Hi Duane,
It is true that transcoding is an issue for this little devices.
Here's the transcoding output from my asterisk running on a Linksys
NSLU2 (ARM 266Mhz/32M):
CLI> show translation
Translation times between formats (in milliseconds) for one
second of data
Source Format (Rows) Destination Format (Columns)

I enabled speex just to see how it will perform. According to the
output is should be able to handle a call (didn't tested tough). I
tested gsm/g711 transcoding and it is working fine.
Asterisk 1.4 is able to handle properly g729 in pass through mode,
however, voicemail for a call with g729 _only_ will not work.
Voicemail is working quite nice (even the mailing option).
And here's the amount of memory available on the device:
$ free
total used free shared buffers cached
Mem: 30520 27180 3340 0 2296 13800
-/+ buffers/cache: 11084 19436
Swap: 0 0 0
There are ppl using the gmail plugin with these little devices.
I'm running asterisk on this little device (behind a NAT) for almost
two years without a problem.

Ovidiu Sas
