Telephony & media
- Asterisk on a supported LTS branch
- PJSIP / SIP trunks and WebRTC endpoints
- ARI for call control and event handling
- ExternalMedia via WebSocket or a suitable media bridge
Technology
Keep the core.
Modernize the connections.
Asterisk remains the telephony foundation. Add voice AI, business integrations, and a measurable billing model around the infrastructure that already works.
Voice AI layer
- Streaming speech-to-speech agents
- Or an STT → language model → TTS pipeline
- Provider adapters and approved business tools
- Human handoff and failure recovery
Billing & mediation
- Call and session identifiers across services
- CDR / CEL events and provider usage records
- Separate supplier costs and customer tariffs
- Allowance, rounding, and minimum-charge rules
Integration & operations
- REST APIs and business event webhooks
- CRM, service desk, payment, and BSS / OSS integration
- Structured logs, metrics, and call tracing
- Access controls, secret storage, and deployment monitoring
This is the integration architecture we scope for a project. Compatibility, providers, supported versions, deployment, and delivery responsibilities are confirmed during technical discovery.
Build on documented
interfaces.
The Asterisk WebSocket media driver supports bidirectional media and removes the need for application-side packet timing in supported versions.
