Hello all, I have been trying to evaluate whether our next IVR project should be on Windows+Dialogic or Asterisk+Digium.
We will be connecting behind a Nortel M1 PBX. In terms of the hardware, it seems that for Asterisk all I need is something like the relatively inexpensive (<$1,000) Digium T1 card. Whereas for Windows, I would need a Dialogic card with T1 AND DSP (about $5,000 as far as I can tell)
It seems to be a no brainer - Asterisk wins.
The IVR functionality we need is
- play voice file
- detect DTMF (very reliably)
- Originate call
- Record voice file
My question is, can the DSP functionality that is on the Dialogic card, really be done by the host machine CPU (3GHz, 1GB in standard servers these days) ?
I am sure it can do it for some channels, but can it do it for 24 ? Can it do it comfortably for 8 channels ?
Thanks and all the best
