function Test-TeamsUserVoiceConfig {
  <#
  .SYNOPSIS
    Tests whether any Voice Configuration has been applied to one or more Users
  .DESCRIPTION
    For Microsoft Call Plans: Tests for EnterpriseVoice enablement, License AND Phone Number
    For Direct Routing: Tests for EnterpriseVoice enablement, Online Voice Routing Policy AND Phone Number
  .PARAMETER UserPrincipalName
    Required for Parameterset UserPrincipalName. UserPrincipalName or ObjectId of the Object
  .PARAMETER Object
    Required for Parameterset Object. CsOnlineUser Object passed to the function to reduce query time.
  .PARAMETER Partial
    Optional. By default, returns TRUE only if all required Parameters are configured (User is fully provisioned)
    Using this switch, returns TRUE if some of the voice Parameters are configured (User has some or full configuration)
  .PARAMETER IncludeTenantDialPlan
    Optional. By default, only the core requirements for Voice Routing are verified.
    This extends the requirements to also include the Tenant Dial Plan.
    Returns FALSE if no or only a TenantDialPlan is assigned
  .PARAMETER ExtensionState
    Optional. For DirectRouting, enforces the presence (or absence) of an Extension. Default: NotMeasured
    No effect for Microsoft Calling Plans
  .EXAMPLE
    Test-TeamsUserVoiceConfig -Object $CsOnlineUser
    Tests a Users Voice Configuration (Direct Routing or Calling Plans) and returns TRUE if ANY configuration is found
    To reduce query time, the CsOnlineUser Object can be passed to this function
  .EXAMPLE
    Test-TeamsUserVoiceConfig -UserPrincipalName $UserPrincipalName
    Tests a Users Voice Configuration (Direct Routing or Calling Plans) and returns TRUE if FULL configuration is found
  .EXAMPLE
    Test-TeamsUserVoiceConfig -UserPrincipalName $UserPrincipalName -Partial
    Tests a Users Voice Configuration (Direct Routing or Calling Plans) and returns TRUE if ANY configuration is found
  .EXAMPLE
    Test-TeamsUserVoiceConfig -UserPrincipalName $UserPrincipalName -IncludeTenantDialPlan
    Tests a Users Voice Configuration (Direct Routing or Calling Plans) and returns TRUE if FULL configuration is found
    This requires a Tenant Dial Plan to be assigned as well.
  .EXAMPLE
    Test-TeamsUserVoiceConfig -UserPrincipalName $UserPrincipalName -Partial -IncludeTenantDialPlan
    Tests a Users Voice Configuration (Direct Routing or Calling Plans) and returns TRUE if ANY configuration is found
    This will treat any Object that only has a Tenant Dial Plan also as partially configured
  .INPUTS
    System.String
  .OUTPUTS
    Boolean
  .NOTES
    Can be used providing either the UserPrincipalName or the already queried CsOnlineUser Object
    All conditions require EnterpriseVoiceEnabled to be TRUE (disabled Users will always return FALSE)
    Partial configuration provides insight for incorrectly provisioned configuration.
    Tested Parameters for DirectRouting: EnterpriseVoiceEnabled, VoicePolicy, OnlineVoiceRoutingPolicy, OnPremLineURI
    Tested Parameters for CallPlans: EnterpriseVoiceEnabled, VoicePolicy, User License (Domestic or International Calling Plan), TelephoneNumber
    Tested Parameters for SkypeHybridPSTN: EnterpriseVoiceEnabled, VoicePolicy, VoiceRoutingPolicy, OnlineVoiceRoutingPolicy
  .COMPONENT
    VoiceConfiguration
  .FUNCTIONALITY
