Provisioning a Snom 300, 320, 360, 370 IP Phone for 3CX

This guide shows you how to automatically provision the Snom 3 series of IP phones which includes the Snom 300, 320, 360, 370 phones for use with 3CX Phone System for Windows using the plug and play feature. This guide has been tested with the latest firmware versions supported by 3CX Phone System 14.0 and 12.5. Some phone models may only be available in the latest versions of the 3CX Phone System.

The easiest way to set up a snom 3 series IP phone for use with 3CX Phone System is to use the built-in plug and play provisioning functionality that’s provided for you inside the 3CX Management Console. By auto provisioning your Snom 300, 320, 360 and 370, your phone configures itself by retrieving a 3CX-generated phone configuration file.

Step 1: Verify Firmware Installed on Your Snom 300, 320, 360, 370 IP Phone


You’ll need to verify that the firmware version that’s currently installed on your Snom phone is the 8.7.3.25 firmware version as older firmwares might not have the plug and play feature equipped. To check which firmware is installed on your Snom 300, 320, 360, 370 phone, power up the phone and click on Menu > Information > Status Info. 3CX Phone System 12 users that have 3CX Maintenance Agreement can update their Snom firmware directly in 3CX Phone System 14.0 & 12.5 by logging into the 3CX Management Console once the phone is provisioned. To do this, visit the Phones node and select your Snom 300, 320, 360, 370 and click on the Upgrade Firmware button.

Step 2A: Provisioning a Snom 300, 320, 360, 370 Phone Using Plug and Play


To begin Plug and Play provisioning plug your Snom 300, 320, 360, 370 IP phone into the same LAN subnet as the PBX and power it up. Make sure you’ve plugged your phone into the same LAN subnet as the machine that has 3CX installed on it (3CX Phone System must run on port 5060). If you are trying to provision an extension in a remote network (WAN) in a different subnet, or on a PBX whose default port is not 5060 please skip this step and see Step 2B.
Snom-PnP
Now you need to approve the snom’s registration and assign an extension to it. It’s really easy to do. Simply follow the below steps:

  1. Click on the Phones node within the 3CX Management Console.
  2. When you’ve plugged in your snom phone, you’ll see it appear at the top of the list in bold.
  3. By right clicking on your Snom 300, 320, 360, 370, you’re given the option to select the following:
    • Add Extension – this will create a new extension.
    • Assign to Existing Extension – this will assign an existing extension.
  4. Now assign or create an extension and click OK.
  5. You will be taken to the Edit Extension settings page.
  6. To configure BLF function keys or speed dials in the ‘Phone Provisioning’ tab see the Optional Step at the end of this guide.
  7. Click OK.

3CX Phone System will send a provisioning link to your snom phone. Once your Snom 300, 320, 360, 370 phone receives the link, it will apply the configuration on the fly, and your phone will be ready to use. If a firmware update is needed, a restart will be performed.

Step 2B: Provisioning a Snom 300, 320, 360, 370 IP Phone Using a Provisioning Link


This method can be used to provision a snom IP Phone which does not reside in the same LAN subnet as the 3CX Phone System (including Lan2Lan VPN), on a system which the 3CX Phone System Service is not running on SIP Port 5060 or the IP phone is a remote extension connected via WAN to the 3CX Phone System. This process can also be automated if your network features a DHCP Server with Option 66. If you are attempting to provision a remote extension you should also be familiar with the concepts and information in the Remote Extension Provisioning Guide. To provision an extension please follow the next steps:

  1. Log in to your 3CX Management Console.
  2. Go to the extensions node and create or select the extension that you want to assign to your Snom 300, 320, 360, 370 IP Phone.ProvStunServerMode2
  3. Click on the Phone provisioning tab and fill in your phone’s MAC Address. You can find the Mac Address of your Snom 300, 320, 360, 370 by turning the phone over and looking at the MAC sticker on the back. Select a Model from the drop down list (according to which one you are configuring).
  4. Select your display language, and make sure that the ‘Select Provisioning Method’ is set to ‘Remote Extension (STUN)’ if you are provisioning an extension in a remote network or if you are provisioning an extension in another subnet select ‘Local Lan’.
  5. If you want to change your Codec Priority or configure BLFs please see the Optional Step at the end of this Guide. Press OK when you have selected your desired settings to save them.ProvURL4
  6. Click on the Settings tab and select the Phone Provisioning tab. Write down the External Provisioning URL (or the Internal one if you are provisioning an extension in a local subnet) as that will be used in the next step.

This procedure will create a provisioning file for your Snom 300, 320, 360, 370 IP Phone. The next step will be to instruct the phone to retrieve that file.

Getting your Remote snom IP Phone to Register with 3CX

  1. Start up your snom IP phone and identify its IP address. To find your phone’s IP address, simply press the OK key on the phone. In this example we’re going to assume that the IP address of your Snom phone is 10.172.0.197 and the External IP address of the server (or PC) where 3CX Phone System is installed is mybusiness.contoso.com
  2. Point your browser to the web interface of your snom series phone, which in this example is http://10.172.0.197.
  3. You will be logged into your snom’s web interface.
    SnomProvURL
  4. Select the Advanced section from the left menu of the snom web interface and then click on the Update tab. Paste the link that you copied in step 6 of Part 2B into the ‘Server URL’ field as shown above and add /cfg{mac} at the end of the provisioning link (note that in the above image only part of the Provisioning URL is shown due to the field length).
  5. Press Apply and then the Reboot button to have your Snom 300, 320, 360, 370 IP Phone retrieve the provisioning file from 3CX Phone System and apply it. Your snom phone will reboot and once it restarts your phone will be provisioned and connected to 3CX Phone System.

Optional Step- Configure BLF Function Keys on Your Snom 300, 320, 360, 370 IP Phone


Your snom phone has function keys that can be provisioned. This can be done in the 3CX Management Console from the BLF (Busy Lamp Field) tab in the extension settings. On Snom phones the blf keys are shifted by 2 making the first two entries on the phone always “Line” keys.
BLF-Keys

  1. In the Edit Extension page, navigate to the BLF (Busy Lamp Field) tab
  2. Configure the function keys for BLF, Shared Parking and other various types of Speed Dials.
  3. Click OK.

Once you’ve clicked OK, your snom IP phone will provision itself automatically and may reboot. Congratulations! You have configured your Snom 300, 320, 360, 370 phone using 3CX.
