Operator Connect vs Direct Routing for Teams Phone 2026

Microsoft sells its own Calling Plans, and for a small single-country team they can be enough. At enterprise scale, three problems appear quickly.

First, coverage. Microsoft Calling Plans are not available in every country, and number portability and local DID availability are limited across much of Latin America. Enterprises with offices in Bogotá, Mexico City, São Paulo, or Panama often cannot get the local numbers and regulatory compliance they need from a single global plan.

Second, cost and flexibility. Per-user, per-minute bundles rarely match real calling patterns. Organizations with high outbound volume, contact centers, or existing carrier contracts usually pay more than they would with SIP trunking and managed voice traffic from a specialized operator.

Third, reliability and control. Native plans offer little visibility into call routing, failover, or quality of service. Mission-critical voice needs carrier-grade uptime — the 99.999% availability that native licenses rarely guarantee — plus the ability to route traffic intelligently and keep numbers when providers change.

This is the core challenge Operator Connect and Direct Routing solve: they let enterprises bring their own carrier and connectivity to Teams instead of being locked into one global plan. The question is not whether to extend Teams Phone, but which model delivers the coverage, economics, and resilience your organization actually requires.

How Operator Connect works. You select a participating operator from the Teams Admin Center, the carrier provisions phone numbers and voice service over a peering connection managed by Microsoft and the operator, and numbers appear in your tenant ready to assign to users. There is no SBC to buy, configure, or patch. The carrier owns the infrastructure and SLAs, which makes Operator Connect the fastest path to enterprise calling and the easiest to operate.

How Direct Routing works. A Session Border Controller — deployed on-premises or, more commonly today, as a cloud service managed by your provider — sits between Teams and the carrier's SIP trunk. Calls flow from Teams to the SBC, across the SIP trunk to the PSTN, and back. Because you control the SBC and dial plans, Direct Routing supports complex routing, analog device and contact-center integration, least-cost routing across multiple carriers, and granular policy control.

Choosing between them. Operator Connect favors simplicity and speed; Direct Routing favors flexibility and control. Many enterprises run a hybrid: Operator Connect for straightforward markets and Direct Routing where they need local numbering, custom routing, or multi-operator managed connectivity. A managed provider can deliver either model — or both — as a fully operated service, removing the burden of running SBCs and carrier relationships in-house.

Extending Teams Phone with Operator Connect or Direct Routing delivers measurable advantages.

Lower total cost of ownership. Bringing your own carrier replaces premium per-minute bundles with competitive wholesale rates and consolidates collaboration and telephony onto one platform, reducing duplicate licensing and legacy PBX maintenance.

Carrier-grade reliability. A managed model targets 99.999% uptime with redundant SBCs, automatic failover, and proactive monitoring backed by managed IT and infrastructure services — far beyond what native licenses guarantee.

Global reach with local compliance. Enterprises gain local numbers, emergency-calling compliance, and number portability across Latin America, the US, and Europe from a single partner, instead of stitching together one plan per country.

Scalability and control. Adding users, sites, or whole countries becomes a configuration change rather than a procurement project. Direct Routing in particular gives administrators the routing logic, analytics, and contact-center integration that growing organizations need.

Security and compliance by design. Routing voice through a managed provider lets enterprises enforce encryption, real-time toll-fraud monitoring, and regional data-residency rules that scattered native calling plans cannot. As voice increasingly becomes a target for fraud and interception, pairing connectivity with a provider that also delivers managed cybersecurity keeps your communications protected end to end.

One unified experience. Employees keep working inside Teams — the same app for chat, meetings, and calls — on any device, anywhere. That consistency improves adoption and productivity while IT manages a single, secure communications stack.

Together, these benefits explain why most enterprises in 2026 keep Teams for collaboration but connect it to the PSTN through a specialized operator rather than a one-size-fits-all global plan.

With more than 30 years of experience in enterprise telecom across Latin America, the US, and Europe, HIT Communications delivers Microsoft Teams Direct Routing and operator-grade calling as a fully managed service. We connect your Teams tenant to the public telephone network with carrier-grade SBCs, local numbering in the countries where you operate, and SLAs built for mission-critical voice.

Because HIT operates its own voice network and carrier relationships, we can deploy Operator Connect-style simplicity or fully customized Direct Routing — or a hybrid of both — tailored to each market you serve. Our team handles SBC provisioning, number porting, dial-plan design, failover, and 24/7 monitoring, so your IT staff manages users in Teams instead of telecom plumbing.

For multinational organizations, that means one partner for connectivity, voice, and support across every region, with consistent quality and a single point of accountability. Whether you are migrating from a legacy PBX, consolidating multiple UCaaS tools, or rolling out Teams Phone for the first time, HIT provides the connectivity backbone that makes enterprise calling reliable, compliant, and cost-effective.

In 2026, Microsoft Teams is the collaboration hub for hundreds of millions of workers — but turning it into a true enterprise phone system depends on the PSTN connectivity behind it. Operator Connect offers speed and simplicity; Direct Routing offers control and flexibility; and for most multinational enterprises, a managed combination of the two delivers the best balance of cost, coverage, and reliability.

The right partner removes the complexity. To map out the ideal Teams calling architecture for your organization — across Latin America, the US, and Europe — contact the HIT Communications team for a tailored assessment. The next step toward unified, carrier-grade enterprise voice starts with a single conversation.
