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.
