Direct Routing allows you to connect Microsoft Teams to a range of telephony providers. This means being able to take advantage of cheaper call rates, more flexibility and better support.
Direct routing is seen as extremely attractive by a variety of businesses as it gives them the true flexibility of choosing their own telephony provider, but as direct routing is through certified Microsoft Partners, retain a verified integration with the Teams platform.
The idea of using Teams as a telephone system is a huge step forward for businesses who like the idea of Unified Communications – combining all their internal and external communications into one tightly-knit system.
Switching to Teams as a business telephone system doesn’t mean losing your old numbers. Keep your existing ones alongside any new DDI’s (Direct Dial in Numbers) you need.
