Description and More Information
Provides a method to control EEE functions on personal computer port and switch port
by enabling or disabling EEE. The feature controls both type of ports individually. The
default value is Enabled.
Provides a configurable port range (2048 to 65535) for Real-Time Transport Protocol
(RTP) and secure Real-Time Transport Protocol (sRTP).
The default RTP and sRTP port range is 16384 to 32764.
You configure the RTP and sRTP port range in the SIP Profile.
Allows users to connect two calls to each other without remaining on the line.
Allows a user to transfer an active call to an available directed call park number that the
user dials or speed dials. A Call Park BLF button indicates whether a directed call park
number is occupied and provides speed-dial access to the directed call park number.
If you implement Directed Call Park, avoid configuring the Park softkey. This
Note
prevents users from confusing the two Call Park features.
Allows users to hear different ring types depending on whether the call was originated
from an internal station or external call coming from a trunk. Internal calls generate one
ring, while external calls generate two rings with a very short pause between the rings.
No configuration is required.
When DND is turned on, either no audible rings occur during the ringing-in state of a
call, or no audible or visual notifications of any type occur.
Allows a user to enter a Fast Dial code to place a call. Fast Dial codes can be assigned
to phone numbers or Personal Address Book entries. See "Services" in this table.
Allows an administrator to set the sidetone level of a wired headset.
Limits the amount of time that a call can be on hold before reverting back to the phone
that put the call on hold and alerting the user.
Reverting calls are distinguished from incoming calls by a single ring (or beep, depending
on the new call indicator setting for the line). This notification repeats at intervals if not
resumed.
A call that triggers Hold Reversion also displays an animated icon in the call bubble.
You can configure call focus priority to favor incoming or reverting calls.
Enables phones with a shared line to distinguish between the local and remote lines that
placed a call on hold.
Allows the user to move a connected call from an active state to a held state.
• No configuration required unless you want to use Music On Hold. See "Music On
Hold" in this table for information.
• See "Hold Reversion" in this table.
