Use this form to request that your meeting invitations have a dial-in phone number. By default all Skype for Business accounts are provisioned with the ability to host meetings, but not with a dial-in phone number. This means that all your participants must join the meeting with a Skype for Business client (mobile, web or software) from a PC, tablet, MAC or mobile phone. The ability to join the conference by dialing a phone number is not provided by default and must be requested via this form.
