Telephony Features Available for the Cisco Unified IP Phone

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

Auto-pickup

Allows a user to use one-touch pickup

functionality for call pickup features.

For more information, see the

Cisco Unified

Communications Manager Features and

Services Guide

Call Pickup

Block external to

external transfer

Prevents users from transferring an external call to

another external number.

For more information, see the

Cisco Unified

Communications Manager Features and

Services Guide

External Call Transfer

Restrictions

Busy Lamp Field

(BLF)

Allows a user to monitor the call state of a

directory number associated with a speed-dial

button on the phone.

Services Guide
