Best FXO Gateway
I'm currently looking to deploy an Asterisk server using an FXO media
gateway to connect to the PSTN and was looking for any user experiences that
may aid in selecting a gateway. Specifically i'm looking for a 4-port model
under 500 dollars.

Grandstream GXW-4108 8 port FXO
Has anyone used either the 8 port or 4 port FXO device from
Grandstream? (GXW-4108 or 4104).
They seem to be the lowest cost multi port FXO devices that I can
find, so I'm getting ready to buy the 8 port version. I just want to
see if there are any opinions on the device before I commit to the
purchase.
If people have not used the Grandstream, are there any issues with

FXS to SIP gateway
Hello list !
I don't have the money to test out all the products and reading the
manuals is not always that enlightening...
Does someone here know a good gateway-product that lets analogue
telephones communicate with an Asterisk-server.
I have found the Grandstream GXW-400x to be able to add SIP-accounts to
analogue telephone devices that are connected to the FXS-ports. Moreover

Hey everybody,
Is it alright to run two TDM400s on the same machine? If it is, how would
one differentiate between the channels on each card? So, if I'm running
strait FXS and my first card is fxsks 1-4, would the second be fxsks 5-8?
Would there be any interrupt problems?
Any help would be great!
Thanks!

ATA phones ring when they register
Hi,
I have an 8-port Grandstream GXW-4008 V1.2A ATA
converter with analog phones connected to it.
They work fine except for just one "feature" I would
like to modify. Somehow, each time the ATA
re-registers the SIP clients or each time the device
has to be rebooted for maintenance, the phones ring
once. This feature can be useful as it notifies the
user of the re-registration.

Please some enlightment on ENUM !!
Hello all you Gurus out there!
Please could you explain something to me:
Currently I try to get ENUMLOOKUP() working. Naturally I do all the
testing with my own number.
I registered my number at e164.org
I paid for registration of my number at a registration agent for e164.arpa
(I know, I don't need both. I just did the .arpa registration first and
later discoverd the free .org service....)

TDM400P FXO click sounds
Hello,
I have a TDM400P with 4 FXO ports, currently using three. When sending or
receiving calls on this card, there is a nearly constant
popping/clicking sound, it is related to the
echo cancellation?. I adjusted my gains properly, but to no avail. I
even found that setting echotraining=no in zapata.conf didn't change the
scenario at all. I've plugged analog handsets into the

Dial problem
HI,
I have 2 TDM400s plugged in a PC. I failed to use same channels to
make a call to PSTN. It shows it can't establish connection after
dial command issued. Below is the log. Actually, the call is
established as I can hear voice from the called party but the
softphone is still showing ringing. It seems the TDM card can't get
an answered signal from PSTN. After 15 seconds, the call

Native bridging analog phones trouble DAHDI channels.
I own a TDM2400 board, with three FXO modules and one FXS.
I'am having trouble with analog sip phones, from two different
equipment. (Grandstream GXW-4024 192.168.0.105, and Audiocodes MP202),
sometimes when I am calling someone, then I press flash, and then call
someone else, both calls stay connected after I hang up.

Grandstream RS-232 config (slightly off-topic)
I realize this may be slightly off-topic but I'm wondering if someone here can lend me a hand.
One of my GXW4008 has gone "unconfigurable" via standard HTTP (refuses connection) and I can't use the built-in IVR because I had previously disabled the "keypad update" feature. So I'm stuck with just telnet, the reset button and RS-232.
Telnet commands are very limited

Grandstream GXW-4104 ???
How well does the Grandstream GXW-4104 or (8) work w/Asterisk? I would use a Cisco Switch w/FXO Ports but that would be a little "Pricy"
I Can't use a Digium FXO Card, as the asterisk Server is offsite.
Thanks,

XFS and CentOS 4.3
Hi All, after looking around for info on XFS(the filesystem) and its use
on CentOS and/or RHEL 4. There seems to be a lot of noise about 4K
Stacks (especially on linux-xfs at oss.sgi.com).
So what is the best way to get XFS working with CentOS 4.3 ? And not
have something like this happening.

Hello everyone! I'm planning on setting up a new system shortly and
can't pick the right card... We will have 2 or 3 lines coming in and

I need the Sangoma A20200 or even the A20200D (Echo cancelation)...
I was thinking I'd use a Dell 2.0 GHz machine as the server... If

Digium TDM400P vs Sangoma A200 for 2 x FXO
Evening all.
I'm looking at building an Asterisk system for one
of the projects of the Charity where I'm the
SysAdmin.
The project has two analogue phone lines - BT
Featureline Compact, we're in the UK - that I'd
like Asterisk to handle.
My current quandary is which FXO interface to use.
I've been looking at the Digium TDM400P and
Sangoma A200, which are similar prices for
