Description and More Information
Enables an IP Phone to sleep (power down) and wake (power up) at predetermined times,
to promote energy savings.
Improves the Secure Extension Mobility Cross Cluster (EMCC) feature by preserving
the network and security configurations on the login phone. By so doing, security policies
are maintained, network bandwidth is preserved and network failure is avoided within
the visiting cluster (VC).
With Feature Safe, your phone can use any phone button template that has the same
number of line buttons that the phone model supports.
Size Safe allows your phone to use any phone button template that is configured on the
system.
Controls the types of calls that certain users can place.
Allows an administrator to set the sidetone level of a wired headset.
Allows a user to answer a call that is ringing on a directory number in another group.
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 configurations are required unless you want to use Music On Hold. See "Music
On Hold" in this table.
• See "Hold Reversion" in this table.
Enhances the file download process to the phone to use HTTP by default. If the HTTP
download fails, the phone reverts to using the TFTP download.
Increases security by requiring communication using HTTPS.
Note When the web is in HTTPS mode, the phone is an HTTPS server.
Improves the display of caller names and numbers. If the Caller Name is known, then
the Caller Number is displayed instead of Unknown.
Provides support for expanded IP addressing on Cisco IP Phones. IPv6 support is provided
in standalone or in dual-stack configurations. In dual-stack mode, the phone is able to
communicate using IPv4 and IPv6 simultaneously, independent of the content.
The Jitter Buffer feature handles jitter from 10 milliseconds (ms) to 1000 ms for both
audio and video streams.
Allows users to combine calls that are on multiple phone lines to create a conference call.
Some JTAPI/TAPI applications are not compatible with the Join and Direct Transfer
feature implementation on the Cisco IP Phone and you may need to configure the Join
and Direct Transfer Policy to disable join and direct transfer on the same line or possibly
across lines.
