asterisk users - Mar 2006 - IAXY codec support and questions..

Hi..

I have to setup an extension in a remote location that will use a 
cordless analog telephone.. I am looking at the IAXY to do this for 
me..Basically the data path will be as follows...

[Asterisk] == (NAT) == {Internet} == (NAT) == ATA -- Handset

Since there are two NAT boxes in the path I know SIP won't work.. I also 
don't want to move the Asterisk box to the internet side of the NAT box, 
not only from the security perspective but also the potential issues 
with the already configured SIP phones that connect to it locally..

So as far as getting over the NAT problem the IAXY seems the way to go..

To save bandwidth I would like to stay away from using the G.711 
codecs.. Does the IAXY support GSM or iLBC? I couldn't find anything in 
the docs..

Thanks for any suggestions or input on this setup.. Also any reviews on 
the IAXY are welcome..

No. The IAXy only supports G.711 ulaw/alaw and ADPCM.

I don't know what 'docs' you were looking in, but this page:

http://www.digium.com/en/docs/S101I/IAXy.pdf

clearly states what is supported.

I have been evaluating the Iaxy and Asterisk for the company I currently
work for, and am rather impressed with them both. Once configured, the
Iaxy is a solid device--it's pretty much an appliance at that point
(plug it in, turn it on, and leave it alone).

My only gripe is the initial configuration, although even that isn't too
terribly bad. You must download and unpack a C program, then edit a
config file that the C program pushes to the Iaxy. If you want to change
settings on the Iaxy, you must reset it (press the "reset" button on
the
back, hold it for ten seconds, unplug the RJ-11, RJ-45 and power cables
from the Iaxy while holding the reset button, then replace the RJ-11,
RJ-45 and power cables) before you can push the new config to the Iaxy.

The Iaxy I am using is inside the same RFC-1918 network as my Asterisk
server (inside the NAT, that is), but I have used an IAX softphone from
inside another RFC-1918 network to place calls through my Asterisk
server, and that worked just fine, so I suspect the Iaxy would work just
fine through double NAT as well.
