MOR and M4 SBC power VoIP businesses in 100+ countries. Billing, routing, compliance, and 24/7 support — built to handle real load, not demo environments.
From retail calling cards to wholesale carrier transit — Kolmisoft covers the full stack.
For retail and wholesale VoIP operators. Full billing, LCR, PBX functions, calling cards, resellers, recordings, and more. Up to 2,000 concurrent calls on multi-server.
For wholesale transit carriers. Handles massive call volumes with intelligent routing. Up to 10,000 concurrent calls and 1,000 CPS on multi-server architecture.
Developed and supported from Vilnius, Lithuania. No cracked software circulating in the wild. No language barrier when you need help fast.
Average support response during working hours is 15–20 minutes. For critical issues, 24/7 emergency support is available. Not a ticketing lottery.
MOR and M4 are built on real carrier feedback. If you need it, there's a good chance it's either already there or will be built — because you asked.
Hosted rental for flexibility. On-premise purchase for sovereignty. Either way, you get the same software, the same support, the same updates.
"Your system is really impressive. The more I look around in your system the more I am impressed. But I am just as impressed by your fantastic support — that is STATE OF THE ART."
"We are soooo happy with Kolmisoft and its team! Quick, professional and always listening to their customers. Kolmisoft is building a rock solid billing system. Keep up the good work."
"The ability to work with multiple asterisk servers at once is a great thing and relatively a cheap solution for mid size carriers. Asterisk doesn't crash and you've gone a long way with many other functions that do not exist on other systems."
"MOR is the most user friendly and powerful VoIP platform I know. We like Kolmisoft products for their very good quality/price ratio and support!"
Every call that routes through Kolmisoft is a carrier betting their revenue on your infrastructure. That's a trust problem — and Kolmisoft has been solving it since 2008.
