- Do you wish to migrate PBX users from on-premises to the cloud?
- Do you want to keep or need to keep your current on-premises legacy PBX as a hybrid system to use loud UC as well?
- Does your current legacy PBX offer unique features that are critical to your business?
- Do some or all of your users need features that the Phone System does not currently provide?
Microsoft's Phone System technology allows Microsoft Teams to use PBX and call control features in the Microsoft 365 cloud.
The phone system is compatible with MS Teams clients and approved gadgets. You can use Phone System to replace your current PBX system with a set of services that are directly provided by Microsoft 365.
Internal calls within your company are handled only within the Phone System and never across the Public Switched Telephone Network (PSTN), eliminating the need for long-distance charges.
The phone system offers add-on options for connecting to the PSTN in order to place external calls.
You can link a supported, customer-provided Session Border Controller (SBC) to a phone system using Direct Routing.
Using this feature, you can set up on-premises Public Switched Telephone Network (PSTN) connectivity with the Microsoft Teams client.
