SECURE VOIP

Voice is traffic too. Secure it without strangling it.

Remote VoIP that doesn't backhaul, doesn't jitter, and doesn't route your calls through anyone else's infrastructure.

A man on a headset takes a video call while the encrypted voice path runs straight out to the people he is calling instead of through a concentrator.

Voice punishes backhaul.

VoIP (voice over IP, the phone system that runs on your network instead of a phone line) is the workload a VPN handles worst. Voice is brutally sensitive to delay: sending call traffic back through a concentrator and out again adds the lag and jitter users hear immediately, disconnect-and-reconnect cycles drop calls outright, and call quality sits at the mercy of whatever else shares the tunnel.

  • Leaving it exposed is not the alternativeTelephony systems are actively attacked for toll fraud and for interception, so an open PBX is the more expensive option, just later.
  • The infrastructure goes darkThe voice estate stops being addressable from the internet, the same way every other application behind the portal does.
  • Direct, and per sessionAuthenticated users and devices get their own tunnel straight to your voice infrastructure with no hairpin through a concentrator, which is why the latency case here is architectural rather than a tuning exercise.
  • The gate sits at registrationMFA and device checks run before a softphone registers, so a stolen extension is not a working one.
  • Privacy First counts double hereCall traffic never transits vendor machines, because there is no vendor machine in the path.

A tunnel carrying voice, and voice with its own path.

Both encrypt the call. Only one of them stops adding a hop to it.

  • Quality of serviceVoice gets its own per-session path; nothing else on the tunnel contends with it.At the mercy of whatever else is sharing the tunnel that day.
  • Call pathDirect to your own voice infrastructure, with no hairpin.Backhauled to a concentrator, then back out again.
  • Privacy exposureCall traffic flows direct and never touches vendor machines.The call transits the vendor's path along with everything else.
  • LatencyOne fewer hop by design, so the case holds without tuning.Extra hops add delay that callers hear in the first sentence.
  • DisconnectionsNo single tunnel to drop. Each session stands on its own.When the tunnel drops, the call ends with it.
  • User & device validationBoth the person and the device are validated before registration.The tunnel authenticates once, then trusts whatever is behind it.
  • MFAA second factor is enforced on the access itself.A tunnel carries traffic; checking factors is not its job.
  • IdP integrationRegistration is bound to the identity provider you already run.Voice users get managed alongside the tunnel, separately from everyone else.

Use cases

Give voice a direct path, not a longer one.

Call quality

Call quality survives security

Voice is the workload a VPN handles worst. Backhauling call traffic through a concentrator adds delay and jitter people hear inside a sentence, a reconnect cycle drops the call outright, and QoS is at the mercy of whatever else shares the tunnel. Per-session tunnels go direct to your telephony, so the latency case is architectural rather than something to tune.

OUTCOMES

Voice gets the securitywithout the delay.

What changes when the call path stops going through a concentrator.

Call quality survives

Security stops being the thing users can hear, because the path got shorter rather than longer.

Telephony goes dark

The voice estate leaves the internet, and toll-fraud scanners find nothing to register against.

Seats onboard normally

Remote agents and contact-centre seats join like any other user, on the same policies and the same portal.
