A grand link, by design
Distance should not feel like friction.
Global communication is rarely one straight path. Regulations change, carriers vary and customer expectations stay immediate. Granli turns that complexity into a dependable connection layer.
We combine programmable channels, route intelligence and hands-on operational care so teams can enter new markets without rebuilding the way they communicate.
Connected channels
One relationship, not four separate tools.
Design journeys across the channels your customers already use while Granli keeps identity, consent and delivery context aligned.
Voice
Cloud calling, number reachability and secure verification with clear quality signals.
Voice · OTP · SIPVideo
Embed real-time visual support and consultations into the moments that need human clarity.
WebRTC · Recording · RoomsOrchestration
Move between channels based on delivery, urgency and customer preference without losing the thread.
Routing · Fallback · EventsBuilt for builders
From first request to production traffic.
A consistent API, explicit delivery events and practical defaults keep implementation focused on your product, not telecom edge cases.
- Predictable REST resources and errors
- Event-driven delivery status
- Environment-aware credentials

Common questions
The practical details, upfront.
Start with the essentials, then bring us the route or workflow you need to solve.
01Can we start with one channel or market?
Yes. Most teams begin with one high-value journey, validate quality and compliance, then expand through the same integration.
02How does Granli choose a delivery route?
The platform evaluates channel availability, market rules, sender configuration and current route health. Fallback behavior is configured around your use case.
03Do we keep control of consent and customer data?
Yes. Granli provides transport and orchestration controls, while your application remains responsible for lawful collection and the customer relationship. Data handling is defined contractually.
04Can our team inspect message outcomes?
Delivery events and request identifiers make each accepted, delivered or failed signal traceable through your operational workflow.
05What support is available during rollout?
Granli supports solution design, route readiness and launch observation. The exact service model is agreed around traffic criticality and markets.
