Port a Phone Number to Cloud PBX in Office365
This is an overview of the experience for porting (moving) an existing office telephone number from an existing telephony carrier to Skype for Business Online.
Skype for Business Online in Office365 offers PSTN Calling as part of the Cloud PBX feature set. PSTN calling allows a user to place and receive calls to the Public Switched Telephone Network with enterprise PBX functionality. When provisioning a user for this service, the Office365 administrator can either purchase telephone numbers directly from Microsoft or port an existing telephone number from an existing carrier to Office365. I covered the process for purchasing telephone numbers in a previous blog post: How to Enable Cloud PBX & Modern Voice
Before you Begin: Gather the following information:
- Account Number from existing carrier
- PIN (if required by carrier)
- Billing telephone number
- Service Address (located on bill from carrier)
- City/State/Zip of the billing address
- Range of telephone numbers to port
- Emergency addresses for each user the ported number will be assigned to
Note: This is assuming other requirements have been met for Cloud PBX and PSTN Calling in the Office365 tenant. For more information, please reference my previous blog post: How to Enable Cloud PBX & Modern Voice
Important: If you plan on porting more than 999 phone numbers, review Manually Submit a Port Order Request.
Important: See if your carrier is supported prior to proceeding with the process. Refer to What phone service providers or carriers are supported for more information.
