$header = @{Authorization = "Bearer $token"}

#Get id of the Speed Dial list.

#Number to Add. MRI is the phonenumber of the contact, same as phone property. If contact to be added is a internal user, add the request like this:
#{"add":[{"mri":"8:orgid:18c4a91b-4fa9-4fbd-ab1c-b39465d81baf","displayName":"Admin","isFederated":false,"email":"brumunddal@alexholmeset.onmicrosoft.com"}]}
#To find the org id, run this command and look for it in a users buddies list:
#(Invoke-RestMethod -Uri $URL  -Method GET -Headers $header -ContentType "application/json").value
$payload1 = @'
{"add":[{"mri":"4:123456789","displayName":"Helpdesk","phone":"123456789","companyName":"Contoso","jobTitle":""}]}

'@

#Add phonenumber 2 to Speed Dial list.
