Shared line vs Hunt Group

[Syed]

Dear All,

I have service desk with 10 members and I am using shared line and all is working fine. But I would like to go for hunt group because I can choose call algorithm accordingly. So, may I know the advantages & disadvantages or comparison between these two?

Thank you in advance.

Hi Syed,

you have two option available with Hunt group, Traditional hunting and Queuing. both have there own advantages see below for details.

Also shared line would not give you different hunting algorithms that Hunt configuration will do.

Hello JB,

Thank you for your quick response.

I am on cucm version 8.5.1, and as per the document I think queuing does not working.

Hi Syed,

you are right queuing was introduced from version 9.X but the hunt options are available with traditional hunting.

Shared line has ringing limit as a normal call (meaning all phones that share a DN will ring as per default ringing duration) but does it keep ringing until some answer call in the gruop in case of hunt group, am I correct?

It will ring depending on distribution algorithm selected

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 CM 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 CM distributes a call to idle or available members starting from the (n+1)th member of a route group, where the nth member is the next sequential member in the list who is either idle or busy but not "down." If the nth member is the last member of a route group, Cisco Unified CM distributes a call starting from the top of the route group. Longest Idle Time—If you choose this distribution algorithm, Cisco Unified CM 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 CM 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.

in case of No answer it would do below.

No Answer

For a given distribution algorithm, choose a hunt option for Cisco Unified CM 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 CM 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 CM 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 CM 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 CM 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 CM skips the remaining members of this line group when the RNA reversion timeout value elapses for the first member. Cisco Unified CM then proceeds directly to the next line group in a hunt list. Stop hunting—If you choose this hunt option, Cisco Unified CM stops hunting after trying to distribute a call to the first member of this line group and the member does not answer the call.
