VoIP desk phone showing 'No Service' on the screen
A VoIP phone needs an active network connection to work. Check that the phone is plugged in with a network cable or connected to WiFi, then restart it. If it's on WiFi, switch it to a network cable. That fixes most 'No Service' errors immediately.
VoIP phones work over your internet connection, not a traditional phone line. When the phone shows 'No Service', it means it can't reach the internet or your VoIP provider. The fastest fixes are checking the network cable connection, restarting the phone, and making sure it's not on WiFi when it should be on a cable.
- ✓Have access to the phone or audio system that needs troubleshooting
- ✓Have admin credentials ready if needed for system access
- ✓Have a test procedure ready to verify the fix (e.g., test call, test connection)

Skip, I just want a technicianCommon mistakes to avoid
- Leaving the phone on WiFi and wondering why it drops calls. Switch to a network cable and the problem disappears
- Assuming the internet is down without checking a computer first. Test another device before troubleshooting the phone
- Not waiting long enough for the phone to restart. VoIP phones take 60 seconds to fully reconnect after a restart
