Wholesale VoIP for Tier-2 Providers

Built for the Real Backbone of Telecom

Wholesale VoIP is a tough business. Margins are thin, competition is fierce, and Tier-1 providers demand accuracy, compliance, and automation.

That’s why Kolmisoft built MOR and M4 specifically for Tier-2 providers — companies like yours who connect to Tier-1 carriers, manage complex routes, and sell services to resellers, ITSPs, and enterprises.

Why Tier-2 Providers Choose Kolmisoft

  • Carrier-Grade Reliability – trusted by providers worldwide.

  • Tailored for Tier-2 Needs – not a generic PBX, but a wholesale-first platform.

  • Profit Protection – prevent margin loss with precision billing and routing.

  • Compliance & Security – meet strict Tier-1 and regulatory requirements.

  • Automation at Scale – save hours every week on tariffs and routing.

Solving the Pain Points of Wholesale VoIP

  • Complex Tariffs – Tier-1 providers like Deutsche Telekom send massive, inconsistent lists. Our Automated Rate Import handles them in minutes.

  • Billing Mismatches – if Tier-1 bills you by CalledID and you don’t, you lose money. Our Billing by CalledID feature ensures perfect alignment.

  • Number Portability – prefixes no longer guarantee the operator. Our MNP lookups prevent routing errors and margin loss.

  • Compliance Pressure – U.S. and Canadian calls require STIR/SHAKEN. We’ve built it in, so your traffic won’t be blocked.

  • New Revenue Streams – with Flash Calls and WebRTC, you can sell innovative services to enterprises and app providers.

Designed to Help You Compete & Grow

Kolmisoft is not just another softswitch. It’s a complete business platform for Tier-2 providers, giving you the same tools, automation, and compliance that Tier-1 carriers demand — at a fraction of their cost and complexity.

With Kolmisoft, you can:

  • Connect confidently to Tier-1 carriers.
