Line Group Configuration Settings

Table 24-1 describes the line group configuration settings.

Table 24-1 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 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 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 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 CallManager most recently extended a call. If the nth member is the last member of a line group, Cisco CallManager distributes a call starting from the top of the line group. •Longest Idle Time—If you choose this distribution algorithm, Cisco 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 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.
Hunt Options
No Answer	For a given distribution algorithm, choose a hunt option for Cisco 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 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 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 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 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 CallManager skips the remaining members of this line group when the RNA reversion timeout value elapses for the first member. Cisco CallManager then proceeds directly to the next line group in a hunt list. •Stop hunting—If you choose this hunt option, Cisco 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 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 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 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 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 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 CallManager skips the remaining members of this line group upon encountering a busy member. Cisco CallManager proceeds directly to the next line group in a hunt list. •Stop hunting—If you choose this hunt option, Cisco 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 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 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 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 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 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 CallManager skips the remaining members of this line group upon encountering the first unavailable member. Cisco CallManager proceeds directly to the next line group in a hunt list. •Stop hunting—If you choose this hunt option, Cisco CallManager stops hunting after trying to distribute a call to the first unavailable member of this line group.
Line Group Member Information
Find Directory Numbers to add to Line Group
Route Partition	Choose a route partition for this line group from the drop-down list box. If you click Find, the Available DN/Route Partition list box displays all DNs that belong to the chosen partition.
Directory Number Contains	Enter the character(s) that are found in the directory number that you are seeking and click the Find button. Directory numbers that match the character(s) that you entered display in the Available DN/Route Partition box.
Available DN/Route Partition	Choose a directory number in the Available DN/Route Partition list box and add it to the Selected DN/Route Partition list box by clicking Add to Line Group.
Current Line Group Members
Selected DN/Route Partition	To change the priority of a directory number, choose a directory number in the Selected DN/Route Partition list box. Move the directory number up or down in the list by clicking the arrows on the right side of the list box. To reverse the priority order of the directory numbers in the Selected DN/Route Partition list box, click Reverse Order of Selected DNs. For more information about the order of directory numbers in a line group, see "Route Plan Overview" in the Cisco CallManager System Guide. Note Do not put DNs that are shared lines in a line group that uses the Broadcast distribution algorithm. Cisco CallManager cannot display all DNs that are shared lines on devices where the DNs are configured as shared lines if the DNs are members of a line group that uses the Broadcast distribution algorithm.
Removed DN/Route Partition (to be removed from Line Group when you click Update)	Choose a directory number in the Selected DN/Route Partition list box and add it to the Removed DN/Route Partition list box by clicking the down arrow between the two list boxes.
