When Teams Phone is a great fit
Teams Phone shines when you live in Microsoft 365 and your call flows are straightforward.
- Users primarily need internal calling + simple PSTN
- You want one app for chat, meetings, and calling
- You have limited need for complex queues/IVRs
When a hosted PBX wins
A PBX platform is often better for multi-site routing, complex IVRs, call center behaviors, and granular reporting.
- Advanced queues, IVRs, and after-hours routing
- Multi-tenant needs or multiple business lines
- Custom SIP integrations or SBC requirements
Hybrid options
Many SMBs end up with a hybrid: Teams for most users, PBX for reception/call-queues.
- Route main numbers to a PBX queue then to Teams users
- Keep analog/fax/door phones on the PBX
- Use SIP trunking to reduce PSTN costs
