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 too old, it haven't been updated recently (I'm talking about the original ixj driver) and Quicknet don't offer good Linux support.
If you prefer to use hardware based DSP I think that it will be better to use not a PC cards, but to find some SIP based VoIP Gateways (they have g729 and g723 codecs included) and are working very well with Asterisk.
I'm recommending you this web site http://www.voip-info.org it's a very good VoIP information resource.

Hi All,
Is it correct to say that by design, asterisk wont make use of any cards hardware dsp capabilities ?
I don't think that any of the hardware cards currently supported
have any dsp capabilities, but I wanted to know if for example,
in the future a driver was written for a card that did have dsp capabilities,
would asterisk be able to make any use of it ?
I am only just starting out with asterisk, and have not fully understood
the architecture yet, but it seems that in order to handle VoIP and PSTN
seamlessly, all dsp related functionality has to be handled by software ????
Thanks Shahed
