Enterprise Voice Lync Projects Scripts Tools

Invoke-snomControl PowerShell GUI

While rolling out snom IP phones for a recent Lync enterprise voice deployment, I needed a way to control a phone while working remotely. Snom’s FAQ: provides details on this built-in functionality using the snom phone’s Web User Interface: and command.htm to simulate key presses.

After entering a few control commands into a browser and monitoring the phone’s display with my Get-snomScreen PowerShell GUI: Get-SNOMScreen. I figured there must be a better way!

Invoke-snomControl.ps1 is a PowerShell GUI script which allows remote control of a snom IP phone. Script is Code Signed using DigiCert.

  • Connect: Enter the snom phone’s web user interface information, select zoom level, reload interval and click start.

    • Requires network connectivity from computer running script to snom phone’s IP.
    • Account used to authenticate to web interface requires Admin mode on:
    • Recommend testing access to web interface prior to setting reload interval, reload set to “none” will make a single connection.
    • All parameters except reload interval can be adjusted while running.
    • Not limited to phones registered to Lync.
