Now a days companies started looking for deploying or migrating enterprise voice system from their existing setup like Cisco call manager, etc to Lync servers or Skype for business servers. Finally they wanted to move to cloud PBX. It is because future is cloud. There are lot of guides and articles out there for setting up Enterprise Voice feature in on-premises servers. However not much information available to configure cloud PBX (Private Branch Extension) with PSTN (Public Switched Telephone Network) in Skype for Business online which is a part of Office 365 product.
This series is going to concentrate on how to setup enterprise voice feature in Skype for Business Online a.k.a SFB Online which is a part of O365.
- How to setup Enterprise Voice feature in on-premises servers
- Migrating the Enterprise Voice feature from on-premises servers to cloud PBX
- Creating a cloud connector by deploying basic SFB on-premises server to use the existing PSTN with cloud PBX
- Users are already in cloud with SFB license enabled (or)
- Users are in on-premises got synchronized with cloud and using SFB online
- Got Office 365 E1 or E3 or E5 licenses
- You are the global tenant administrator
- If you are going to port your existing number then need a recent bill which will have all the account information
We need to find our requirement like whether we need to enable both domestic and international calling features for the users or just a domestic is enough. Irrespective of this requirement we need to have cloud PBX is in place. At the time of writing this article, Cloud PBX is available by default with E5 license however we need to procure it as an Add-On features for E1 or E3 licenses. Additionally we need to also subscribe PSTN conferencing Add-on. To understand better I will list out the available Add-on specific to SFB online below which is available at the moment.
- PSTN Conferencing (dial-in conferencing) – This will help to use a phone to call in SFB meeting instead of using the computer audio
- Toll free numbers – As name suggest if we need to have toll free number then we need to have this add-on
- PSTN calling telephone service – If users wanted to call any phone numbers outside our O365 tenant then we need to have this feature
You can find more details about these Add-ons here.
Some of them might not enabled international calling feature but wanted to dial the international numbers at some point of time. If they have PSTN consumption billing in place then they can dial the international numbers with the subscriptions. They will be charged based on the number of units they have consumed. PSTN consumption can be used as a prepaid or postpaid service. If we add the fund manually it will be considered as prepaid and if we enabled auto charge option then it will be considered as postpaid service. The recommended will be postpaid.
If you are not sure about the consumption, I would suggest you to first go with auto charge option and monitor the consumption. Based on the consumption or if you wanted to restrict the unit to be used as per the business requirement then switch it to add fund which is like prepaid service.

We can use the portability feature to port our existing telephone numbers from different carrier to Microsoft or acquire new telephone numbers from them. I will cover this in this series.
