I am contemplating migrating all our phones over from a legacy PBX to a Asterisk-based installation. There are three fax machines currently used daily through the legacy PBX, which is fed by an ISDN30 line.
My current thoughts were to a Digium or Sangoma PRI card to manage all incoming calls, forwarding all voice calls to their relevant SIP extensions based on DDI’s. If a call is incoming with a fax DDI the idea is to route that via a seperate Digium analogue card, e.g. TDM400P with three FXS modules, which in turn are connected to the fax machines.
Does this sound like a reasonable and more importantly reliable solution?
Any thoughts are appreciated
