A new script has been added to the Lync Server PowerShell Scripts repository. This new script, cleverly titled Determine Whether or Not a Number has Been Assigned to a Call Park Orbit, will accept a number as input and will determine whether that number is within the range of any call park orbits defined within a Lync Server deployment. (See why we thought the title was so clever?) As with all the scripts in this repository, copy it and use it as is or customize it to suit your needs.
