At a glance

What this phone asks for, and how it finds it

Vendor
Snom
Family
Entry desk phone
Capacity
2 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

  1. Not individually confirmed for this entry model. The D7xx/D8xx rescue-mode reset (dial **## on the keypad, keep the last # pressed until Rescue Mode appears, then choose the settings-reset option) is documented for Snom's D-series generally; confirm it applies to the D120 specifically, or use the phone's own web interface, before relying on a keypad sequence.

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.

Not independently verified for this model

The factory reset procedure above is our best documented starting point, not a confirmed keystroke sequence for this exact model. Where it says to confirm something, do that before relying on it on a customer's desk.

Next

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.
