TDM400P, fxotune and ADSL filters - Just a FYI, FWIW
This may be commonly known but I haven't come across it so here goes,
maybe it'll help someone:
I have terrible echo with asterisk 1.2, zaptel 1.2.12, and a TDM400P
with 1 FXS and two FXO modules.
The Mark2 echo canceller with Aggressive turned on was the only setting
that would make it acceptable.
I found fxotune with this zaptel version to be broken.
I pulled the latest fxotune.c

fill input buffer - got -1 bytes, expected 4000 bytes Failure! when I
run it. This is a new install of Asterisk 1.4 and zaptel 1.4. Also I

TDM analog cards, volume, echo, fxotune, ztmonitor and HPEC
Hi, everyone:
I am developing a system using Asterisk, TDM-400 analog cards, analog
lines, and Polycom SIP phones for internal extensions.
Initially there was bad echo but after a series of efforts, I've managed
to reduce it to a negligible level (it only happens when both parties
speak simultaneously, and even there, only for a few hundred
milliseconds). From an echo standpoint, things are

FXOTUNE update
Hey all,
First of all, some background:
Fxotune is a utility that is used to tune the hybrid on FXO modules
For all of you with FXO modules out there, fxotune can help you adjust
the analog and digital hybrid that is on the FXO interface and tune it
so that it maximizes echo return loss. This means that it will reduce
your default echo which is received, and will help any echo cancellers

Well, I have a big problem with Asterisk, my problem is that when I'm in a

Help with fxotune
What does fxotune need to do its job correctly - complete silence on the
line, or just absence of the dial tone? For how long? I've been trying
to get a silent termination number out of my telco all morning and have
come up empty. When I just dial "1" as some online guides suggest to
break the dial tone, it is silent for a few seconds, then plays a "Your

Odd results from fxotune?
I recently ran fxotune against our incoming PSTN lines to try and help
with some echo problems.
It produced the following fxotune.conf file:
2=8,253,2,244,255,10,244,3,253
3=4,0,0,0,0,0,0,0,0
4=4,0,0,0,0,0,0,0,0
I'm a bit surprised by all of the '0's for channels 3&4, esp. given that
it's populated values for channel 2.
Is this considered 'normal' behaviour, or

Fun with Echo -- Follow up
I figured I'd answer my own thread and document what it took to get
rid of the echo at my location. For those of you trying to get rid
of echo, let me tell you, "what worked for that guy, probably won't
work for you". I think we've all heard that before, and it's true.
Let me assure you that echo can be removed from your phone lines. At

TDM-400, Polycom SIP phones, and echo problems
Hi:
I am working on a new system with a TDM-400P card with three FXO modules
and one FXS module.
The system has been in place for a week. Users are complaining of echo
problems. I have noticed this echo myself. It varies in severity. It is
sometimes bad enough to make it difficult to converse, but the users
find it generally unacceptable. They miss their old phones, which just
worked. As you can

WCTDM-24xxp woes
I am currently running Asterisk 1.2.8, on an AMD Sempron 3100+ (ASUS K8N
Nforce based board). I am using a Digium wctdm24xxp to terminate 8 (2x
quad) FXO lines. Using ztmonitor (From zapata) I cannot see that there is
any registerable incoming volume from these lines. I've been running them
at rxgain = 25 (zapata.conf) to make the audio audible, however this
creates poor call quality issues

ztdummy compile again
Hi,
I'm still strugling with getting an easy to use conference system
implemented. I did have app_conference running, but today I upgraded
asterisk to 1.0.9 and it stopped working. I've tried following the
instructions for compiling app_conference on 1.0.7 but it didn't work.
So I went back to ztdummy (I've not had any luck getting this to compile
on FC2).
Anyhoo, I've

HPEC audio clipping
I have recently moved an asterisk system to a new location. This location
is experiencing terrible echo. I installed the HPEC from Digium but that
has caused a new problem.
When HPEC is enabled and more that 16 taps are used, the audio from the
outside caller gets clipped. Instead of hearing:
Hello, my name is Mike
one hears
He o, m ame ike
If the taps are set to less than 16, there
