Teams Phone adds external telephone calling to Microsoft Teams, so your staff can make and receive normal PSTN phone calls from within the Teams app, alongside chat and meetings. Effectively, it turns Teams into your business phone system, removing the need for a separate PBX. To call the outside world, Teams needs to be connected to the public phone network through a telecom partner.

There are three ways to connect Teams to the phone network. Direct Routing uses a partner's SBC and SIP trunk and gives the most control and flexibility — it's the most widely used approach in India. Operator Connect lets a participating operator provide calling integrated into the Teams admin centre for simpler management. Microsoft Calling Plans, where Microsoft provides the PSTN directly, have limited country availability. We help you pick the right model and partner.

Yes. Through a telecom partner you can provision new India DID numbers in the cities you need, and port your existing business numbers into Teams via Mobile/Number Portability, usually with little or no downtime. We coordinate numbering and porting as part of the setup so your customers keep reaching you on the same numbers.

Yes. In India, the PSTN breakout for Teams calls must be handled through a licensed Indian telecom operator — international toll bypass is not permitted — which is a key reason Direct Routing with an Indian operator is the common approach. Regulated businesses may also need compliant call recording. We match you to setups that respect these requirements. This is general guidance, not legal advice — confirm specifics with the partner and your advisors.

There are usually two parts: your Microsoft 365 / Teams Phone licences (billed by Microsoft per user), and the telecom partner's calling charges (per user and/or usage, plus numbers, SBC and recording). Our comparison surfaces the partner side so you see the calling cost clearly — figures shown here are illustrative.
