CallServer - Version 3.1 CallServer is an ISDN Calling Monitor including a time scheduled answering machine and telephony feature for Windows 95/98/NT. Your PC is logging all telephone calls. The caller ID and the alias name is notified on incoming calls. The included answering machine makes you reachable any time. You can configure the answering machine to be active on default times where you are not in. And more - it’s possible to playback different announcements depending on daytime. These announcements can be configured individual for every caller in the caller list or every telephone line. The telephony feature lets you make a phone call out of the program. If your telephone provider supports the necessary service all charges for outgoing calls will be displayed by the CallServer. You need an ISDN Card with installed 32Bit Capi Interface (CAPI2032.DLL) and a full duplex soundcard.
