ShareISDN will help you share the functions of an ISDN card with other users within your network. For example, each employee of a company can send faxes or transfer files through a single ISDN card (one is not required for each one), and thus we will save money (on cards) and time and effort (when installing them ).
You will only have to install the ShareISDN server (SISsetup.exe) on the computer that has the ISDN card, and the ShareISDN client (SICsetup.exe) is each PC from which we want to access that card. From now on, you can use any application that has support for the CAPI 2.0 protocol, which is the standard programming interface for ISDN cards.
You can free download ShareISDN 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
