[Explanation]
Extension 201 does not answer the outside call, so the call is forwarded to the VPS, and answered by
mailbox 201. If the outside caller leaves a message, the VPS sends a Message Waiting notification to the
extension using Enhanced QSIG information over the private network.
When forwarding the call, PBX-2 sends any received call information (Caller ID number/name, etc.) along
with the VM trunk group number to use, applicable time mode, and extension number and forwarding reason
of the original destination extension to PBX-1 as Enhanced QSIG information.
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

• All PBXs in the network must be KX-TDA-series PBXs.
