Software for Opensource 16e1/t1 Telecom card

it would take lot if time to develop all the stacks mentioned below either we can consider existing open source stacks or 3rd party commercial options like aricent , ccpu or netbricks  which could help in faster roll out


some parts are patented(audio and video codecs)  and can never be made open source such parts we have to think on how to get the tie up

SS7 :  MTP1/2/3 , ISUP , TCAP, MAP , INAP , CAMEL 

sigtran : M2UA , M3UA

ISDN : euro ISDN

3G-H324M :  compliant to existing 3gpp protocols


Driver : channel driver to integrate various open source call manager , HDLC

Audio Codecs : G711 , echo cancellation , DTMF , G729 , G723

Video Codecs : H264 , H263

we are mentioning all the areas of effort , later it will be easy to distribute between interested contributors

Low cost and High quality Telecom Hardware

It’s time to rethink on available open source telecom hardware, available ones are just not enough for current need ……

To list few I have tried with various variants of zaptel which are just a dumb card and leaves lot of load on various call managers like asterisk or free switch….. But thanks to all who initiated and contributed to its development.

Is it possible to build a open source carrier grade (preferably with 16e1s) card with a good communication processor and a DSP to support  on board media processing  for both audio and video under  500 USD ?

Yes it is possible ………………………………….and

is it possible to build a quality  card which is better than today's dialogics or PT or Telesoft of the worlds
yes it is possible.
