asterisk 1.4.X, T.38 and NAT
Hi,
I have been trying to get T.38 to work with clients behind NAT for the past week but with no success.
I have an asterisk server on the public internet and several Grandstream (I tried Linksys too) HT502 ATAs behind NAT in different locations.
I tried every possible combination of NAT, canreinvite, t38pt_usertpsource entries, I even tried asterisk 1.4.19, 1.4.24.1, 1.4.25 all with the same

TE121B server recommendation
Hello,
If anyone is using a TE121B card and it works reliably (i.e. no "HDLC
Bad FCS" or similar errors), could you pass along the make, model, and
basic configuration of your Asterisk server?
We tried upgrading our old Dell PowerEdge server to a SuperMicro system,
but that didn't help. I would like a solid recommendation before I
suggest another purchase.
Thanks.

Asterisk w/ Nokia "e" Series Handsets
Anyone using Nokia "E" Series handsets with Asterisk? I'm trying to
deploy some e71's and am having an issue. I can get a single handset
working, but when I try to create a SIP profile on the second phone, it
won't allow me to save the profile, saying that devices in the same
"realm" must have identical username and password.
Anyone have a workaround for this

Looking for a good lightweight Linux softPhone
I used to use IDEFISK, but since it was taken over/renamed into Zoiper
it's been really hard work - now I'm told that they won't support my
chosen distribution - Debian Etch - the current stable version of Debian I
prefer.
So, looking to dump Zoiper and go with something else - I want something
light-weigh (So that rules out Ekiga - and Zoiper was going down the

T.38 fax solution, opinions?
Hi,
I'm putting together a fax solution for my company that utilizes T.38. I
wanted to throw out my plan and get some feedback if anyone is doing
something similar or sees a blatant problem with it.
We're currently rolling out SPA-942 phones for the standard desk phone with
vanilla Asterisk 1.4.15 (just upgraded it today) on the back end. Most calls
for satellite offices are handled by

looking for a better ATA
I currently us Linksys/Ciscio, Grandstream and AudioCodes ata's. none of
the three perform well in all enviroments. Between stablity issues, T38 and
DTMF talkoff all three suffer some combination of issues.
I am looking at Patton and Innomedia. Has any one tried either brand and
what is your experience with them. Which would be the base for stability,

Small site survivability
We are currently moving away from a wide-spread Cisco CallManager deployment
to Asterisk. For many of our small sites we have the routers configured for
what Cisco calls SRST so if we have a WAN failure, the router acts as a SCCP
registrar. We are converting to SIP, and from what I can tell Cisco wants a
license for each router to run SRST over SIP...
So my question to the group is: What are

Asterisk Fax
Hi
I know that this topic was on the list maybe dozen of times. But I
have a question regarding the fax support in asterisk, because all the
information I could get does not give me the clear view of if. I read
that Asterisk 1.8 will have strong fax (t.38) support, but I want to
know if these four scenarios will be possible to achieve:

Converting Cisco 7961 to SIP
As part of a project to move a clients Cisco phones to SIP to work with an Avaya system, I'm taking a Cisco 7961 we bought and adding it to our Asterisk setup. Now, I've gotten the firmware files from the site, the latest version is 8.4 which contains the following files:

How to set up Fax on Asterisk - Using analog Fax machines and HT502 (or FXS of a Digium TDM410P)
Hello Asterisk users,
We are having MANY but MANY problems configuring an analog fax machine to
work properly on Asterisk, the first thing we do was to plug in the Fax
analog machine to the FXS port of the Digium TDM410P, we set echocancel=no
on zapata.conf and also faxdetect=yes on general section, but our Asterisk
CRASH every time we try to send/receive fax!
We are using Asterisk 1.4.21 and

Anyone know of a pass through ATA
Anyone know of a company that makes a pass through ATA?
By pass through I mean have an Ethernet switch built into the ATA, like most
desktop phones have.
All of the dual ethernet ATA's I have seen have WAN/LAN ports, not two LAN
ports.
I fooled around with DMZ etc...but it just doesn't work as well.

Questions about asterisk and spa2102
Hi there! First mail on the list :)
1.- is it possible to use an spa2102 to make and revice calls from a
"normal" phone? I mean, I know I can use it to connect an analog to an
asterisk server, but I want to know if it can be used to connect
asterisk to the analog phoneline.
2.- I'm trying to unlock the spa2102 with no succes at the moment, any

MWI not working on most ATAs in Asterisk 1.6.2.17
We've had several customers report since upgrading them to our new
Asterisk 1.6.2.17 server (from version 1.4), that their MWI no longer
works. No significant changes have been made to their SIP
configuration, nor to their ATA configuration.
While not exhaustive, these are the ATAs that don't work:
Linksys SPA2102
Linksys PAP2T-3.1.15

Heist of MagicJack SIP credentials?
While I myself am not a MagicJack user, I'm curious as to whether anyone
here has managed to heist their MagicJack account's sip credentials, and
use them to terminate calls using asterisk. Apparently it's as simple
as sniffing the SIP credentials. If so, said person would enjoy
unlimited termination for $20 year while retaining the flexibility of
setting their CallerID to a

WellTech 380x Gateway
Ok this is a simple question...
What has been your experience with the WellTech 38xx series (I'm looking
specifically at the 3802)
VoIP gateway? I'm looking for a good (and hopefully not too expensive)
VoIP/T.38 gateway for my office.
Asterisk intergration is not a major factor at this time but may be
later on. How well does it work? Is Echo
a problem? Do the T.38 capablities

Asterisk distributed deployment

Fax, T38 and NAT
Gentlemen,
I have 3 faxes attached to an Asterisk. Fax - SPA2102 - Asterisk.
0851711201 and 0851711290 is on our WAN, no NAT.
0197673581 is outside our WAN and needs to be NAT'ed.
Sending a fax from 0851711201 to 0851711290, no problem, switches to T38
and fax goes through.
Sending a from 0197673581 to 0851711201, no problem as long as i dont
enable T38 on 0197673581.
But, if i enable T38

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.
