Hi Everyone,
I have Mitel 485G phones and we use RingCentral. A few months back, I was following this guide to set up my phones in RC. These steps are no longer working for me. After I set the configuration server, the phone reboots and hits me with a “no service” message.
Does anyone know of any other ways to add the phone to RC?
Thank you.

If your Mitel 485G shows "No Service," it usually means it hit the server but didn't finish the firmware migration. Try these basic steps:
Rebooting isn't enough; you must clear the old configuration:
While the phone is idle, press Mute.
Dial 25327# (CLEAR#).
Select Clear when prompted. The phone will reboot.
Press Mute, then dial 73887# (SETUP#).
Go to Services > Config Server.
Ensure the address is exactly: 34.110.141.137
Save and select Apply to reboot again.
Once the phone reboots, look for a message: "Dial 400 to switch to RC".
Lift the handset, dial 400, and press Dial.
The screen should say "Upgrading". This can take 15 minutes and involve multiple reboots. Do not unplug it.
If the steps above fail, your phone may require a manual firmware bridge or have a hardware revision conflict.
Please submit a support ticket via the RingCentral Support Portal to speak with our Dedicated Deskphone Support team. They can verify your device's MAC address and guide you through the specific conversion process for your hardware.

Hi Mary,
Thanks for the response. I have followed your steps to a tee, but unfortunately still receive the same “no service” message. I’ve tried using numerous different ethernet cables - even ones that currently have working phones.
What else can I try?
Thanks,

Hi Mary,
I reached out to RingCentral support, but we were not able to resolve my issue. The web interface on this phone does not work until the phone is fully configured. It’s looking like I’m going to have to order new phones - steering clear from Mitel this time.
