[cisco-voip] hunt pilot number limitation

[James Buchanan]

The only guidelines in Cisco’s SRND (www.cisco.com/go/srnd) I could find are copied below:

 

 

Hunt Pilot Scalability 

Cisco recommends using the following guidelines when deploying call coverage using top-down, circular, and longest-idle algorithms: • The Unified CM cluster supports a maximum of 15,000 hunt list devices. • The hunt list devices may be a combination of 1500 hunt lists with 10 IP phones in each hunt list, or a combination of 750 hunt lists with 20 IP phones in each hunt list. However, an increase in a number of hunt lists can require increasing the dial plan initialization timer specified in the Unified CM service parameters. Cisco recommends setting the dial plan initialization timer to 600 seconds if 1500 hunt lists are configured.

Note that a BHCA of 10 on a hunt pilot pointing to a hunt list or hunt group containing 10 phones and using the broadcast algorithm is equivalent to 10 phones with a BHCA of 10. • Cisco recommends having a maximum of 35 directory numbers in a single line group configured to send the calls simultaneously to all DNs. Additionally, the number of broadcast line groups depends on the BHCC. If there are multiple broadcast line groups in a Unified CM system, the number of maximum directory numbers in a line group must be less than 35. The number of busy hour call attempts (BHCA) for all the broadcast line groups should not exceed 35 calls set up per second.

Hi all,

Anybody knows what is the limitation of hunt pilot numbers on CUCM 6.x.x ? We use 6.1.2 and need the exact number.

Any help will be appreciated..
