Panasonic KX-NCP500 Features Manual page 397

•
All PBXs in the network must be KX-NCP series, KX-TDE series, or KX-TDA series PBXs. For information
on the hardware requirements for KX-TDA series PBXs that share the same VPS, refer to the
corresponding Feature Guide.
•
Only KX-TVM series VPSs connected using DPT integration support this feature.
•
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 customised 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.
•
PBX Code Method
The number used in this method must be no more than 8 digits.
•
When using a mailbox number containing more than 5 digits, the version of the KX-TVM series VPS must
be 2.1 (Main Software Version 2.50) or later.
•
The VM Menu feature cannot be used in a Centralised Voice Mail network. When extensions belonging to
a PBX that is not connected to the VPS have a mailbox in the VPS, the VM Menu feature should be disabled
for the mailbox using the Class of Service (COS) setting of the VPS. Otherwise, there may be an answering
delay of about 6 seconds.
•
To use Centralised Voice Mail over an IP network, the network should consist of only V-IPGW cards or
only IP-GW cards.
[Voice Mail (VM) Transfer Button]
•
A flexible button can be customised as the VM Transfer button with the floating extension number of the
VM group of a remote VPS as the parameter.
•
A call in progress can be transferred to a VPS mailbox by pressing the VM Transfer button and then (1)
pressing a DSS button or NDSS button, or (2) dialling the desired extension number directly. When the
desired extension number (or TIE Line Access number + PBX code + desired extension number) is dialled
directly, it must be followed by "#" in these cases:
–
The extension user performing the transfer and the destination extension belong to different PBXs.
–
The PBX of the extension user pressing the VM Transfer button does not have its own VPS.
•
VM Transfer button functions will not operate on networks using Common Extension Numbering for 2 PBXs,
or Common Extension Numbering for Multiple PBXs. It is necessary to create a network where the Voice
Mail can be accessed by the TIE Line Access number or an Other PBX Extension number.
