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.
