[Asterisk-Users] Hardware based DSP

[Shahed]

Thank you all for your explanations related to my question.

I have one follow-up question though.

When I said that all dsp related stuff has to be handled
by software within asterisk, I was thinking of
conferencing at the time.

I mean in order to be able to conference a sip session with
a PSTN call, it would have to be handled by software, even
if both the channels had hardware dsp capabilities. Right ??

If you are dealing with just a single channel, then the driver
may handle codec/echo cancelation stuff with hardware help (??)

As an aside, what is the best way to go about learnig about
the aritecture of asterisk, other than "using the source" ??

The Wiki pages are great, but I have not (yet) found any info
about asterisks architecture itself (in depth that is).

Some linked websites / blogs provide good info on some topics,
but is there a good high level design doc available anywhere ?

It would stop people like me asking so many basic questions in
the -dev list.

Thanks
