asterisk users - Mar 2008 - ADPCM codec and IAXy device

Hi All;

I need to buy one IAXy device, but I discovered that
it supports only g711 and ADPCM codec, so I was wonder
that it does not support g729 or GSM?!

Anyway, what is that ADPCM and how much it consumes
bandwitdh? Also, asterisk support such codec? What its
name in the configuration?

Any advise?
Regards
Bilal

I've heard, and I think Eric Wieling just confirmed it on the mailing 
list today, "The IAXy does not support highly compressed codecs..."

I seem to recall that there's a space for ADPCM in the IAXy provisioning 
file, but I also seem to remember that this codec was not implemented in 
the IAXy's firmware. 

I've never tested it, so I don't know for sure.  And if this was true, 
of course it could have changed by now :)
