About Softtop

About Softtop — One Platform for Every
Business Communication

One platform for voice, messaging, global numbers, and AI-powered contact center — built for every business that communicates at scale.

Who We Are

One platform. Four pillars.

Headquartered in Hong Kong, serving 150+ countries with over a decade of experience. One platform — where most vendors need five.

Voice
Wholesale VoIP, SIP trunking, and CLI routes on direct Tier-1 interconnects.
Messaging
Bulk SMS marketing, SMS API, two-way SMS, and WhatsApp Business — all in one place. Widely used by retail and eCommerce teams.
Global Numbers
Local DIDs, toll-free, and virtual numbers across 100+ countries.
Cloud Contact Center
AI-powered omnichannel routing and real-time analytics on the same infrastructure.
Headquarters — Hong Kong
2/F TERN CTR Tower 1, 237 Queen's Road Central, Hong Kong. Our Hong Kong base gives us a direct routing advantage in Asia-Pacific — lower latency, higher ASR, and established Tier-1 carrier relationships across China, Japan, South Korea, Southeast Asia, and Australia that route locally rather than via US or European hubs.
What We Stand For

One platform. One SLA. One support team.

Every vendor you add is another contract, another support ticket, and another point of failure. We built one platform to change that.

99.999% uptime — contractually guaranteed

Not a marketing claim. Our SLA is backed by 70+ global Points of Presence and automated failover that reroutes traffic within seconds — no manual intervention required.

24/7 support staffed by engineers

When an enterprise contact center or a high-volume ITSP has a critical issue, they reach someone who can actually fix it — not open a ticket and wait.

Direct Tier-1 carrier interconnects

Not resold routes, not third-party aggregators. Fewer handoffs means better quality, lower latency, and no hidden intermediary failures.

What Drives Us

Four commitments we do not compromise on.

Reliability over promises.
Five-nines uptime is contractually guaranteed — not a marketing claim.
