Exploring PSTN Calling – Part 3 Transferring phone numbers to Skype for Business Online

21 Oct 2016 by Emma Robinson

Unless you’re in the process of setting up PSTN calling through Skype for Business for a brand-new business, it’s likely that you’ll need to transfer some existing phone numbers to the service. Here’s a quick guide on how to do this.
After the numbers have been ported, your service provider will change to Microsoft, and they will bill you for the usage based on the plan that you have.
Before you start:

  • There are certain numbers you cannot transfer:
    • Numbers that are used for data connections like for DSLs or broadband Internet connections.
    • Numbers that are dedicated to faxing (Faxing services are not available for Skype for Business, but if you transfer the phone number and assign it to a user then you will be able to use the number – but it will no longer work for any faxing services).
  • When you’re making the order, ensure that you have all the details for your current provider.
  • It is possible to transfer some or all of your existing phone numbers – it’s a little complicated, so here’s the Microsoft explanation: 

Full-port: This is when you transfer all of your numbers from your current service provider to Skype for Business Online. When you are asked for the phone numbers you want to transfer, you must include the billing telephone number along with all of the other phone numbers on your account. For example, let’s say your billing telephone number is +1 425-555-1234 and you want to port all of your 25 phone numbers (+1 425-555-1235 through 1259). When you follow the instructions below to transfer your numbers, you would enter: +14255551234 – +14255551259.
Partial-port: This is when you are only transferring some of your phone numbers from your current service provider to Skype for Business Online. When you want to port some of the phone numbers tied to the same billing telephone number, you must not include the billing telephone number along with all of the other phone numbers on your account. For example, let’s say your billing phone number (BTN) is +1 425-555-1234 and you want to port only 5 of your 25 phone numbers (+1 425-555-1235 through 1259). When you follow the instructions below to transfer your numbers, you would enter: +1 425 555 1235 – +1 425 555 1239.

  • It is important to ensure that all the information you provide for names, numbers and billing details are correct, otherwise this will hold up the progress of your number port.
  • Make sure the accounts and services are active, if they have been frozen then it will prevent the number port.

Next: Start the Port Order
If you have less than 999 numbers to transfer, then you can create a port order using the following steps. If your numbers exceed this, then you will need to do a manual port (guidance for this can be found here).

  1. Log into Office 365 with your admin credentials, and head to the Admin Center.
  2. Enter the Skype for Business section and click on ‘Voice’, then ‘Port orders’, and ‘Add’.
  3. Read the details on the ‘New Local Number Port Order’ and then click ‘Let’s get started’. port-order-start
  4. On the ‘Account info’, enter:
    • Account number for the service provider
    • Billing telephone number (which must be in a format with a + and country code before the number)
    • The PIN to unblock the number
    • Company name
    • Authorised user name
    • Address of the carrier/ service provider
  5. On the ‘Numbers’ page, enter the phone numbers that you want to transfer (with + and country code) – make sure you follow the instructions for either a partial or full port.
  6. IMPORTANT: Depending on what you have chosen to do. Then click either: ‘I am transferring all my numbers from my current carrier‘ or ‘I’m only transferring some of my numbers‘.
  7. Then click ‘Check number portability’, and ‘Proceed’.
  8. You will then be sent to the ‘Requested transfer date’ page, select the date and start time you need, then ‘Next’. port-order
  9. You will then be sent to a ‘Letter of Authorization’ – tick all of the boxes and in the signature section type the authorised user’s name, and click ‘Next’ again.
  10. Finally, on the ‘Submit’ page, you can enter the email addresses of anyone you wish to notify and then submit your port order.

You can view the status of your port order on the ‘Port Orders’ page, as well as any of the details.
Next Steps
You will be sent a confirmation email, showing the details of your order. Typically the order will take around 7-14 days to be processed, but it can take up to 30 days.
You will be notified of the order’s progress, as well as when the port is successful and the numbers ready. Then you should be able to get calling!
