I have a proyect for a installation for 400 extensions using Asterisk… On this proyect, they also need to use aproximately 30 faxes.
I was thinking on integrate Asterisk with either Asterfax or Hylafax, and use a PRI circuit only for the faxes, but my customer wants to keep on using the analogic faxes.
Since FAXes are critical for this organization (some operations depend of them), I do not want to depend on ATAs to conect them to Asterisk. I can not have any risk of faxes being not receiving.
I though on using Digium Analogic Cards for the faxing, but since I would need a lot of cards, I am afraid of IRQ sharing problem and problems with so many cards on the motherboard.
I also though about analogic gateways, but If I use a 24FXS analogic gateway, that gateway is connected to asterik thought SIP, so I would have a small VoIP traffic segment where I am afraid of having again problems with faxes.
I do not known what approach to use… Any suggestion would be welcome.
