Note
• If the correct lines are not online, make sure the correct PBX type is selected, that the PBX is
properly programmed for APT/DPT Integration, and that the PBX and VPS are connected by
4-conductor cables.
7. To test the connection, dial the extension number of the VPS from a telephone connected to the PBX. If
the VPS answers, the APT/DPT connection has been established.
IMPORTANT
Important information for KX-TA users (except KX-TA1232):
When 2 VPSs are connected to a KX-TA series PBX, the following procedures should be performed to
make the VPSs function correctly.
1. Delete a mailbox in either VPS so that each extension has only one mailbox.
After Quick Setup is complete, each extension has a mailbox in both VPS 1 and VPS 2, however, each
extension should have only 1 mailbox.
2. Match extension settings with subscriber settings.
For each subscriber’s extension, make sure that the destination for Call Forwarding and Voice Mail Transfer
is the extension number of the VPS that contains the subscriber’s mailbox.
For example (see diagram below), if jack 06 (extension 106) has its mailbox in VPS 1, assign extension
107 or 108 as the destination, not extension 115 or 116.
3. Make sure that the extension numbers of VPS 1 are 107 and 108, and the extension numbers of VPS 2
are 115 and 116.
