1. Create a .ps1 file using the script below

2. Create a CSV file where cells in column A each contain the IP addresses of Snom phones on your network(ex. A1=192.168.1.50, A2=192.168.1.51,...). It shouldn't cause any issues if you include IPs that aren’t snom phones, the script will just run a bit slowly. 

3. Update the script pathing to point to your CSV file

4. Reprovision phones to all use the same web page password. Current password in script: pG8nw6tcGNDS

5. Run the script in PowerShell. Ex. "C:\Users\Documents\SnomReset\TestSnom.ps1" -Update with the path to your .ps1 file

# Phone reset

$sites = Get-Content -Path 'C:\Users\chris\Documents\SnomReset\sites.csv' #Update with the path to your CSV IP file
