Now the SLA station is ready to use. The following functions can be achieved by this configuration:
•
Making an outbound call from the station/extension, using LINE key
When the extension is in idle state, pressing the line key for this extension on the phone to off hook. Then
dial the station's extension number, in our example, dial 3000 or 3001 on the configured Phone to hear the
dial tone. Then the users are able to dial external number for the outbound call.
•
Making an outbound call from the station/extension, using BLF key
When the extension is in idle state, pressing the MPK and users could dial external numbers directly.
•
Answering call using LINE key
When the station is ringing, pressing the LINE key to answer the incoming call.
•
Barging-in active call using BLF key
When there is an active call between an SLA station and an external number using the SLA trunk, other
SLA stations monitoring the same trunk could join the call by pressing the BLF key if "Barge Allowed" is
enabled for the analog trunk.
•
Hold/Resume using BLF key
If the external line is previously put on hold by an SLA station, another station that monitors the same SLA
trunk could resume the call by pressing the BLF key if "Hold Access" is set to "open" on the analog trunk
and the SLA station.
