Multiple VPSs
More than one PBX in the network can have a VPS connected, and each VPS can provide voice mail
services for extensions connected to other PBXs in the network.
Conditions
• Hardware Requirement
The KX-TDA6920, KX-TDA0920 or KX-TDA5920 SD Memory Card for Software Upgrade to Enhanced
Version must be installed in the PBX connected to the VPS, and in all PBXs that will use this feature.
• All PBXs in the network must be KX-TDA-series PBXs.
• Only KX-TVA/KX-TVM series VPSs connected using DPT integration support this feature.
• Only extension numbers of 4 digits or less, using the Extension Number Method, are supported. (→
1.13.12 PRIVATE NETWORK FEATURES)
• Mailboxes for extensions connected to other PBXs in the network must be set up manually.
• An extension can receive Message Waiting notifications from multiple VPSs connected to PBXs in the
network. When multiple notifications of the number of unheard messages in an extension user's
message box are sent from different VPSs, the most recent notification will be displayed.
• A flexible button cannot be customized as a Message Waiting button for another extension at a different
PBX.
• Whether or not Enhanced QSIG information is transmitted can be set in the TIE table.
• When PBXs are connected by PRI23 cards, the card must be set to ISDN Standard mode. If set to T1
mode, the card must be removed and reinstalled to allow the mode to be changed. When the card is
reinserted into the PBX, it is possible to choose whether the card will be set to T1 mode or ISDN
Standard mode. The default is ISDN Standard.
• Transfer to Mailbox
It is possible to transfer calls to a mailbox of a VPS at another PBX, by creating a flexible button
containing the following:
[T] + extension number of VPS at other PBX + [P] + [#] + 6
Then, the extension user can transfer calls to a mailbox by pressing this key, entering the mailbox
number, and going on hook.
