CUCM Invalid License Due to Change License MAC Parameters

[mario_aiad2014]

After we have modified NTP and set timezone on cisco call manager. We have faced the below message:
Licensing Warnings:
System is operating on Invalid licenses. Call Manager service will go down after the grace period of 30 days expires. Please obtain valid license files and upload.

Appreciate your help.

Open a Licensing TAC ticket. They will assist you on rehosting the license. Use below link to Open the case with TAC.

we didnt have support account as in the first this device was managed by another company and after be 2 companies we use but the problem happened when we changed NTP configuration. so, if there is any email can sent and contact with or any other way can use?

Your version must be 8.x or below, which are all EOS/EOL, as a best effort, you can try licensing TAC or your SE. No one else can help, they need to generate a new license to match the licensing MAC from your server, otherwise, set the NTP/timezone to what it was to go back to the previous licensing MAC.

No contract required, Just create an account on cisco portal.Login with your ID. Use the URL which shared  to open the case. 

They might request you the OLD MAC address,Or SO# Number or PAK details to rehost  the license.
