How to Configure the Microsoft SIP Gateway with AudioCodes Analog Telephone Adapters

How to Configure the Microsoft SIP Gateway with AudioCodes Analog Telephone Adapters

Dust off your analog phones and connect them to Microsoft Teams! Through the power of Microsoft’s SIP Gateway, you can now connect your compatible analog telephone adapters (ATAs) and devices to Microsoft Teams.

Beginning in early 2023, SIP Gateway will support analog telephones, allowing you to use Teams calling functionality on the following compatible AudioCodes MediaPack analog telephone adaptor (ATA) models:

  • MP-112 FXS
  • MP-114 FXS
  • MP-114 FXS_FXO
  • MP-118 FXS
  • MP-118 FXS_FXO
  • MP-124 FXS
  • MP-1288
  • MP-202

Some use cases for SIP Gateway analog may include, but are not limited to:

  • Lift phones
  • Hotline phones (inbound only)
  • Taxi freephone handsets
  • Door access control phones

These use cases bring features like automatic dialing, which your ATA may already support, into the Microsoft Teams Phone ecosystem.

In order to use SIP Gateway analog, you must first enable and configure SIP Gateway in your Teams environment. If you haven’t already enabled this, check out Plan for SIP Gateway and Configure SIP Gateway before you continue. It’s important to point out that analog devices are only supported for Common Area Phone (CAP) accounts.

I’m using an AudioCodes MP-112 FXS for this “how to” guide, but the exact configuration steps may differ depending on the device.

Device Firmware


The supported firmware level for this device is 6.60A.367.001. To install the firmware:

  1. Log in to the web interface of the device.
  2. Open the Software Upgrade wizard by performing one of the following:
    • Select the Maintenance tab, click the Software Update menu, and then click Software Upgrade Wizard.
    • On the toolbar, click Device Actions, and then choose Software Upgrade Wizard.
      Software Upgrade Wizard
  3. Click the Start Software Upgrade. The wizard starts, requesting you to browse to a .cmp file for uploading.
  4. Click the Browse button, navigate to the .cmp file, and then click Load File. A progress bar appears displaying the status of the loading process.
  5. Click the Reset button to reset the device with the newly loaded .cmp file.
  6. After the device resets, the End of Process wizard page appears displaying the new .cmp file loaded to the device. Verify this by viewing the firmware version.

Setting the IP Address


The MediaPack series supports static IP addressing. Therefore, a proper working static IP address/netmask/gateway/DNS needs to be set up for the device to establish IP network connectivity prior to applying provisioning settings for SIP Gateway. AudioCodes provides some comprehensive guidance on this in their Quick Start Guide.

Configuring Provisioning Server URL


  1. Access the Admin Page by appending “AdminPage” to the device’s IP address in the Web browser’s URL. For example, http://10.0.0.100/AdminPage.
  2. Press ini Parameters on the left pane.

  3. Apply the following parameters, one by one:

Note:

    • The inifileurl parameter is different dependent on your region.
