Moony

Moony is an ISDN call monitor program. The basic purpose is to show the phone number (and names) for incoming calls. Other highlights are telephone answering machine, fax (send and receive), SMS notification, speech output and network support.
The display of calls is done in a call history window and in a small popup window which is shown while the call comes in, but which does not interrupt you when you are typing text. It supports multiple phone numbers (MSNs), multiple answering machines, SMS notification for missed calls, lists of known callers (to show the name instead of the phone numbers) and area code recognition (display of caller's city/country).
