    We are having an issue on 3cx V.15 where phones are dropping out several times a day and disrupting staff and calls. We are using Snom 715s. I believe I have tracked the issue down in the logs. I have pasted it in below.

    I'm not sure why it looks like the phones need to reauthenticate with the server all the time. Is there a way to resolve this problem?
