Cryptographic SIP Digest Perimeter Gates
Every SIP registration and INVITE traverses Kamailio digest authentication with rotating nonces, TLS pinning, and automated perimeter revocation — unauthorized endpoints never reach media.

Infrastructure
Built on Raw Telecom Infrastructure
The features you feel every day are powered by hardened backend stacks we engineered and operate at the edge.
Instant FCM/APNs Device Wake Handshakes
Missed-call and voicemail events propagate through Redis hot-presence channels into sub-second FCM and APNs push frames, waking devices before the caller hears the second ring.
Autonomous Real-Time Margin Controls
Bridge orchestration continuously evaluates trunk cost, codec path, and LCR tables to route each leg through the lowest-latency, margin-positive path without human intervention.
When a call goes unanswered, our FreeSWITCH media engine records the message and our orchestration layer transcribes it and pushes a notification to your app instantly via FCM/APNs. You see a tappable list of messages — read the transcript or play the audio, no dialing in.
Yes. Pro and Enterprise plans enable multi-device syncing — your identity lives in our software core rather than on a physical SIM, so your number can register from several devices at once with Redis-backed presence.
Outbound calls are signed with STIR/SHAKEN identity tokens, and inbound calls are screened against a real-time CNAM directory with sub-millisecond cached lookups on Pro and above.
No SIM required. Vortex runs as a software client over Wi-Fi and data. Most modern iOS and Android phones work as-is. Porting is handled during signup.
On Pro and Enterprise, calls use HD wideband Opus audio end-to-end on our network, transcoded to standard codecs only when bridging to legacy carriers.
The Enterprise Suite exposes a Developer API for provisioning lines, routing rules, and messaging, plus webhooks for call and message events.
