Why Signals
Nigerian telephony, made usable by software.
Familiar Nigerian mobile numbers
Reach customers from familiar Nigerian mobile numbers without asking staff to call from personal lines.
One managed platform
Manage numbers, calls, usage and billing through one account and integration.
Numbers from multiple Nigerian providers can be purchased and managed through the same platform.
Real-time visibility
See call activity, usage and network performance while your workload is running.
Quality-managed infrastructure
Signals monitors customer access and prohibited traffic to protect number reputation, network quality and legitimate users.
For developers
Built for the way voice software already works.
Use a Twilio-compatible Voice API, control calls with OneML, receive webhooks and events, or connect an existing voice system over SIP.
OneML is Signals’ call-control markup language, derived from TwiML and compatible with supported TwiML applications.
