Was working with a customer today on enabling a site in the US and I hit a few snags that do not come into account when working on UK based sites.
Accept an enhanced emergency service disclaimer
I was getting a error in PowerShell which was stopping me from assigning the numbers to the users. To continue I have to run the below command to accept a disclaimer to allow me to continue
Set-CsOnlineEnhancedEmergencyServiceDisclaimer -CountryOrRegion US
Usage location conflicts with assigned emergency location
Use Get-CsOnlineLisLocation to identify the emergency location then enter
Set-CsOnlineVoiceUser -Identity email@example.com -TelephoneNumber +111111111 -LocationID [Enter location ID]
to assign the number and emergency location to the user in one command.
