What are you building?
Software products
Make calling part of the product you ship. Give users a way to make and receive calls, and keep the interaction inside your application.

What builders can do with the network.
The ambition
Make Africa’s telephone networks programmable.
Signals’ role
Signals gives your application access to numbers, calls, call control and events. Your team decides how the product works; Signals connects it to the telephone network.
We are building Signals to make that connection straightforward across African markets.
Build with Signals
Choose the interface that fits your build.
- Programmable Voice (Twilio Compatible) →
Make, receive and control calls with the Voice API, OneML and webhooks.
- SIP Access →
Signals SIP Access, our managed SIP trunking service, connects your voice application or AI stack to phone networks. Provisioning follows a technical review.
- Omni →
Bring completed-call events, call records and authorised recordings into your CRM, BI or internal systems. Your systems supply the analysis.
- Automations →
Turn business events into calls, capture keypad responses and return the outcome to your workflow.
A call becomes part of your application.
Your system starts the call. Signals handles the telephony. Call events return to your application so it can decide what happens next.
OneML is Signals’ call-control markup language, derived from TwiML and compatible with supported TwiML applications.

What to plan for in production.
An integration needs more than a successful first call. Review numbering, traffic, access controls, data handling and the support model as part of the build.
Security, data-protection and operating documentation is available whenever your team needs it. We can also review it with your engineering, security and operations stakeholders.
Security and compliance →Operating model →Request security pack →
- Visibility
- review call records, usage and network performance.
- Deployment
- confirm the architecture and provisioning path for your workload.
- Governance
