Solved Outgoing international calls fail with "Forbidden" outside of business hours

[jst2]

I am facing a very odd problem. On a weekday, I can make international calls just fine, but it stopped working during weekends for the past 2-3 weeks. All phones show "Forbidden". Am I missing some configuration somewhere? I am just confused by this odd behavior. Any help is appreciated.

Hi @jst2

Have you spoken to your provider? Perhaps they implemented some safe guards for the weekends?

Hi Yiannis,

Thank you for pointing me in the right direction. My provider had implemented some new security features and I had missed some notifications on when they will be turned on. In my case, it was related to "Outbound Call Authorization". After making a few changes on the provider configuration web page everything went back to normal.

Glad to see you were able to resolve the issue.
