Hey pjsip list, I have been spending the past day trying to find a suitable and tested embedded platform (w/a proper evaluation board including audio) for a 2 channel VoIP gateway running pjsip. It doesn't seem like there is any "out of the box" solution; only hints about what may work. If anyone can point me to a working, verified evaluation board for pjsip - I would be very grateful. Below are the options I've seen so far. There seem to be two strong contenders: AD's Blackfin (uClinux only) and Atmel's AT91SAM9 (uClinux or linux). The Blackfin support is listed in the pjsip documentation<http://www.pjsip.org/sip_media_features.htm> as "underway" but Benny Prijono had a few blog posts explaining how to start working with the Blackfin BF-537 STAMP and AD1836AZ-DBRD audio daughterboard - but no followup as to whether this works, how many channels and performance numbers. The SAM9, has a lot more buzz around it (relatively...). Quite a few forum posts have people asking questions regarding various stages of debugging. The only problem is finding a proper evaluation platform. Atmel's offerings only support an input channel on the higher end SAM9M10-G45-EK<http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4735&category_id=163&family_id=605&subfamily_id=1739> (the other EK's only have a DAC), and that too is single channel. Hope is found when looking at 3rd party evaluation kits on the at91 website, such as Ronetix's AT91SAM9261 starter kit<http://www.at91.com/component/resource/article/Tools/35-Kits%20&%20Modules/1106-starter-kit-with-atmel-at91sam9261.html>. However, it doesn't seem like anyone has run pjsip on this platform yet. The pjsip trac shows <http://trac.pjsip.org/repos/wiki/PJMEDIA-MIPS> performance figures for the Olimex SAM9-L9260 board, but doesn't say which CODEC daughterboard is used. In addition to that, Olimex has something very close<http://www.olimex.com/dev/lpc-h3131.html>based on an NXP ARM9 device, but it does not have ethernet. D'oh! Other options: Beagleboard w/linphone: Seems to be somewhat tested and easy to deploy. The downside is it is only 1 channel and based on the fairly expensive TI DaVinci. Audiocodes AC48x CPE VoIP Toolkit: All in one, but probably very expensive M53281KIT: Freescale's Coldfire with 3rd party CODECs. Also probably expensive I might also try getting this to work on an MPC875 platform I have laying around (running @ 50MHz), outputting PCM via a transparent SCC. Again, any pointers regarding evaluation platforms would be great. Eran -------------- next part -------------- An HTML attachment was scrubbed...
