Often I need to find a certain LineUri in Lync. LineUris are most of the time configured on users, so a simple

Get-CsUser -filter {LineUri -like "tel:<e164number>*"}

will give you the result you are looking for. But a user is not the only object in Lync that can have a LineUri, and if you in addition don’t know what object has the LineUri you might need to search through all the objects. This script does just that. Sort of an opposite to Ståle Hansens List-UnusedNumbers.ps1.

The script will also list all objects that have that LineUri, so it is useful in the situations where you have managed to get the same LineUri on two objects and are getting “SIP/2.0 485 Ambiguous” errors on calls. Normally, if you try to give an object a LineUri that is already configured it will throw a powershell error, but there are situations where it doesn’t pick up on it, especially when using the ;ext=1234 addition to the LineUri.

Lync reports a SIP 485 Ambiguous and a Diagnostic ID 4199 "Multiple users associated with the target phone number" Lync reports a SIP 485 Ambiguous and a Diagnostic ID 4199 “Multiple users associated with the target phone number”
