Access query

Hi.

Just a quick question i am hoping someone can answer.  I am currently working on call queues for a client and there is a requirement to divert calls to an external number. I know this cannot be done without some creativce account creation so i have set up a user account to use as a proxy to forward calls.  however when going into powershell I cannot set this user account up with enterprise voice as powershell isn't recognising the cmdlet 'Set-CsUser -Identity "user@domain.com" -EnterpriseVoiceEnabled $true...( i have a ready made script that works for all other clients i have worked with ) when checking the role of my account it is set to Teams Admin... I am used to having global admin so have not come across this before but is this issue caused by my account not having the correct role assigned?
