There are two types of Models to get started with Microsoft Direct Routing experience:

  • The enterprise Model

The Enterprise Model

Companies having existing on-premises hardware for their current phone systems must opt for the Enterprise model to set up Teams Calling solution.  The Session broadcast controller is connected to an Office 365 tenant. You’ll need an Office 365 enterprise subscription (through E1, E3 or E5), a Microsoft Audio Conferencing license (required to enable external participants to schedule Teams meetings) and a phone system license. Users with additional license for the Microsoft Teams Calling Plan are also supported by Teams Direct Routing solution.

The infrastructure requirements include: a qualified Session broadcast Controller, established connection with the SCB Microsoft Teams SIP proxy (you must have SIP signaling port, fully qualified domain name (FQDN), certificate for the SBC, public IP address for the SBC and public DNS entry for the SBC). In addition to this, a solid connection between SIP trunk or legacy PRI to the SBC.

The Carrier Hosting Model

The Carrier Hosting Model is most appropriate when there is no existing phone system in your organization. You have the authority to choose the Direct Routing SBC provider and a carrier’s SBC would be paired with Office 365 domain and then further tied to multiple Office 365 tenants via subdomains. Every customer is provided a unique SBC FQDN. Further, a wildcard certificate covering the carrier base domain is needed and organizations would have to setup configuration once per tenant.

For the licensing and infrastructure requirements, companies would need a third party carrier’s subscription and check out what are your billing options like pay-as-you-go, toll-free, flat rate, or an option bundled with other subscriptions. In addition to that, you would need Records for SBCs in your DNS zone.
