| What matters | Legacy PBX plus telco | Teams Calling with Braintree |
|---|---|---|
| One identity | Desk phone, mobile and softphone are separate numbers and systems |
✓
One number across desk, mobile app and meeting room
|
| Mobility | Calls tied to the desk. Forwarding and second SIMs to reach people |
✓
Move a live call from desktop to mobile with no drop. Reachable anywhere
|
| Vendors | PBX maintainer plus telco plus integrator. Finger-pointing on a fault |
✓
One SA team owns the call end to end. Microsoft-direct escalation
|
| Data residency | Recording and call data wherever the PBX or telco platform runs |
✓
Recording and telemetry on Microsoft Azure South Africa. POPIA-aligned
|
| Cost shape | PBX maintenance plus SBC plus telco minutes plus line rental |
✓
Teams Phone licensing plus Operator Connect minutes, under one agreement
|
| Hardware | Existing handsets keep working until they fail | Some device refresh to Teams-certified hardware over time |
| 5 to 1 in Braintree's favour. Legacy PBX wins on sweating old hardware. Honest. | ||
