CapiFax is an ISDN-based network fax solution for 2 to 60 connections at one time. Each ISDN MSN/DDI (local number) can be configured for one network client so each workstation has a private number. Terminal server clients are also supported. Shamrock also has ISDN PCI cards for 8 (4 S0) or 30 (S2M) channels. The fax software can be combined with CapiCall on the same PC to share the ISDN channels as required. In combination with NetMail, a fax-to-mail and mail-to-fax gateway for unified messaging is also possible.
