CME SIP 503 service unavailable phones not registering

Hello,

 

 I have an ISR4431 as a CME.

It has been working for a lot of time, but this morning all phones are not registering. The CME is binding IPs to the phones, and the phones are getting the *.cnf file from the CME, but when the phone is traying to register, the CME returns "Status: 503 Service Unavailable".

 

I put here some parts of the configuration.

I just realize this about licensing

This CME is in a network isolated from the internet. But it has benn working since a lot of time till yesterday...

 

It is possible to disable this smart license feature?

Whats your router model, and what's your iOS version. to disable smart licensing you need to downgrade. 

 

You can install On prem SSM if you dont want your cisco router to connect with internet.
