Most partners sell Teams licences. Braintree brings the dial tone.

Braintree is one of nine Microsoft Managed Partners in South Africa. A reseller sells you the Teams Phone licence and leaves the operator side to a telco. Braintree runs both, Operator Connect or Direct Routing, the network design, the number porting and the 24/7 monitoring. One Microsoft Customer Agreement. One SA team. The licence and the dial tone, owned by the same people.

Teams Phone, end to end. Five parts. One identity.

Microsoft Teams Phone

Cloud PBX inside Teams. Inbound and outbound PSTN calls, queues, auto attendants, voicemail and recording. One identity across desk, mobile and meeting room.

The same number on every endpoint

Calling, meetings and chat in one app

Move a live call from desktop to mobile, no drop

Operator Connect

Microsoft-certified PSTN. Pick the operator in the Teams Admin Center. No SBC to deploy, no on-prem voice to maintain.

Direct Routing

SIP trunk and session border controller. The path when you need PBX coexistence, custom routing or specific in-country number ranges.

Admin and Analytics

Call queues, auto attendants, voicemail, compliance recording and call-quality dashboards. The voice side of the Teams Admin Center, governed.

Microsoft Purview

Data governance, lineage and POPIA-aligned cataloguing. Required for auditable AI on operational data.

Every stage. From current voice estate to live Teams calling.

From network readiness to a managed voice estate, the move to Teams Phone is organised by lifecycle stage. The first four get you live. The fifth is where the relationship begins.
01 · Readiness
Before a single number moves
Network and dial-plan assessment
Bandwidth, firewall ports, QoS and call-path tested. Dial plan, number-range mapping and licensing alignment. The Operator Connect or Direct Routing decision made on the evidence.
Current-estate audit
PBX contracts, SBC footprint, telco minutes and DDI ranges. What you run today, costed, before anything is replaced.
02 · Design
The path, on paper first
Call-flow and routing design
Auto attendants, call queues, emergency calling and after-hours routing designed against how the business actually answers the phone.
Number strategy
Porting plan for fixed-line and DDI ranges. ICASA lead times mapped. New ranges where porting does not fit.
03 · Pilot
Proven on a real group
Representative pilot
A user group across desks, mobile and meeting rooms. Call quality, devices and workflows validated on live numbers.
The gate
Rollout is gated on the pilot passing. Call-quality telemetry, not a thumbs-up, decides.
04 · Rollout
In waves, not a weekend gamble
Phased migration
By department or site. PBX coexistence where required. End-user enablement on calling, voicemail, queues and mobile.
Cut-over control
Numbers ported in planned waves. The old PBX stays live until each wave is proven on Teams.
05 · Operate
Where the relationship begins
Managed voice, 24/7
Call-quality dashboards monitored. Voice spend reviewed against the baseline monthly. Anomalous traffic flagged. One SLA, under the agreement.
Continuous optimisation
Devices, licences and routing tuned as the business changes. The monthly summary the CFO and the CIO both read.

Run by Braintree, monitored 24/7. On Microsoft Foundry where it helps.

Call-quality dashboards watched, voice spend reviewed against the baseline, anomalous traffic flagged. Where Microsoft does not ship a named agent, custom call-analytics and reporting on Microsoft Foundry and Power BI. SA-grounded. POPIA-aligned. The monthly summary the CFO and the CIO both read.

Discover, Evaluate, Deploy, Build.

Four stages. The readiness evidence first. The full TCO modelled. Cut over only where the case proves out.
01

Discover

Assess the network, the number ranges, the current voice spend and the PBX footprint. Map where Teams Phone carries the strongest TCO case.

02

Evaluate

Full TCO and payback model against the legacy estate, with the Operator Connect or Direct Routing recommendation. Presented to management. Sign-off before any cut-over.

03

Deploy

Pilot, then phased rollout on live numbers. PBX coexistence where required. Call quality gated on the pilot proving out.

04

Build

Custom call-analytics, reporting and routing automation on Microsoft Foundry where Microsoft does not ship a named one. Then managed, 24/7.

