Introduction video summary here

Planning video summary here

This is short video at 3.5 minutes but lets see what we learn here about porting your existing conferencing telephone number to Audio Conferencing in Office 365.


This will explain the concept of porting phone number to Microsoft service


The first thing we need to consider with number porting is do we actually need to keep my existing phone number ? or would a new number be ok ?

If you have a conference bridge number you rarely use and plan to use Audio Conferencing for the first time / haven’t used it before then you may not need to port your existing conference bridge number it maybe better suited to have a new service phone number instead of porting.

If your ok with a new number go to SfB admin centre and voice and get a new service phone number and available immediately and available to your Conference bridge. using a new number means we dont have to port.


What happens if you have a very well known conference number and you want to keep your existing number when moving to Audio Conferencing in the Cloud ?

This is possible but you need to consider a number of points first !

  • 1st is the Audio Conferencing service from Office 365 available in the countries you required (Also not all of the countries have the ability to port so this must be checked)
  • 2nd – With number porting there will be a limited period of downtime but dependent on country and existing provider
  • 3rd – lead time for porting can take 1 week up to 4 month depends on country and provider

Before you start ports check existing provider and environment in your country how great the impact will be.

Once you know the possible

  • Downtime,
  • Lead time,
  • Availability

You can go to SfB admin panel and do a port request from there an example is below:


You can take the helm approach however this is only available for normal phone numbers NOT SERVICE NUMBERS.

For Audio Conferencing number porting we have to use SERVICE NUMBERS so we need to open a service request.

Ask the operator can you please port these numbers and they must be SERVICE numbers.

The operator will then help you out with the process.

Thats it and thank you.
