• Unified CM line groups offer four distribution algorithms: Top Down, Circular, Longest Idle Time and Broadcast. in context
• Cisco recommends no more than 35 directory numbers in a single line group that uses the Broadcast algorithm with call queuing. in context
• With the Circular algorithm, if a call to a logged-off agent is rejected with a reject type other than Huntlogout, the circular index does not increment and the next call goes to the same agent. in context
• A single Unified CM cluster supports a maximum of 15000 hunt list devices. in context
• The Release 15 hunt pilot configuration task flow is line groups first, then hunt lists, then hunt pilots. in context
• Cisco gives 1500 hunt lists of ten IP phones each or 750 hunt lists of twenty IP phones each as example combinations within the 15000 hunt list device limit. in context
• Cisco recommends setting the dial plan initialization timer service parameter to 600 seconds when 1500 hunt lists are configured. in context
• A Unified CM hunt list is a prioritized list of line groups. in context
• Unified CM line groups let multiple phones answer calls directed to a single directory number. in context
• The Release 15 System Configuration Guide states the maximum wait time in queue for a hunt pilot ranges from 0 to 3600 seconds with a default of 900. disputed in context
• Cisco does not recommend configuring Unified Mobility devices in a hunt pilot. in context
• When a call to a hunt pilot goes unanswered in the first line group of the hunt list, Unified CM offers the call to the next line group in the hunt list. in context
• Unified CM line groups cannot point to CTI ports or CTI route points so hunt pilots cannot distribute calls to CTI-controlled endpoints. in context
• A call distributed by a Unified CM hunt pilot overrides all partition and calling search space restrictions when it is offered to line group members. in context
• In Unified CM Release 15 a hunt pilot is a number or pattern plus associated digit manipulations that routes calls to a group of phones or directory numbers in a line group. in context
• The total number of queue slots across all queuing-enabled hunt pilots on one Unified CM node is limited to 3200. in context
• A single Unified CM subscriber node supports at most 100 hunt pilots with call queuing enabled. in context
• If Logged Into Hunt Group is unchecked on any device in the hunt group, a hunt call does not extend to that user's Single Number Reach remote destinations unless all devices are logged in. in context
• The Unified CM Hunt List Configuration window has a checkbox to mark the hunt list as used for voice mail. in context
