Private cloud telephony,
engineered in Rust.
The DaVinci VoIP System is the carrier-grade PBX behind Davinci Tech Solutions: multi-tenant SIP and WebRTC calling, PSTN trunking, ring groups, voicemail and recordings, all controlled from the customer portal.
Everything a modern phone system needs
Built for desk phones, the D Line mobile app and the browser phone, with the same routing rules everywhere.
Extensions & ring groups
Parallel and sequential ringing across desk phones, mobiles and browsers with per-tenant dial plans.
Secure by default
SIP over TLS and WebSocket Secure, SRTP media, TURN relay for strict networks and automatic certificates.
PSTN trunking
Inbound DIDs and outbound calling through redundant carriers, with caller ID and number rewriting per tenant.
Voicemail & IVR
Personal and group mailboxes, custom greetings, time-of-day rules and menu trees driven by the portal.
Recording & call history
Full-call recordings, detailed call records and media quality metrics on every leg, searchable in the portal.
Mobile push wake
Incoming calls wake the D Line app on iOS and Android through native push, so phones ring even when the app is closed.
One control plane, one media plane
Routing decisions live in the Davinci platform; this host handles signaling and media.
- Signaling: SIP over UDP, TCP, TLS and WebSocket Secure.
- Media: RTP and SRTP with a co-located TURN relay for NAT traversal.
- Routing: every call is resolved live against tenant rules in the Davinci API.
- Records: call detail records and recordings stream to the platform in real time.
