Step 1: Upgrade to Minimum required firmware
Check that the phone is running the minimum firmware described above. Read how to check what firmware the phones are running and how to upgrade them in this guide: How to manual upgrade snom ip phones.
Step 2: Factory Reset the IP Phone
Before provisioning the IP phone, the phone must be brought back to factory defaults in case the device has residual settings of a previous configuration. To reset the device read our How to factory reset snom 3 series phones or How to factory reset snom D3 series phones documents.
Step 3: Provision the phone
There are several methods to provision a phone:
- Plug & Play - For phones on the local LAN or behind the 3CX SBC.
- RPS - For phones on remote networks that will connect directly to 3CX and use STUN
For more information, see “When can I use which provisioning method?”.
Local LAN or SBC: Provision via Plug’n’Play
- Connect the phone to the network. A PnP request will be sent automatically to 3CX.
- Go to the 3CX Management Console ⇒ “Phones” page. The new phone will be marked in Bold.
- Click on the BOLD entry and choose between “Assign Ext” or “Add Ext”, depending on whether you want to assign the phone to an existing extension or create a new one.
- All major provisioning settings are pre-populated. If your PBX has multiple network cards, select to which network this IP Phone is connected.
- Click “OK”. The phone will configure automatically and will reboot to finalize the setup.
Remote phones: Provision via RPS server
- Take note of the phone’s MAC address, usually written at the back.
- Navigate to the 3CX Management Console ⇒ “Phones” and press “+ Add Phone”.
- From the dropdown list select the extension to which this phone must be assigned.
- In the next dialog select the Vendor/Model of the phone and enter the device’s MAC address.
- Switch the “Provisioning Method” to “Direct SIP (Stun - Remote)” and click “OK”.
- You can make sure that the extension is ready to be configured via RPS by checking the “Event Log” from the dashboard:
If the message appears as a “Warning” follow the instructions outlined in the message and use the Manual Link Provisioning method outlined here.
- The phone is now ready to be provisioned - you can boot up the phone anywhere in the world with access to the internet.
- The phone will prompt for username and a password: Enter the the extension number as username and the voicemail pin as the password.
Note: Ensure that the input mode is set to digits (green box).
Important note about BLF Layout
On all snom devices the BLF keys are mapped to allocate the first two keys as line keys. As a result, the first assigned BLF key from 3CX will be located on the 3rd available button on the device.
Button assignment exceptions apply for:
- snom 300 (Line, Line, Redial, Address Book, Transfer, Hold)
- snom D305 and snom D315 (Line, Line, Redial, Address Book, Transfer)
Leave the device with NO free configurable BLF buttons unless the extension (sidecar) module is been used.
- snom 3 series is EOL.
- Final firmware for snom 3 series: 126.96.36.199 (snom 360 188.8.131.52.9).
- snom 360 can only be used within the local LAN.
