Hosted PBX vs. Teams Phone

7 min read · Updated February 06, 2026

How to choose the right voice platform based on call flows, compliance, and budget.

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
