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
Dear Shahed,

Hi Shahed,
yes you are right if you use Digium hardware all dsp related
functionality has to be handled by software.
Asterisk supports also other hardware and one of them have DSP on it -
Quicknet Phone/LineJACK cards ... but I'm NOT recommending you to use
this hardware!
Quicknet's driver is
Dear Shahed,
We are in process to done hardware DSP device for coding of G.729,
G.723, GSM and other speech codecs. We will support the drivers for
Asterisk, SER and OpenH323. The device will be available at middle of
next year. There are 6 variants of the device:
- USB with 16, 32 and
Hi All,
Is it correct to say that by design, asterisk wont make use of any cards
