ISDNCid is a CAPI-based
ISDN application with Caller Id and Answering Machine capabilities. Unwanted
callers may even be blocked. It stays in the system tray and pops up (if
configured to) showing incoming calls. The answering machine may be setup
with answering delay and max recording time. If your ISDN adapter supports
it you may even receive FAX's. When registering you have to fill in your
first (primary / MSN1) phone number excactly as shown in the MSN or register
dialog box. Do not include long distance codes, spaces or non-numerical
characters unless shown in the MSN1 field.
