Network fax software for Windows

CapiFax runs with all 32-bit and 64-bit Windows versions, including Windows Server 2003 and 2008/R2. Suitable ISDN adapters, depending on the OS and the required channels, are e.g. AVM-Fritz PCI or -USB (2 channels), Primux 1/2/4 S0 (2 to 8 channels) or Primux S2M (30 channels, requires CapiFax S2M). Alternatively a fax-enabled ISDN router can be used, e.g. models from Lancom or Bintec.

For VOIP you may use the ISDN outlet of your internet router like AVM Fritz!Box 7490, Telekom Speedport 921V or a PBX with internal ISDN lines. Or you use the VOIP-CAPI for dirtect SIP support. Or you use the VOIP-CAPI for direct SIP support.

Clients: Each person or division can have a private fax number (MSN/DDI). For transmitted fax documents a private outgoing number is possible. Automatic printing of received and/or transmitted faxes is supported. Besides normal network workstations, even terminal server clients can be used.

Fax to mail: Depending on the called number or the caller’s number you can easily define if and to which address received faxes are forwarded by e-mail as PDF or TIF attachment, e.g. to Microsoft Exchange or any other SMTP server.

Mail zu Fax: In combination with NetMail you can create a system, which can handle mails like by converting attached files like PDF. Associated programs for PDF, DOCX or similar must be installed. You get a confirmation mail after the fax is sent.

Fax polling: Offer multiple documents for fax polling, one per number (MSN/DDI). In addition it is also possible to deliver different documents depending on the CLIP number or fax ID of the caller, e.g. for offering regional information based on area codes or countries. Fax polling documents can quickly be created using the fax printer driver.
