Phone System for Teams Choice

With direct routing services from Blackstar Solutions, we’re giving you choice with Phone System for Teams.

We’re offering unique ways to deploy Phone System for Teams via Direct Routing Services. Direct Routing enables calling within the Microsoft Teams app to support your workforce wherever they are. It is also a cost-effective alternative to Microsoft Calling Plans.

Private or Cloud Hosted Session Border Controller

Direct Routing Services allows you to connect between your on-premise PSTN or SIP trunk and Microsoft Phone System for Teams. This is achieved using a physical or virtual Microsoft certified Session Border Controller (SBC) located either on-premise or in the cloud.

The SBC can be hosted to avoid purchasing and storing hardware on-site in three ways:

  • Privately hosted in our data centre
  • Cloud hosted
  • Your private network
