Telephony Features Available for the Cisco Unified IP Phone
Assisted Directed Call
Park (SIP only)
Enables users to park a call by pressing only one
button using the Direct Park feature.
Administrators must configure a Busy Lamp Field
(BLF) Assisted Directed Call Park button. When
users press an idle BLF Assisted Directed Call
Park button for an active call, the active call is
parked at the Direct Park slot associated with the
Assisted Directed Call Park button.
For more information, see the Cisco Unified
Communications Manager Features and
Services Guide, Assisted Directed Call Park.
Audible Message
Waiting Indicator
(AMWI)
A stutter tone from the handset, headset, or
speakerphone indicates that a user has one or more
new voice messages on a line.
Note The stutter tone is line-specific. You hear it
only when using the line with the waiting
messages.
For more information, see the Cisco Unified
Communications Manager System Guide,
Cisco Unified IP Phone.
Auto Answer Connects incoming calls automatically after a ring
or two.
Auto Answer works with either the speakerphone
or the headset.
For more information, see the Cisco Unified
Communications Manager Administration
Guide, Directory Number Configuration.
Automatic Port
Synchronization
When the Cisco Unified CM administrator uses the
Remote Port Configuration feature to set the speed
and duplex function of an IP phone remotely, loss
of packets can occur if one port is slower than the
other.
The Automatic Port Synchronization feature
synchronizes the ports to the lowest speed among
the two ports, which eliminates packet loss. When
automatic port synchronization is enabled, it is
recommended that both ports be configured for
autonegotiate. If one port is enabled for
autonegotiate and the other is at a fixed speed, the
phone synchronizes to the fixed port speed.
Note If both the ports are configured for fixed
speed, the Automatic Port Synchronization
feature is ineffective.
The Remote Port Configuration and
Automatic Port Synchronization features
are compatible only with IEEE 802.3AF
Power of Ethernet (PoE) switches.
Switches that support only Cisco Inline
Power are not compatible. Enabling this
feature on phones that are connected to
these types of switches could result in loss
of connectivity to Cisco Unified CM, if the
phone is powered by PoE.
To configure the parameter in the Cisco
Unified CM Administration application,
choose Device > Phone, select the appropriate
IP phones, and scroll to the Product Specific
Configuration Layout pane.
To configure the setting on multiple phones
simultaneously, enable Automatic Port
Synchronization in either the Enterprise Phone
Configuration (System > Enterprise Phone
Configuration) or the Common Phone Profile
Configuration (Device > Device Settings >
Common Phone Profile).
