function Get-TeamsCLI {
  <#
  .SYNOPSIS
    Lists all Calling Line Identities by Name
  .DESCRIPTION
    To quickly find Calling Line Identities to assign, an Alias-Function to Get-CsCallingLineIdentity
  .PARAMETER Identity
    String. Name or part of the Calling Line Identity. Can be omitted to list Names of all Policies (including "Global").
    If provided without a '*' in the name, an exact match is sought.
  .EXAMPLE
    Get-TeamsCLI
 
    Returns the Object for all Calling Line Identities (including "Global")
    Behaviour like: Get-CsCallingLineIdentity, showing only a few Parameters
  .EXAMPLE
    Get-TeamsCLI -Identity ResourceAccount@domain.com
 
    Returns the Object for the Online Voice Route "ResourceAccount@domain.com" (provided it exists).
    Behaviour like: Get-CsCallingLineIdentity -Identity "ResourceAccount@domain.com"
  .EXAMPLE
    Get-TeamsCLI -Identity ResourceAccount*
 
    Lists Online Voice Routes with "ResourceAccount" in the Name
    Behaviour like: Get-CsCallingLineIdentity -Filter "*ResourceAccount*"
  .INPUTS
    None
    System.String
  .OUTPUTS
    System.Object
  .NOTES
    This script is indulging the lazy admin. It behaves like Get-CsCallingLineIdentity with a twist:
    If more than three results are found, a reduced set of Parameters are shown for better visibility:
    Get-CsCallingLineIdentity | Select-Object Identity, Description, SignInMode, HotDeskingIdleTimeoutInMinutes
