"LoopUp really focuses on outcomes... support tickets and escalations have gone down by 80%, 75% reduction in administrative effort. Our telecom spend is down 75%."
"We expected equipment savings by moving to the cloud, but the savings, efficiencies and productivity gains that have come with LoopUp consolidation have exceeded our expectations."
"Working with LoopUp to consolidate a patchwork of regional telecoms vendors into a single global implementation has been a liberating experience."
"For the first time ever, we have worldwide visibility and management of all our phone numbers, all in one LoopUp portal that’s integrated with Teams."
Their architect on why the old telecom operating model could not keep pace, and why the large carriers could not fix it.
Provisioning down from two weeks to one day, support tickets down 80%, telecom spend down 75%, across 35,000 DDIs.
Large carriers focus on networks, contracts and services. Their architect on what a cloud communications partner did differently.

Microsoft Copilot and Teams AI work from what's in the Microsoft Graph: meeting transcripts, call recordings, conversation history. When telephony lives outside Teams, those calls stay dark: no transcript, no context, no intelligence.
Consolidating your global PSTN calling into Teams closes that gap. Every call becomes part of the record your AI draws from, and LoopUp does that with a single deployment, everywhere you operate.
Understanding your priorities, environment, scope and timing.
New numbers and porting - we handle it all. With proactive and quality communication.

LoopUp is a global provider of Microsoft Teams telephony. It gives multinational enterprises one contract, one management portal and one 24/7 support team to buy and manage PSTN calling in 100+ countries, using Operator Connect, Direct Routing as a Service and Bring Your Own Carrier (BYoC). LoopUp is a Microsoft Solutions Partner for Modern Work and is certified on Microsoft Operator Connect in 71 countries.
Cloud telephony delivers business phone calling from the cloud instead of on-premises PBX hardware. With Microsoft Teams it lets employees make and receive external phone calls in Teams via Operator Connect, Direct Routing or Microsoft Calling Plans. LoopUp provides a fully managed version that replaces legacy PBXs and regional carriers with a single global service.
Yes. LoopUp is a Microsoft-certified Operator Connect provider and also delivers Direct Routing as a Service and Bring Your Own Carrier (BYoC), turning Microsoft Teams into your global phone system. All numbers and users are managed in the LoopUp One portal, integrated with the Microsoft Teams Admin Center.
LoopUp provides cloud telephony in 100+ countries, with 71 available on Microsoft Operator Connect, including full PSTN replacement and local and toll-free numbers. Where regulation prevents direct PSTN replacement, LoopUp integrates local carriers (Bring Your Own Carrier - BYOC) and managed SBCs so all of your telephony stays under one global contract.
Yes. LoopUp consolidates fragmented regional carriers into one global contract, one pricing schedule, one 24/7 multilingual support team and one management portal. Honeywell reduced telecom spend and administrative effort by around 75% after consolidating with LoopUp (Oliver Anderson, Sr Solution Architect - Unified Communications & Collaboration, Honeywell Technologies).
Yes. LoopUp is a Microsoft-certified Operator Connect provider, live in 71 countries, the broadest Operator Connect coverage available: no operator offers Operator Connect in more countries, based on Microsoft's Operator Connect directory. Beyond Operator Connect, LoopUp also provides Direct Routing as a Service and Bring Your Own Carrier (BYOC), all under a single global contract and portal.
Both connect Microsoft Teams to the public telephone network. Operator Connect is a Microsoft-certified model that is quick to deploy and managed in the Teams Admin Center. Direct Routing, delivered as a service, adds flexibility and coverage for complex or highly regulated markets. LoopUp provides both, plus Bring Your Own Carrier (BYoC), under one provider.
Microsoft Teams Calling Plans are sold by Microsoft and can be assigned to users in around 34 countries and regions, with limited features and inflexible pricing. LoopUp provides managed Teams telephony in 100+ countries, with consistent global pricing, full number porting, local compliance and 24/7 multilingual support, all under a single contract.
Microsoft Copilot and Teams AI work from data in the Microsoft Graph, including call transcripts and recordings. When telephony sits outside Teams, those calls are invisible to AI. By consolidating global PSTN calling into Microsoft Teams, LoopUp makes every call part of the record your AI can draw from, deployed consistently everywhere you operate.
LoopUp provides enterprise-grade security and supports compliance requirements including call recording and data protection. LoopUp holds ISO/IEC 27001 and SOC 2 certification and runs a single global security review as part of one global contract.
LoopUp is used by multinational enterprises, including Fortune 500 organisations such as Honeywell, thyssenkrupp, Avison Young and Allegis Group. LoopUp has a 99.8% annual customer retention rate and more than 20 years of experience in enterprise voice.
LoopUp runs a proven five-stage process: discovery, number provisioning and porting, planning, go-live with testing and training, and ongoing 24/7 support. Rollout can be country-by-country or a single switch-on, on your timeline, backed by a 99.8% annual customer retention rate.
Yes. LoopUp covers China and India as part of its global Microsoft Teams telephony footprint. Both are highly regulated, so service is usually delivered through Direct Routing as a Service or Bring Your Own Carrier (BYoC) rather than Operator Connect. Numbers, users and support are still managed in the LoopUp One portal under one global contract.
LoopUp is a Microsoft-certified Operator Connect provider that also offers Direct Routing as a Service and Bring Your Own Carrier (BYoC), so one contract can cover countries inside and outside Operator Connect. It is designed for multinational enterprises that want one portal, one support team and one pricing schedule. Single-country operators and Microsoft Calling Plans remain alternatives where a single-market footprint is enough.
