What is and is not VoiceChange?

VoiceChange is an open system, by means of which various voice applications can be created, e.g.

intelligent phone answering machine
automatic switch operator
automatic customer support line
automatic information line including the fax-on-demand option

and many others. Scripts implementing the functionality of an intelligent phone answering machine are supplied with standard installation of VoiceChange. Sample scripts of some other functions are included on the installation CD together with documentation.

VoiceChange as intelligent phone answering machine

Standard installation of VoiceChange provides a phone answering machine for each of your phone lines. This function is enabled only if your phone exchange supports the following two functions:

Automatic call forwarding when the line called is busy or the called subscriber does not answer the phone.
Passing the information about the call forwarding by means of DTMF (as in FaxChange) or passing the information by means of TAPI interface (being prepared, made-to-order for the time being.

VoiceChange will collect the forwarded call, playback the personal greeting for the called line and record the message. The program will save the said message in the VoiceChange server archive and send it to the owner of the given line by e-mail.

For MS Exchange Server and Lotus Notes, VoiceChange searches the line owner in the e-mail system directory. Which menas that the only administration is entering the phone numbers in global directory. In SMTP/POP3 version the administrator has to enter the phone numbers into the special database of VoiceChange system.

You may listen to his voice message directly from the e-mail form delivered to your mailbox. If your PC is not equipped with a sound card or if you are not present in the office at the moment, you may collect the voice messages by phone by calling the “collection line” You can use this line to change your personal greeting; moreover, the administrator can change the company greeting. Access to the collection line is protected by personal password.

VoiceChange Administration

VoiceChange administration is very simple.

In MS Exchange version the administrator adjusts the user setting in the Active Directory Users and Computers program. Installation of VoiceChange creates new "VoiceChange" tab appearing in properties of each user.
Voice message archive is saved in filesystem, into VxArch share on the VoiceChange computer. Each user has its own directory, in which each message is saved as one file. NTFS access rights to files are set up so that VoiceChange and the user, to whom the given message belongs, may handle only the specific file.

In Lotus Notes VoiceChange version the situation is more complex. With regard to "email" licenses it was not possible to modify the standard user database and thus VoiceChange creates its own database. Users lists are transferred to the database by distribution agents. The agents also enable the command "add this user to VoiceChange database" in the Notes user database. User setting is then adjusted in VoiceChange database.
Voice message archive is saved in Notes database. Access rights are set to each message so that its owner may work only with the specific message (and the VoiceChange system, of course).

Regardless of the e-mail system, the VoiceChange administrator has the following tools available:

UmsMonitor is the program showing the actual condition of VoiceChange–what is happening on each line, what was the last completed event.
UmsInfo lists the information about the installed Datasys UMS family products. This information is necessary e.g. for technical support request.
UmsTaskCfg configures the setup of VoiceChange process administrator (for details see How does VoiceChange works?).

VoiceChange programming and extension

VoiceChange is very flexible. Its functionality is determined by the script written in the Visual Basic Script language Functions of VoiceChange core (COM objects or VBS libraries) are called from this script. You can adjust the VBS script and thus modify the VoiceChange function.
