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

Grandstream GXW-4008
I'm trying to use a GXW-4008 for the first time to provide simple POTS. Is
anyone using it?
How about samples of SIP.CONF and EXTENSIONS.CONF?
Do you have advice for configuring the GXW-400x for this application?
How long a local loop will it support on the FXS ports?
When I started to configure the unit, I was able to connect via the WAN
port. Now I'm unable to connect to

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,

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

Asterisk t38modem Fax gateway evaluation
Hi,
I am trying to fix a Asterisk setup with buggy (POTS) Fax machines. The
setup consists of the following components:
- A Digium TE121 for connectiong to E1 ISDN
- Debian box with Asterisk 1.4
- Grandstream GXW-4008 SIP ATA to which the Fax machines connect
I am aware of the problems with this type of ISDN <-> Asterisk <-> SIP

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.

RES: GXW 4108 asterisk configuration
I have an Asterisk running with both GXW4008 (FXS) and GXW4108 (FXO).
The FXS Gateway works perfectly, no problem so far.
The FXO Gateway (GXW4108) also works fine. The configuration for local
settings in Brazil was quite easy, however, I still not able to make Caller
ID to work. I'm setting as DTMF Caller ID type, but still not working.
Let us know what kind of problem you have, maybe I

phones start ringing randomly with Grandstream GXW-40XX - solution!
Thought i would share this so it doesnt annoy others as much as it did me :)
If you recently installed a GXW 40XX and your extensions start ringing
magically now (ringing for no reason, pick it up its a clear tone) you
need to check the "Disable send MWI" in your gateway. apparently
certain old phones do not like the MWI signal and treat it like a ring
tone.

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.

Asterisk/GXW410x IP Analog Gateway
Hello All,
I am trying to setup a small system where Nextone Softswitch will send
traffic to Asterisk and then terminate on Grandstream GXW410x IP Analog
Gateway but for some odd reasons the call are flashed back from
Grandstream to Asterisk and creating a Black loop...

Intermitent voice issues
Hi all and thanks for reading.
I am experiencing a frustrating issue with asterisk where on some
calls the volume suddenly drops to inaudible o completely fades away
for a time. If you hold on long enough (20 to 30 seconds) the sound
will come back.
My asterisk server is on a public IP, and basically acts as a VoIP
bridge receiving calls from my customers (all of whom use Grandstream

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.

Missing audio
I have a FreePBX system with PRI trunks that's doing a number of things very
nicely, but frustrating me in one area.
I am using a Grandstream GXW-4008 in an off-premises location to provide
"POTS" service on four ports (this device worked fine in an early
application using a hardware VPN to the Asterisk server).
The Grandstream has a public static IP port, as does the

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

Transfer from Grandstream BT100?
Hi,
Does anybody know how to properly execute a transfer (without using the
|Tt option) from a GS100? Scenario:
1. I call from X-PRO (ext 1100) to Grandstream (1101).
2. Grandstream answers. Call is established.
3. Press [TRANSFER] on the Grandstream. X-PRO caller is put on hold.
Grandstream gets dial tone.
4. Grandstream dials 1103 (the extension of another GS100).
5. Grandstream hangs
