Dahdi_dummy is more accurate than core timer?
Hi,
I have some servers that are dedicated to do meetme conferencing. From
some previous test i concluded that I need to use dahdi_dummy as it is
more accurate.
If I did use the core timers in dahdi (not loading dahdi_dummy) I got
bad quality in the conferences and dahdi_test showed 99.6% as worst.
I thought maybe the issue as bad hardware for the timing or something
else. But today I

One PRI card with 2 (or more) Telcos
Hi list!
We currently have a PRI gateway composed by a box with two Digium quad-span
PRI cards (a TE420 and a ).
One of the cards is filled with TELCO1, while the other has first two slots
filled with TELCO2, and 3rd slot with TELCO3.
I am currently having (timer ?) issues on TELCO3 (span 7)
D-Chan (202 as determined by dahdi_genconf ) is constantly failing causing
on-going calls to terminate.

Fax and dial-up connection issues
I have a pretty large setup on one of my customers. Digium TE420B (with echo cancelling module), 3 Xorcom Astribanks with 32 FXS each and 1 Xorcom Astribank with 16 FXO. These FXO ports are NOT used for fax/data transmission, as they are connected to cell phones. Not really related to the issue, but there are also 250 SIP phones.
The problem is that fax and dial-up connections are really

Asterisk 11.24.1 garbled audio
Hi all
I am using asterisk 11.24.1 on a centos 5 machine. kernel 2.6.18 flavor.
(x86_64).
I have about SIP 150 endpoints on it.
when I send a message I'm getting garbled audio.
I used to have a single PRI card in the box - but something happened and
that connection
no longer worked. I removed the card and also removed the system.conf and
chan_dahdi entries.

debian/dahdi/zaphfc - Unable to receive TEI from network!
Hello,
The harddisk of my etch/bristuffed asterisk1.2 box finally died. I moved
the cheap (1397:2bd0) HFC-S card to a squeeze host (i686) and built
dahdi modules 2.3.0.1 using m-a. After zaptel->dahdi and asterisk
1.2->1.6 config adaptations, everything seems ok, except for the BRI
side, unable to bring layers 1/2 up.

problems inserting dahdi modules using Debian Leni
Hi. I have a Debian Leni system with asterisk-1.8. I was trying to
get meetme to work and it depends on dahdi, so I compiled dahdi-trunk
and dahdi-tools-trunk, however, when trying to insert dahdi_dummy, it
complained about symbol crc_ccitt_table, although the module was
actually there in the kernel tree. So, I took the Debian source, and I
had the config and I did make Bzimage, make modules

dahdi_test drops after restarting Sangoma driver
Hi,
Does anybody have an idea as to why dahdi_test results drop to
unacceptable levels after doing a wanrouter stop/start using a Sangoma
card? See below that it drops from 99.99% to 98.55%:

MixMonitor - garbled/corrupted WAV files
Hi,
I've had problems with MixMonitor recordings. A lot (I'd say almost 50%) of
those are corrupted (can`t be opened) or garbled. That is on only one
server, which is using the same Asterisk version (1.6.2.18) as the other
servers which are mostly fine.
What can be the cause? The conversation themselves are reportedly of good
quality, only the recording is a problem.

Dahdi - Meetme problem on a VM
Hi,
I am running Fedora 7 VM. On an earlier configuration with zaptel and
Asterisk 1.4.21 , meetme worked alright. I upgraded to Dahdi and Asterisk
1.4.26, and the result is choppy sound via Meeme, while a simple Musiconhold
works OK with descent audio quality. So I am sure its a Dahdi_dummy problem.
Running dahdi_test gave me very poor results.

DAHDI Question/Choppy Sound
Hi!
I have Asterisk 1.6.1 installed on OpenSuSE 11.0 running with choppy sound.
One specialist on the forums asked me if I have DAHDI configured, he assumed
that this could be cause of choppy sound problem.

Do I need to configure DAHDI even if I do not have any Zaptel devices?
Is there any guide for configuring

TDM-400P alternatives?
Are there any other relatively low cost analog cards available? I'm interested in finding something that might work a bit more reliably than the TDM-400P....

TDM 400P in Malaysia
Hey,
We are deploying an Asterisk machine in Malaysia for a client. The
machine has a TDM400P with 2 x FXO & 2 x FXS. I'm wondering if there are
any Malaysian users out there who might be able to help me out with a
running zap config for their phone system.
Cheers,

Terrible dahdi_test results
Hello, I am trying to get a Wildcard TE110P to work in a relatively

TDM-400P Sound Quality issues
I'm running a TDM-400P with 2 x FXS and 2 x FXO. I'm finding that there seems to be an odd relationship to sound quality on the card to my local when connecting via a SIP client.
When I'm on my local network, if I connect to Asterisk via a SIP client (such as x-pro), and dial an outside line through the card, sound quality seems quite good.
However, when I'm at a remote
