Article Summary


Note : For snom 300-series provisioning check if you have to open the extension for provisioning (see below, Pairing the phone with the Vodia PBX). If you want to reset a Snom 3xx series phone and provision it, please follow the link

Note : For snom m9 provisioning, a few extra steps are required.

Note : For snom M700 provisioning, we have a short PDF document that shows you additional steps.
The information on this page related to version 5.0.10 or higher.

Types of Manual Provisioning of the Snom phone

Each method of plug and play is described below. Before doing Plug and Play though, take a look at the pre-requisite steps .

  • DHCP, option 66 : This method can be used to provision in both LAN (internal) and WAN (remote) environments as long as you can control the local DHCP server and that DHCP server supports option 66. The phone retrieves its IP address and other configuration information through dynamic host configuration protocol (DHCP). In order to use this method, you need to put in the address of the PBX, either the IP-address or the DNS-address, along with the HTTP transport scheme (for example, " " or " ").


  • LAN provisioning : If your PBX is in the LAN and your phones are in the same LAN, then the PBX is smart enough to detect the make and the model of the phone (along with other efficient details) to present the user with an option of "setting up" the Phone to provision with a few clicks.


  1. If the "Setup" button doesn't come up (as above) that may mean one of the following:
  • PBX or the Phone is not on the same LAN as the other.
  • The MAC address that it detected is already being used by an extension under some domain.
  • Extension needs a factory reset to be fully functional at this point.
  1. If the above condition is satisfied, then the setup button appears and you can now assign that MAC address to an extension under a domain of your choice.
  2. This process handles the opening of the MAC Based provisioning, assigning the MAC address to the desired extension and actually provisioning the phone all by itself.
  • Manual setup : This method is done by accessing the phone through a web browser. You will need to configure the phone’s Settings URL setting so that the phone knows where the Vodia PBX is.
  1. The settings URL for the "Update " section of the Snom phone is: " http://pbx_domain_or_ip_address "
  2. Open the "MAC Based Provisioning" setting by selecting the extension.
  3. You can even assign the buttons to the individual phone or for the whole domain from under Domain> Advanced> Buttons
  4. Save this setting and "Reboot" the phone.

Auto provisioning the Snom phones (Needs a Hosted License only! )

With this PBX feature, you can easily redirect your snom phones to your Vodia PBX PBX for provisioning via the SRAPS server. It makes provisioning of Snom phones very easy. Ideally, all the user has to do is plug in his/her phone and he should be good to go. The phone should get all the settings, be registered and its buttons set, according to how they had been set up in the PBX.



Enter Username and Password for your SRAPS server here and save it.

2. Redirecting a Phone to the SRAPS server (Auto Provisioning)

After you have done the above step, you can redirect your snom phones. To redirect a snom phone to your Vodia PBX for provisioning, just add the MAC address of the phone (found on the phone label at the back) to the PBX:


  • Go to your selected domain in Vodia PBX web interface.
  • Go to the extension to which you want to bind your snom phone.
  • Go to the Registration tab of the extension found at the top.
  • Enter the MAC address of your snom phone in Bind to MAC Address setting.
  • Press Save .

This will not only bind the extension to that phone’s MAC address, it will also redirect that phone to your PBX when it requests for provisioning and will be provisioned by the PBX accordingly.

Syncing All MACs on the System

Generally, you won’t need this because when you add a MAC address for binding, it also automatically registers it with the snom provisioning server for redirection, according to the credentials and PBX address you have provided in the PnP Settings.

But if there were any MAC’s present on the system before you entered the PnP Settings for the Provisioning Server, those MAC’s would not have been redirected. For that or any other reason that some mac addresses are not redirected, you can redirect all the MAC’s on the system with a single press of the Sync button. It is found on the same page where you entered the provisioning server credentials.

Defining Which Firmware Should be Used

There have been many enhancements starting version 58.0. One of them was to subsidize the PNP section into text only. Today if you would like to change the firmware version, you will have to switch to admin-mode then navigate to Parameters, on the Type box edit the Firmware you would like to upgrade or downgrade to. You can see the URLs that correspond to each phone, you can change the link there or change the version number for example 8.4.35 to 8.5.36

Manual Provisioning

Steps :

  1. Add MAC address by clicking on the "+" button under "MAC " section under Extension's list.


  1. Enter the Manual provisioning URL as: "http://PBX_IP_OR_Domain_name"


  1. Select the Extension to open it up for MAC based Provisioning.


  1. You can even assign the buttons to the individual phone or, to the whole domain from under ```
    Domain> Advanced> Buttons.

  2. Save this setting and "Reboot" the phone.

  3. Reboot the phone.

NOTE: Provisioning may take approximately 2-5 minutes.
