Indicator updates
Digital telephone indicators reflect the current status of the telephone. For
example, they identify when calls are waiting, active, or on hold, or, if your
office has voice mail, that messages have been received.
Indicators are updated as follows:
„
by the host PBX when a connection between the host PBX and Remote
Gateway 9150 unit is active
„
by the Remote Gateway 9150 unit for feature keys defined on stations with
local call capability
Host-controlled indicator updates
Indicators for host-controlled features are updated automatically by the host
PBX each time:
„
an incoming call is received by your site from the host PBX
„
an outgoing call is made from your site through the host PBX
„
a message waiting indicator (MWI) update is received by someone at your
site
Note: If the PSTN is being used and the Remote Gateway 9150 unit is
configured with a permanent (always on) connection to the host PBX, the ISDN
BRI service is active and telephone indicators are always updated.
If the IP network is being used to route calls, indicators are always updated.
