Feature Information for Automatic Line Selection

Configuring Automatic Line Selection

Last Updated: January 2, 2008

 

This chapter describes automatic line selection features in Cisco Unified Communications Manager Express (Cisco Unified CME).

Finding Feature Information in This Module

Your Cisco Unified CME version may not support all of the features documented in this module. For a list of the versions in which each feature is supported, see the “Feature Information for Automatic Line Selection” section.

Information About Automatic Line Selection

To enable automatic line selection, you should understand the following concept:

Automatic Line Selection for Incoming and Outgoing Calls

On multiline IP phones, lifting the handset automatically selects the first ringing line on the phone or, if no line is ringing, selects the first available idle line for outgoing calls. This is the default behavior for all multiline IP phones.

Under some circumstances, however, you might want to require that a line button be explicitly pressed to select an outgoing line or to answer an incoming call. In Cisco CME 3.0 and later, you have the flexibility to assign the type of line selection that each IP phone uses.

The Automatic Line Selection feature allows you to specify, on a per-phone basis, the line that is selected when you pick up a phone handset.

Any of the following behaviors can be assigned on a per-phone basis:

  • Automatic line selection—Picking up the handset answers the first ringing line or, if no line is ringing, selects the first idle line. Use the auto-line command with no keyword or argument. This is the default.
  • Manual line selection (no automatic line selection)—Pressing the Answer soft key answers the first ringing line, and pressing a line button selects a line for an outgoing call. Picking up the handset does not answer calls or provide dial tone. Use the no auto-line command.
  • Automatic line selection for incoming calls only—Picking up the handset answers the first ringing line, but if no line is ringing, it does not select an idle line for an outgoing call. Pressing a line button selects a line for an outgoing call. Use the auto-line incoming command.
  • Automatic line selection for outgoing calls only—Picking up the handset for an outgoing call selects the line associated with the button-number argument. If a button number is specified and the line associated with that button is unavailable (because it is a shared line in use on another phone), no dial tone is heard when the handset is lifted. You must press an available line button to make an outgoing call. Incoming calls must be answered by pressing the Answer soft key or pressing a ringing line button. Use the auto-line command with the button-number argument.
  • Automatic line selection for incoming and outgoing calls—Pressing the Answer soft key or picking up the handset answers an incoming call on the line associated with the specified button. Picking up the handset for outgoing calls selects the line associated with the specified button. Use the auto-line command with the button-number argument and answer-incoming keyword.

How to Configure Automatic Line Selection

This section contains the following tasks:

SCCP: Enabling Automatic Line Selection

To enable automatic line selection for answering incoming calls or making outgoing calls, perform the following steps:

Restrictions

Automatic line selection is bypassed if it is configured for a trunk directory number and the line is seized by pressing the Park or Callfwd soft keys. The first available directory number is seized.

SUMMARY STEPS

1. enable

2. configure terminal

3. ephone phone-tag

4. auto-line [ button-number [ answer-incoming ] | incoming ]

5. end

DETAILED STEPS

Command or Action
Purpose

Step 1

enable

 

Router> enable

Enables privileged EXEC mode.

  • Enter your password if prompted.

Step 2

configure terminal

 

Router# configure terminal

Enters global configuration mode.

Step 3

ephone phone-tag

 

Router(config)# ephone 24

Enters ephone configuration mode.

  • phone-tag —Unique sequence number for the phone on which you want to configure automatic line selection.

Step 4

auto-line [ button-number [ answer-incoming ] | incoming ]

 

Router(config-ephone)# auto-line 5 answer-incoming

Assigns a type of line selection behavior to this phone.

  • auto-line —Picking up the handset answers the first ringing line or, if no line is ringing, selects the first idle line. This is the default.
  • auto-line button-number —Picking up the handset for an outgoing call selects the line associated with the specified button. The default if this argument is not used is the topmost available line.
  • auto-line button-number answer-incoming —Picking up the handset answers the incoming call on the line associated with the specified button.
  • auto-line incoming —Picking up the handset answers the first ringing line but, if no line is ringing, does not select an idle line for an outgoing call. Pressing a line button selects a line for an outgoing call.
  • no auto-line —Disables automatic line selection. Pressing the Answer soft key answers the first ringing line, and pressing a line button selects a line for an outgoing call. Picking up the handset does not answer calls or provide dial tone.

Step 5

end

 

Router(config-ephone)# end

Returns to privileged EXEC mode.

Verifying Automatic Line Selection


Step 1 Use the show running-config command to verify your configuration. Automatic line selection is listed in the ephone portion of the output.

Router# show running-config

ephone 2

headset auto-answer line 1

headset auto-answer line 4

ephone-template 1

mac-address 011F.9010.1790

paging-dn 48

type 7960

no dnd feature-ring

no auto-line

Step 2 Use the show telephony-service ephone command to display only ephone configuration information.

Router# show telephony-service ephone

ephone 4

device-security-mode none

username "Accounting"

mac-address FF0E.4857.5E91

button 1c34,35

no auto-line


 

Configuration Examples for Automatic Line Selection

This section contains the following example:

Automatic Line Selection: Example

The following example assigns no automatic line selection to phones 1 and 2 and assigns automatic line selection for incoming calls only to phone 3:

ephone 1

mac-address 00e0.8646.9242

button 1:1 2:4 3:16

no auto-line

!

ephone 2

mac-address 01c0.4612.7142

button 1:5 2:4 3:16

no auto-line

!

ephone 3

mac-address 10b8.8945.3251

button 1:6 2:4 3:16

auto-line incoming

The following example enables automatic selection of line button 1 when the handset is lifted to answer incoming calls or to make outgoing calls.

ephone 1

mac-address 0001.0002.0003

type 7960

auto-line 1 answer-incoming

button 1:1 2:2 3:3
