Preferred Line and Preferred Line Timeout
An Administrator or User can define a preferred line as well as a preferred timeout. If a preferred line is selected, after a
call ends (incoming or outgoing), the display switches back to the preferred line. Next time you go off-hook, you pickup
on the preferred line. You can specify the number of seconds it takes for the phone to switch back to the preferred line
using the “preferred timeout” parameter.
An Administrator can configure the “preferred line” and the “preferred timeout” parameters using the configuration
files or the Aastra Web UI. A User can configure these parameters using the Aastra Web UI only.
The following table provides the behavior of the preferred line focus feature with other features on the phone.
Configuring the Preferred Line and Preferred Line Timeout
You use the following procedures to configure the Preferred Line and the Preferred Line Timeout on the IP Phones.
Phone Feature Preferred Line Behavior
Call Return The phone switches back to the focused line immediately after the call ends.
Speeddial The line is already specified when the speeddial is created. The phone switches back immediately after the call ends.
Conference For incoming calls, the phone switches back immediately after the call ends.
Transfer For incoming or outgoing calls, the current behavior is that the same line used to transfer the call does not change. For incom-
ing calls, the phone switches back immediately after the call transfers.
BLF The phone switches back immediately after the call ends.
Park The phone switches back immediately after the call ends.
Voicemail The phone switches back immediately after the call ends.
Redial The phone switches back immediately after the call ends.
Dialing For incomplete dialing on a non-preferred line, the focus does not change if some digits are entered.
If no digits are entered or digits were cleared, the focus changes to preferred line after the time out has passed without activi-
ties.
Caller ID If the "Switch UI Focus To Ringing Line" parameter is disabled, the User is able to see the Caller ID when the phone switches the
focus to the ringing line.
Factory Default Factory default and recovery mode clears the "preferred line" and "preferred line timeout" parameters, and the phone operates
in a non-preferred line mode.
Notes:
• If you specify a value of “0” for the preferred line parameter, it disables the preferred line focus feature.
• If you specify a value of “0” for the preferred line timeout parameter, the phone returns the line to the preferred line
immediately.
