The High Performance Echo Canceller (HPEC)
I recently read about the following new technologies from Digium. Has
anyone tried the new HPEC or knows when it will be available?
TDM800P and HPEC
The TDM800P is an 8-port analog telephony interface card, so it fills the
gap between Digium's 4-port and 24-port cards. Analog phones and POTS lines
are going to be with us for some time, and demand for support for them
remains high. The

DAHDI aaaaaaaaaaaaaaarrrrrrrrrghhhhhhhhh :((((
The information (or lack of it) on upgrading from zaptel to that
@&*^QW%&^%!!! dahdi is very frustrating.
I cannot find anything on how to uninstall zaptel, i found an earlier post
to this list which suggested make uninstall and make remove in the zaptel
directory which just generates errors and does nothing (on zaptel 12.1).
Then i install dahdi-linux and dahdi-tools and i want to

Asterisk 1.8.x Skips DTMF Digits on a First DAHDI Initiated Call
Hi,
I know it sounds weird, and this is part of the reason I have not
reported that sooner. As I upgraded from 1.6.2.x to 1.8.x several
months ago I am experiencing this problem. If a call is initiated from
a DAHDI extension after no DAHDI extensions were used for some time,
arbitrary DTMF digits are skipped and the call fails. If the call is
redialed it goes through. Normally just one (1)

Hi,
I'm using a revision 6822-enabled Dahdi-Tools (see
https://issues.asterisk.org/view.php?id=13897) with a Junghanns QuadBRI.
1. Do I still need qozap driver ? If positive, how is it recommended to get

2. Which line should be included in /etc/dahdi/modules to have the
appropriate driver loaded ?
3. The process I'm planning to use is :

Digium PRI and Echo cancellation
Hello,
I would like to double check what Echo Cancellation my Digium Card uses.
I thought I bought the little more expensive card that integrates
EchoCancellation. How can I check?

Junghanns QuadBRi not really recognized in Dahdi
Hi,
I'm using Asterisk 1.6.1.18 with latest Dahdi Linux and Tools (rev 8854) and
libpri 1.4.10.2.
During installation, I'm facing this :

Of course, I've got span descriptions in /etc/dahdi/genconf_parameters :

Echo problem in the analoge lines

2) If I am getting a message in the consol that unable to enable the echo cancelator, then what does it means? The hardware is not supporting echo

Is using dahdi_genconf_parameters recommended to configure dahdi ?
Hi,
I've just discovered that dahdi_genconf could create configuration files
reading a single genconf_parameter file.
1. Is using dahdi_genconf recommended to configure dahdi or is it a helpful
tool for specific devices or installation processes ?
2. If not, is there a custom mecanism that would prevent hand-edited files
to be written over by dahdi_genconf (you can obviously remove

dahdi-channels.conf -v- chan_dahdi.conf
Some recent issues I had with hardware seem to come back to not
understanding two very similarly named files:
/etc/asterisk/dahdi-channels.conf
/etc/asterisk/chan_dahdi.conf
I've modified the chan_dahdi.conf to work now, but it would appear all I
needed to do was include dahdi-channels.conf in chan_dahdi.conf and the
problem would not have persisted? Is it me or is that a bit Monty
Python?

Problem routing call to fax machine on DAHDI FXS port
I am running Asterisk 1.6.2.17.2 with a Openvox A400 card with 2FXO/2FXS
modules. I'm trying to set-up things to route analog fax calls from a
FXO port to an analog fax machine on a FXS port on the same card.
Outgoing faxes work just fine. But incoming faces are routed to the
right DAHDI extension, but the call dropped right as the fax machine
rings for the first time. The fax machine

Zaptel -> DAHDI: now echo
Hello
I have upgraded our asterisk box from zaptel to dhadi two weeks ago...
Since, there has been quite a significant amount of echo when making a
call. Only for the local outgoing call, the person on the other side
doesn't hear any echo.
This is with a TE-110P ISDN PRI card ..
I've pretty much took the original zaptel configuration and used it

Problem getting TDM400P clone card to go off-hook and dial
I am having problems getting a Nicherons TDM400P wildcard clone to dial out.
Everything appears to be configured correctly, but although I see call
progress, it never seems to actually pick up the phone.
(The following is a test of 911 emergency, where I substitute 811 [repair
service] as the actual number dialed.)
