Possible embedded platforms for a VoIP gateway - an initial summary of findingsEran

Hi there, I am in the process of testing pjsip on a SAM9260 board. I have
done preliminary tests on the AT91SAM9260-EK from atmel  The problem is that
you only have a audio out device so the media side does not work, as stated
by Eran, But currently with linux (Openembedded, Angstrom) installed, it is
a very nice platform to work with, And I had no problems getting pjsua and
other applications to run.

You do get an add on board for this with the TLV320AIC23 audio codec,
Calypso board( example implementation:
http://www.ethernut.de/en/documents/sam-web-radio.html ) I have not tested
this myself, but you can still get them from some sources it seems.



Our own board was designed similar to evaluation board but with the LM4549
Codec on board, will be able to test new hardware within the next week.



Regards



Gideon Spreeth
