Discussion: IAXy

I was quite intruiged by the IAXy, and recently deployed them in an install for the customer.

<p>Other than the lack of DNS support (which ruins dyndns-ability), I'm quite happy with the quality and performance of the units.

<p>One thing I found is that the iaxyprov tool was fairly primitive, although at least it was quite portable. It works for me, but isn't suitable for most customers to use in adding new IAXy's. The GTK one that Asterisk provides looks interesting, but a true hassle to build, especially on non-Linux platforms.

<p>There is a windows based provisioner which is quite good, but my last client is strictly a Mac shop.

<p>So I wrote my own provisioning tool; a single .C file, just like iaxyprov, which is its own web server and IAXYy provisioner. It seems to work quite well. I'm looking for people to beta test and stress test it for me before I post it publicly. Please contact me if you have any interest. It should work on any system (Mac, Linux, PC) and with any browser.

I have a similar problem.

• Linksys PAP2T
• Digium S101i iaxy

From the iaxy I can call the PAP2T and immediately I hear dialing, and the PAP2T phone also starts ringing immediately.
Doing this reverse, The PAP2T calls the iaxy and there is a pause for about 15 seconds before I hear dialing, and the iaxy phone never rings.

If I wait for the dialing (PAP2T calling iaxy) and if I pick up the iaxy phone the call is establish.
If I don't wait for the dialing, then all I get is a dialtone on the iaxy.

Anyone have a fix please email me, I'll be glad to update this section.

I have used IAXy as a Fax Extension. But fax machine gives me error "Comm. error", Is there anyone has working IAXy as Fax extension. Now I am using SPA3000 as Fax Extn which is working good.

Cheeeeers,

Just receiver a couple IAXy's from Digium, and they came with adapters rated:

Class 2 Transformer
P/N: XFMRWALL6VDC1A3.8MM
Input: AC 120V 60Hz 11W
Output: DC6V 1000mA
Model: RH41-0601000RU

Tip is positive.

As you can see, this is NOT a 9V adapter as others have received. I suspect that the circuitry in the IAXy is probably 3.3V, so the 6V adapter should be more than enough. The 9V adapter could also explain why people report the device running so hot. Mine runs warm, but definitely not hot. Obviously the FXS circuitry can tollerate the lower voltage, because mine is running just fine.

I also doubt you need a 1A adapter to run this too... but I haven't done any current measurements to verify that.

Here is a short linux script I developed for automatically re-provisioning the IAXy with the server IP when the server is on a dynamic IP service.

First of all, your server must be registered with a dynamic IP lookup provider. I use http://www.dyndns.org and run a script to keep my server (which is on DSL) properly updated. Therefore, I can navigate to http://myownservername.dyndns.org and always reach my machine.

The script simply executes a single ping to myownservername.dyndns.org to obtain the correct IP address. From there it uses that IP to rewrite the provisioning configuration file with SED, the command line editor. I have not set the program up on a cron job, but that's next.

The script requires a provisioning template file so that SED has something to edit with. That file is appropriately named ext210.conf.template and is written as follows:

• ;
• ; IAXY Provisioning description
• ;
• server: server_ip
• register

Notice that the provisioning file contains only the 'server:' directive and the 'register' directive. All the other directives for ip, netmask, gateway and so on have been eliminated since those should have been already set up, and therefore there is no need to retransmit them to the IAXy device. Removing parameters from this file seems to cause them to not be resent.

The script file that performs the update is as follows:

• ping -n -c 1 myownservername.dyndns.org | gawk '/64 bytes/ {print substr($4,1,index($4,":")-1)}' > myownservername.ip
• sed s/server_ip/`cat myownservername.ip`/ < ext210.conf.template > ext210.conf
• ./iaxyprov 192.168.1.7 ext210.conf

Notice this file contains only three lines... one to obtain and extract the IP address of the server, one to stuff the ip address into the extension configuration file and one to reprovision the device. Using gawk the IP numbers can be safely extracted from the ping result stream. Those numbers are written to the file 'myownservername.ip and must be in raw ip form (no parenthesis or other punctuation other than the dot seperators). The SED command (the second line) substitutes (s) at the location of the string to rewrite (server_ip) the contents of another file (cat myownservername.ip) using the input file (ext210.conf.template) and sending its output to another file (ext210.conf). Finally the provisioning command sends the new ext210.conf file to the iaxy device - assuming it knows its ip address.

The script is pretty simple and doesn't do any error checking - but, alas, this was just a one-nighter.

HTH

in iax.conf, put in notransfer=yes.

If the IAXY has an IP2022 inside how come we can't configure with a hostname instead of an IP address?

This page http://www.ubicom.com/news-and-events/20020916_UnivDevNetKit.html claims the IP2022 contains "ipDNSclient — Supports the Domain Name System, which associates names rather than numeric IP addresses for identifying devices on a network, and supports DNS lookups and dynamic DNS"

Wouldn't it be nice to provision our IAXY's with names instead of fixed IPs?

Windows IAXy Provisioning Application

This is a from-the-ground-up development of a means of provisioning IAXy devices using a Windows environment. For some users, being bound to Linux for IAXy provisioning is not viable or convenient in some cases. This application provides a GUI data entry for the various IAXy parameters and communicates the new parameters to the selected IAXy.

You are free to do with this application as you wish. It is provided as-is with the hope that it will make someone's day a little easier.

Revision Notes

1.01 Added subnet scan feature for Digium devices with 00:0F:D3 OUI MAC addresses. Note that this feature only works on Windows 2000/XP platforms--Windows 95/98/Me are not supported. This feature only works when the IAXy is on the same subnet as the machine performing the scan!

Hi there, I would appreciate any ideas on solving the following problem:

I have installed and configure Asterisk on White Box Linux along with
AMP. I have 2 ZyXel WiFi fones and two IAXy boxes to which I have
connected two regular analog non/electrical fones. The ZyXel fones and
call and receive to and from anybody; the IAXy connected fones can
only call to ZyXel fones; they do not receive any calls, or ring when
they get called. As a matter of fact, if I call them on one of the
ZyXel, I will hear the calling sound on the ZyXel, but the IAXy fone
does not ring and if I pick it up while it is being called I will get
a dial tone. I have provisioned the IAXy - obviously or I would be
able to use them as calling fones. Any ideas? Thanks in advance.

I tested it on S100I - working
