To successfully port your Skype for Business (Office 365) phone number to OnSIP, you will need to create a Skype port out PIN using the Skype for Business admin center. The PIN is typically 6-10 digits and managed in the Voice > Port orders section of your Skype for Business portal.
After you set a Skype PIN, you will need to provide it to our porting team to be included in the port request. You can provide us with the PIN when submitting your port request, or when returning your signed LOA (authorization) form.
In place of a traditional bill copy, you can supply OnSIP with screenshots from your Skype web portal showing the phone numbers to be ported, the name and the address on the account. The number you are porting out can be used as the BTN (Billing telephone number).
Note: We make every attempt to work with all telephone service providers. However, certain local or regional guidelines may preclude your current provider from releasing your number.
