VOICE MAILBOX, EXTERNAL
Definition
An external PC based voice server, e.g.
DiscoVoice 5000, can be connected to ASB 150 02.
An analogue extension board is used for connection.
Signalling utilises DTMF.
Use
An external voice server can be used for several
applications.
Below is described solely how a peripheral voice
storage system can be connected to ASB 150 02.
For functionality regarding the connected voice
system, see user guide for the peripheral equipment.
An extension user can divert calls from her/his
telephone to her/his voice mailbox.
On arrival of an incoming call to the extension, the
system will divert the call to the directory number of
the PBX-Group to which the peripheral voice mailbox
is connected.
Using DTMF, the system will then also transmit the
called extension's directory number.
In this manner the caller gains connection to the
extension's mailbox.
Operation
System Telephones
Indication that message is waiting
When a message exists in the voice mailbox, the lamp
of the programmed key lights and flashes rapidly.
Retrieving from the voice mailbox
A call is initiated by pressing the programmed key.
If all connections are busy, busy tone will be heard.
When the last stored message in the mailbox has been
erased, the relevant lamp on the telephone
extinguishes.
Message waiting indication within a CN
The feature CN ’message waiting indication’ is based
on the usage of ISDN supplementary service UUS for
supporting proprietary CN functionalities in
ASB15002.
The usage of a centralised voice mailbox is based on
the proprietary CN services line identification and call
diversion.
The centralised voice mailbox can only be located in
an ASB 501 node.

Capacity / Limitatons
The capacity of the voice storage unit and the number
of concurrent connections is determined on the basis
of the prerequisites for the voice storage system.
ASB 150 02 must possess the same number of
analogue extension positions as number of ports in the
voice storage system.
