Create organisational SIP enabled Contacts

Hi All,

I know this might seem quite a specific task but I have a very large client that would like to have the ability to create SIP enabled contacts at an organisational level in Azure AD which is not Synchronized from on-premise AD.

We can create mail enabled contacts using the Exchange PowerShell commands New-MailContact but we can't add the SIP address so it will show in the list of contacts from within Skype for Business Online/Teams.

We have looked into the Microsoft Graph API but there is no option to add a organisational SIP contact.

I have asked the question in the Skype for Business forum and I have been pointed to this forum to give it a try.

Thanks,

Dan
