Issue with phones dropping

[jkhattar]

Been having an issue lately with our system where phones will suddenly lose connection at seemingly random spots throughout the day.
The phones will go out for a seconds, then reconnect right after. This doesn't affect anyone currently on a call either
We've tried updating, checking network connections, changing out phones, restarting the server, but nothing seems to do the trick.
Tried checking for errors in the logs, but not coming across any

This is something you might need to raise with the phone manufacturer's support.
