FreePBX Trunk Down

Hi we currently are currently using FreePBX version 15.0.23.11 and Asterisk Version: 16.24.0 at our company with ± 200 users we are currently facing an issue were the FreePBX has a trunk down everyday at 15:30 when are users shutdown there computers we believe it to be the switches.

Or can it be one of are settings because we are currently moving to a newer version of asterisk and FreePBX but we don’t want the same issues when we convert to the newer versions.

The users are also in different ring groups at the moment.