Braintree doesn't sell you Teams licences and leave. We bring the dial tone, then run it.

Operator Connect or Direct Routing. The fork is where you start, not where you land.

Different estates need different PSTN paths. Read the column that applies.

Operator Connect

Best fit. Most organisations. You want PSTN in Teams without running voice infrastructure, on a Microsoft-certified operator.

Direct Routing

Best fit. Organisations that need PBX coexistence, custom routing logic or in-country number ranges an operator cannot carry.

Most SA mid-market lands on Operator Connect. We assess the network and the number ranges before recommending one.

One Microsoft agreement. Not a vendor per layer.

Before. Licence here, minutes there, integrator in between.

What CIOs and CFOs ask before they book.

Operator Connect or Direct Routing. Which PSTN path fits us?
The honest rule of thumb. Operator Connect suits most organisations. You pick a Microsoft-certified operator in the Teams Admin Center, there is no session border controller to deploy and no on-prem voice infrastructure to maintain. Direct Routing is the path when you need PBX coexistence, custom routing logic or specific in-country number ranges an operator cannot carry. It uses a SIP trunk and an SBC, so it carries more control and more to run. We assess your network, your number ranges and your coexistence needs, then recommend one. Most SA mid-market lands on Operator Connect.
Yes, in almost every case. Fixed-line and DDI ranges port into Teams Phone. The SA-specific reality is lead time and process. ICASA rules, operator paperwork and cut-over windows mean porting is planned in weeks, not days, and run in waves over a weekend per range. Where a range cannot port cleanly, we map new ranges and a forwarding plan so no caller hits a dead number. The porting plan is part of the readiness review, costed and dated, before any cut-over.
Fair, and it is the first thing we test. Teams Phone call quality depends on the network path, not the Teams app. The readiness review measures bandwidth, jitter, packet loss and QoS end to end before a single user moves. We design the network for voice, set QoS policies, and validate on the pilot group on live calls. Call-quality telemetry runs from the moment each call connects, so a degradation shows on the dashboard before a user logs a ticket. We gate rollout on the pilot proving quality, not on a promise.
Emergency calling is configured per site and per user, mapped to a dynamic or static location so an emergency call routes correctly and carries the right address. This is part of the design stage, not an afterthought, because a mobile-first voice estate changes how location is determined. We document the emergency-calling design and test it before go-live. It is one of the checks that separates a properly deployed Teams Phone estate from a licence someone switched on.
Yes. Microsoft-certified Teams Rooms devices and handsets are part of the design. The meeting room dials out and receives calls on the same number plan as the desktop and the mobile app. Device choice, provisioning through Intune, and call-quality validation on room hardware are part of the pilot and rollout. One identity reaches the user whether they are at the desk, on the mobile app or in the boardroom.
The honest baseline first. PBX maintenance contracts, SBC licensing, telco minutes, line rental and the hardware refresh cycle, against Teams Phone licensing plus the calling plan or Operator Connect minutes. The saving is usually real, but it is specific to your estate, so we cost the baseline before we claim it. The softer case. One vendor instead of a PBX maintainer plus a telco plus an integrator. One bill, one SLA, one number that follows the user. We name the rand figure in the readiness review, not in the brochure.
Compliance recording, call analytics and voice telemetry sit in your Microsoft tenant, on Microsoft Azure South Africa where data residency applies, governed by Microsoft Purview retention and access policies. Braintree designs the recording and retention posture to your POPIA obligations and manages it from SA-resident workstations under POPIA-compliant access controls. A voice estate that records customer calls is a POPIA surface. We treat it as one, from the design stage.
Three answers. Credentials. Braintree is one of nine Microsoft Managed Partners in South Africa. 220+ SA clients. 100+ Microsoft-certified professionals. 10+ years on the Microsoft estate. Depth. We run the operator side and the user side, Operator Connect or Direct Routing, with the network and emergency-calling design a telco rarely touches. Continuity. Voice sits under the same One Intelligent Agreement as your Microsoft 365, security and support, run by the same SA team. A telco sells you minutes. A reseller sells you licences. Braintree brings the dial tone and runs it.
