Hi Yousif,

Just to add a note to Brandons great info. CME Licensing is Platform Specific. Have a look at the following;

Maximum Total IP Phones (Platform Specific)

Cisco 2801

24 IP Phones

Cisco 2811

36 IP Phones

Cisco 2821

48 IP Phones

Cisco 2851

96 IP Phones

Cisco 3825

168 IP Phones

Cisco 3845

240 IP Phones

From this good doc;

Hope this helps!


Edit: Brandon, please keep in mind that I flunked Typing 10 (I can't keep up :)

You cannot currently register more than 24 phones to a 2801.

You can register 30. This is because the real limits are a little higher than the official ones.

Good point. However, I think you'll only get support for 24.
