Line Group Configuration


A line group allows you to designate the order in which directory numbers are chosen. Cisco Unified CallManager distributes a call to idle or available members of a line group based on a call distribution algorithm and on the Ring No Answer Reversion (RNAR) Timeout setting.

Use the following topics to add or delete a line group or to add directory numbers to or to remove directory numbers from a line group:

Finding a Line Group

Because you may have several line groups in your network, Cisco Unified CallManager lets you locate specific line groups based on specific criteria. Use the following procedure to locate line groups.


Note During your work in a browser session, Cisco Unified CallManager Administration retains your line group search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified CallManager Administration retains your line group search preferences until you modify your search or close the browser.


Procedure


Step 1 Choose Call Routing > Route/Hunt > Line Group.

The Find and List Line Groups window displays.

Step 2 From the drop-down list box, choose one of the following criteria:

begins with

contains

is exactly

ends with

is empty

is not empty

Step 3 Specify the appropriate search text, if applicable, and click Find. You can also specify how many items per page to display.


Note To find all line groups registered in the database, click Find without entering any search text.


A list of discovered line groups displays by line group name.


Tip To search for line groups within the search results, click the Search Within Results check box and enter your search criteria as described in this step.



Note You can delete multiple line groups from the Find and List Line Groups window by checking the check boxes next to the appropriate line groups and clicking Delete Selected. You can delete all of the line groups in the window by clicking Select All and clicking Delete Selected.


Step 4 From the list of records, click the line group that matches your search criteria.

Configuring a Line Group

The following procedure describes how to configure a line group.

Before You Begin

You must define one or more directory numbers before performing this procedure.

Procedure


Step 1 Choose Call Routing > Route/Hunt > Line Group.

Step 2 Perform one of the following tasks:

To copy an existing line group, locate the appropriate line group as described in the "Finding a Line Group" section, click the Copy button next to the line group that you want to copy, and continue with Step 3.

To add a new line group, click the Add New button, and continue with Step 3.

To update an existing line group, locate the appropriate line group as described in the "Finding a Line Group" section, and continue with Step 3.

Step 3 In the Line Group Configuration window that displays, enter a name in the Line Group Name field. The name can contain up to 50 alphanumeric characters and can contain any combination of spaces, periods (.), hyphens (-), and underscore characters (_). Ensure that each line group name is unique to the route plan.


Timesaver Use concise and descriptive names for your line groups. The CompanynameLocationGroup format usually provides a sufficient level of detail and is short enough to enable you to quickly and easily identify a line group. For example, CiscoDallasAA1 identifies a Cisco Access Analog line group for the Cisco office in Dallas.


Step 4 Choose the appropriate settings as described in Table 35-1.

Step 5 To add or update this line group, click Save.

Line Group Configuration Settings

Table 35-1 describes the line group configuration settings.

Table 35-1 Line Group Configuration Settings 

Field
Description
Line Group Information

Line Group Name

Enter a name for this line group. The name can comprise up to 50 alphanumeric characters and can contain any combination of spaces, periods (.), hyphens (-), and underscore characters (_). Ensure that each line group name is unique to the route plan.

RNA Reversion Timeout

Enter a time, in seconds, after which Cisco Unified CallManager will distribute a call to the next available or idle member of this line group or to the next line group if the call is not answered and if the first hunt option, Try next member; then, try next group in Hunt List, is chosen. The RNA Reversion Timeout applies at the line-group level to all members.

Distribution Algorithm

Choose a distribution algorithm, which applies at the line-group level, from the options in the drop-down list box:

Top Down—If you choose this distribution algorithm, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member.

Circular—If you choose this distribution algorithm, Cisco Unified CallManager distributes a call to idle or available members starting from the (n+1)th member of a line group, where the nth member is the member to which Cisco Unified CallManager most recently extended a call. If the nth member is the last member of a line group, Cisco Unified CallManager distributes a call starting from the top of the line group.

Longest Idle Time—If you choose this distribution algorithm, Cisco Unified CallManager only distributes a call to idle members, starting from the longest idle member to the least idle member of a line group.

Broadcast—If you choose this distribution algorithm, Cisco Unified CallManager distributes a call to all idle or available members of a line group simultaneously. See the Note in the description of the Selected DN/Route Partition field for additional limitations in using the Broadcast distribution algorithm.

The default value specifies Longest Idle Time.

Hunt Options

No Answer

For a given distribution algorithm, choose a hunt option for Cisco Unified CallManager to use if a call is distributed to a member of a line group that does not answer. This option gets applied at the member level. Choose from the options in the drop-down list box:

Try next member; then, try next group in Hunt List—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. If unsuccessful, Cisco Unified CallManager then tries the next line group in a hunt list.

Try next member, but do not go to next group—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. Cisco Unified CallManager stops trying upon reaching the last member of the current line group.

Skip remaining members, and go directly to next group—If you choose this hunt option, Cisco Unified CallManager skips the remaining members of this line group when the RNA reversion timeout value elapses for the first member. Cisco Unified CallManager then proceeds directly to the next line group in a hunt list.

Stop hunting—If you choose this hunt option, Cisco Unified CallManager stops hunting after trying to distribute a call to the first member of this line group and the member does not answer the call.

Busy

For a given distribution algorithm, choose a hunt option for Cisco Unified CallManager to use if a call is distributed to a member of a line group that is busy. Choose from the options in the drop-down list box:

Try next member; then, try next group in Hunt List—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. If unsuccessful, Cisco Unified CallManager then tries the next line group in a hunt list.

Try next member, but do not go to next group—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. Cisco Unified CallManager stops trying upon reaching the last member of the current line group.

Skip remaining members, and go directly to next group—If you choose this hunt option, Cisco Unified CallManager skips the remaining members of this line group upon encountering a busy member. Cisco Unified CallManager proceeds directly to the next line group in a hunt list.

Stop hunting—If you choose this hunt option, Cisco Unified CallManager stops hunting after trying to distribute a call to the first busy member of this line group.

Not Available

For a given distribution algorithm, choose a hunt option for Cisco Unified CallManager to use if a call is distributed to a member of a line group that is not available. The Not Available condition occurs when none of the phones that are associated with the DN in question are registered. Not Available also occurs when Extension Mobility is in use and the DN/user is not logged in. Choose from the options in the drop-down list box:

Try next member; then, try next group in Hunt List—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. If unsuccessful, Cisco Unified CallManager then tries the next line group in a hunt list.

Try next member, but do not go to next group—If you choose this hunt option, Cisco Unified CallManager distributes a call to idle or available members starting from the first idle or available member of a line group to the last idle or available member. Cisco Unified CallManager stops trying upon reaching the last member of the current line group.

Skip remaining members, and go directly to next group—If you choose this hunt option, Cisco Unified CallManager skips the remaining members of this line group upon encountering the first unavailable member. Cisco Unified CallManager proceeds directly to the next line group in a hunt list.

Stop hunting—If you choose this hunt option, Cisco Unified CallManager stops hunting after trying to distribute a call to the first unavailable member of this line group.
