Powershell Script - Skype for business unassigned number

Hi Team,

Good day!

I would just like to know if there is a Powershell script that assigns the unassigned number to a new user? I was trying to automate my SFB telephone number assignment to multiple users but I could not find a script that can do it.  

I would highly appreciate if you could share your sample scripts :-)

Thanks in advance!
