CME - max phone limit 72 or 96 ?

[thisisshanky]

The documentation is clearly misleading.

One document says, 2851 can support upto 72 phones on CME, while another says 96. Which one is the right info ?

http://www.cisco.com/en/US/products/ps5882/index.html --- shows as 72.

http://www.cisco.com/en/US/products/sw/voicesw/ps4625/prod_release_note09186a008055677f.html ----- shows as 96.

[r.humphries · Accepted solution]

"This solution is for customers with data-connectivity requirements interested in deploying a converged IP telephony solution for up to 72 IP phones and-as of Cisco IOS 12.3(11) release-for up to 96 IP phones."

Michael,

Seems like, the software programmer mixed up 72 and 96 to 76 ? LOL.

[michael_davis]

Yeah, I guess they should've asked the forum before coding... LOL
