Cyclic ringing in Hunt Groups

Hi everybody,

I'm configuring hunt groups in a CCM 4.3 (2) and it works fine (I think so). The problem is that I'd like to make the call remains ringing in the same group, even though there's no answer, until someone in the hunt group could be available to attend it.

Now, the behaviour is that the call jumps from one phone to the next one in the group following the "Longest Idle Time" algorithm till the last phone, when the process stops and the call fails.

I'm a new admin and have no experience in this so I need your help.

Thanks in advance to everybody.

Re: Cyclic ringing in Hunt Groups

Hi Jose,

You have to be a little careful leaving a Caller for too long with these type of Hunt Groups. As there is no Queue Music or Queue Message being played the caller just hears "Ringback Tone" and if left too long this comes across as a "Ring No Answer" situation. You can play with the settings shown below to keep the call available for some time before being routed to Voicemail as a final step;

So you might need to use a Hunt Group with the "Circular Hunting" Algorithm and leverage this RNA setting;

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.

Under "Line Group Configuration", you can find (and change) the "RNA Reversion Timeout" (which is by default set to 10 seconds)

From this doc;

http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_administration_guide_chapter09186a00803edabe.html#wp107892

If the call goes unanswered then a Forward should be applied at the "Hunt Pilot" Level that routes the caller to a Voicemail box for the Group ;

Hunt Forward Settings

Forward Hunt No Answer - When the call that is distributed through the hunt list is not answered in a specific time, this field specifies how to forward the call.

Destination This setting indicates the directory number to which calls are forwarded. (This can be the Directory Number of the Unity VM Pilot)

Forward Hunt Busy - When the call that is distributed through the hunt list is busy in a specific time, this field specifies how to forward the call.

Destination This setting indicates the directory number to which calls are forwarded. (This can be the Directory Number of the Unity VM Pilot)

Maximum Hunt Timer - Enter a value (in seconds) that specifies the maximum time for hunting.(Used in conjunction with Forward Hunt Busy)

Hope this helps!

Rob
