Pure IP —
Global Microsoft Teams Voice & Managed SIP Trunking

Pure IP is a certified Microsoft Teams Direct Routing provider that connects Microsoft Teams to the PSTN — enabling outbound and inbound calling from within Teams without deploying on-premises Session Border Controllers or relying on Microsoft Calling Plans. Direct Routing gives enterprises control over their PSTN carrier, number management, and call routing policies while keeping the Teams interface as the end-user calling experience. Pure IP manages the SBC infrastructure and PSTN connectivity on behalf of customers globally.

Operator Connect is a Microsoft-managed program that allows approved PSTN carriers — including Pure IP — to provision calling directly within the Microsoft Teams admin center without requiring customer-managed Session Border Controllers. Compared to Direct Routing, Operator Connect offers a simpler provisioning experience and closer Microsoft integration, as the carrier relationship is established through Teams Admin Center rather than via separate SBC configuration. Pure IP is an original Microsoft Operator Connect launch partner.

Pure IP provides PSTN coverage in over 100 countries, with local number acquisition, number porting, and emergency calling compliance in each covered market. For multinational enterprises standardizing on Microsoft Teams globally, this breadth of coverage enables a single provider to handle PSTN connectivity across regions that would otherwise require separate local carrier relationships in each country. Pure IP's global footprint is designed specifically for enterprises with international calling requirements.

Pure IP's managed SIP trunking delivers global SIP connectivity with a 99.999% availability SLA, local PSTN compliance across 100+ countries, and active management of the SIP infrastructure. Unlike unmanaged SIP trunks where the customer bears responsibility for configuration and troubleshooting, Pure IP's managed SIP includes proactive monitoring, SLA-backed uptime, and support from a team specializing in global enterprise voice. It is designed for organizations with complex, multi-country voice requirements that need carrier-grade reliability.

Pure IP's Global Voice Services provide international PSTN coverage for organizations that need to establish a local phone presence in multiple countries — including local number acquisition, number porting, toll-free numbers, and emergency calling compliance. The service is built for multinationals that need to present local caller ID in each market, receive local inbound calls, and comply with national emergency services regulations — all managed through a single provider rather than individual country-by-country carrier contracts.

Yes. Pure IP offers managed SD-WAN optimized for enterprise voice and unified communications performance — designed to complement their Microsoft Teams and SIP trunking services with network-level quality of service for voice traffic. For organizations standardizing on Teams globally, combining Pure IP's voice services with their SD-WAN ensures the network layer is optimized for real-time communications, reducing latency and packet loss issues that would otherwise degrade call quality on commodity internet connections.

Pure IP offers business SMS and digital messaging services that integrate with Microsoft Teams and other enterprise UCaaS platforms. This enables Teams users to send and receive SMS messages from within the Teams interface — without switching to a separate messaging application. For businesses that use Teams as their primary communications hub, SMS integration through Pure IP extends Teams into a complete business communications platform covering voice, video, chat, and text messaging.
