiting call. I can see the

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.

Very bad echo (appears that...)
The echo canceller algorithms aren't doing anything. We get extreme
echo during the conversation, it appears even before the call connects,
the echo is there...
This only happens with SIP to/from WCFXO (analog POTS). Looking at the
Zaptel configuration:
/etc/asterisk/zapata.conf:
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.8

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

Echo cancellation
Hi Everybody,
Got a weird problem here I think. Got a setup with an asterisk (current
from cvs as of a few hours ago) in a box with an el-cheapo ISDN BRI card
connected to the PSTN network and two Snom phones internally (one Snom-100
and one Snom-200). Dialing between the snom phones or dialing out to PSTN
from any of the snom phones works perfectly.
But when I receive a call FROM the PSTN

Buzzing on TDM400P FXS?
I have an intermittent problem with the one FXS line that I have. On
most calls, the first ~5 seconds of the call has a loud buzzing noise
on the line. After 5 seconds or so, it fades off to nothing, and the
sound quality is great. Searching for "buzzing" on the list doesn't
give a whole lot to work with. The buzzing happens on calls that are
routed over both my FXO line and

echo problem
I have searched for how to locate echo cancelation on SIP clients, but
cant find anything and echocancel=y doesnt seem to have any effect.
Configuration:
CVS-HEAD from last month
iPAQ h5500 with SJPhone (gsm/ulaw/alaw)
Problem description:
When I place or receive a call I hear a faint delayed echo of myself.
The other party hears a really bad nonmuted echo that makes the call
unusable.

X100P Configs for Australia
Hi,
Just wondering if anyone else in Australia is using the X100P to connect to
the PSTN, and what configs they have for it?
I'm finding at present when I make a call I get a fair bit of echo of myself
speaking, and also the person on the other end can't hear me very well
(perhaps need to up the digial Tx Gain? I don't have it configured at
present)
