Outgoing call process
To place outgoing calls, users can either pick up the handset on the telephone or
press the line key. For a detailed description of the outgoing call process, refer to
the sample illustrations beginning on page 38.
Incoming call process
When someone places a call through the host PBX to a Digital Telephone IP
Adapter unit, the RLC connects to the remote unit. The host PBX then
completes the call normally. If the RLC cannot establish a connection, the call
rings until the host PBX forwards the call to voice mail. Refer to Chapter 6,
“Using the digital telephone”, for a more detailed description of the incoming
call process.
Note: After a power failure, a Digital Telephone Internal or External IP Adapter
unit comes back online and answers all incoming calls. To prevent the unit from
staying online indefinitely after a power outage, enter a single Offline command
in the unit's Online/Offline table for the week. Use SPRE codes to go online and
offline. For more information on the Online/Offline table, refer to “Online/
Offline Table” on page 50. For more information on SPRE codes, refer to
“Going online and offline” on page 152.
Host-controlled call mode
When you place a call to someone at the host site, or when someone from the
host site calls you, the call is in host-controlled call mode. Calls in host-
controlled mode are routed through the host PBX. Refer to the sample
illustrations beginning on page 38.
