At a glance
What this phone asks for, and how it finds it
- Vendor
- Snom
- Family
- Colour desk phone
- Capacity
- Multiple SIP accounts
- Provisioning file
- <mac>.xml
- Other files it requests
- directory.xml (the pushed company directory)
- DHCP option
- Option 66 and 67
- MAC address
- Printed on a label on the underside of the phone, and on the outer box.
Option 66 carries the server address and option 67 carries the filename; the phone stores them as its own update_server and update_filename settings. A Snom phone tries its own cloud redirection service before either of these, so the platform writes its provisioning address into the delivered configuration file as well, not only into DHCP.
Factory reset
Returning this phone to defaults
Steps
- On the phone's keypad: dial **## to reboot the phone, and keep the final # key held down. The phone boots into Rescue Mode. Choose the settings-reset option, then confirm the reboot.
- A settings reset keeps the phone's firmware and its certificates; it does not touch either.

If it does not come up
- Confirm the phone has a network cable connected.
- Confirm the model recorded for this device matches the label on the phone exactly.
- Confirm a line is assigned to the device in the portal.
- If the phone previously worked elsewhere, factory reset it before enrolling. A Snom phone that already has a setting_server saved will still try that address first.

Set the matching DHCP option once on your own network, and every Snom phone you plug in after this one finds the platform on its own.
