    Configuring a Cisco SPA 112/122 with a VoIPOffice extension

    Learn how to setup a Cisco SPA 112/122 with a VoIPOffice extension to enable reliable Voice over IP calls.

    The following guide is for configuring a Cisco SPA 112/122 with a VoIPOffice extension.

    You will need:

    • The VoIPOffice IP address – e.g. '77.240.xxx.xxx'
    • The Extension number – e.g. '1xxx'
    • The extension password/Secret (can be found by going to the edit mode of that specific extension, see the screenshot below)


    1-) Connect the adapter via the internet port to your router, using an Ethernet cable. 

    2-) Connect the adapter via one of the phone port to an analogue phone.

    3-) Once the adapter has been powered on, lift the receiver and dial **** for the configuration menu.

    4-) When 'Configuration menu' is heard, dial 110# to hear the IP address. Note it down.

    5-) On a computer connected to the same subnet as the adapter, open a web browser and type the full IP address (including the dots) into the address bar.

    6-) On the login screen that will appear, enter 'admin' (case sensitive) as both username and password.


    7-) Once you have logged in, you will see a screen like the one below:


    8-) From the menu select the 'Voice' Tab, then 'Line 1' from the left side menu. The main configuration settings will appear.


    9-) Enter the details as follow:

    Proxy and Registration:

    Proxy: The Voipoffice IP address / URL (e.g: 77.240.XXX.XX)

    Outbound proxy: leave blank 

    Use Outbound Proxy: No

    Subscriber Information:

    Display name: Extension Number (e.g: 1XXX)

    Password: The extension secret password (See the first screenshot on how to retrieve it)

    User ID: the Extension number (e.g: 1XXX)


    10-) If configured correctly, the configuration should look like this:


    11-) Click Submit and the Cisco will reboot.

    12-) Once this has been done, log into the voipoffice and go to the Monitor section: If the registration has been done correctly, the extension should appear as 'online'.
