[Asterisk-Users] How to decrease Asterisk load

[Wiley Siler]

It is not that they are not working with Asterisk... It is that there
are none available.

Go check out the link that was sent to you before... Here it is
again....
http://www.zapatatelephony.org/

As you can see, Zapata (which drives Asterisk) was originally designed
to be a chipless DSP solution.
All the functions of a DSP without the need for specialized equipment.
Plain old x86 doing the functions of DSP.

So that is why there are no cards with DSP for Asterisk.  It was
designed to not need them.
The fact that new cards are getting DSPs now is just due to the fact
that * servers are being loaded so much now that offloading echo
cancellation and such to a DSP should allow for higher capacity systems
across the board.  Of ccourse, being vaporware, we have not even seen if
it will be that much of a benefit.

Cheers,
W

Should I believe that at this time there is no DSP capable cards working
with Asterisk?

As yet !
As for digium cards latest cvs commits suggest that there is some
ongoing development on hardware based echo cancelation and dtmf
detection. So its just a matter of time.
