Cisco CME 4331 license for 3rd party guardian IP phones

[adeebtaqui]

Hi, I want to know if Cisco CME 4331V with CME licenses can support for 64 outdoor Guardian IP phones. Is there any other license necessary?

Hi,

As per below compatibility matrix, Cisco 4331 supports 100 SIP Phones with recommended DRAM and Flash Memory:

Other than CME licenses, you don't need any other licenses. But I would recommend you to test third party SIP Phones thoroughly with CME and see if it meets all your requirements.
