Two devices.
One private link.

Independent identities for Samsung and Moto. No SS7 access, IMEI, ICCID, cellular service or paid telephone number is required for this lab.

Identity compartment

Local test identity

GHOST Free = voice · Lite = basic messenger · Carrier numbers not connected

1 · Pair devices

Generate a private code on Samsung, copy it privately to the Moto. Same code and same profile on both devices.

Shared 26-character private code

Do not put the secret in an email subject, URL, screenshot or public log. A new code creates a new temporary room.

Automatic encrypted signaling endpoint (same on both phones)

Room offline

Default: dedicated CPX Neon Free signaling relay. The relay receives ciphertext envelopes and no pairing secret. Both phones must keep this page active during calls.

2 · Encrypted Wi-Fi call

Tap Call on Samsung. Moto receives an incoming prompt and must approve microphone access.

No incoming call

No active audio

Audio is WebRTC DTLS-SRTP with paired-code protected signaling. This is an unaudited alpha—not independently certified end-to-end identity verification.

3 · GHOSTmessenger / Lite lab

Messages remain on these devices and are not kept by the relay.

Data-channel messages have an additional AES-GCM application encryption layer. No offline delivery.

4 · Security & acceptance

Not tested

No automatic call data yet

Open 20-call acceptance console

I manually enabled airplane mode and re-enabled Wi-Fi

No sensitive device identifiers, GPS, contacts, SDP, ICE candidate addresses or call content are exported.

Zero-server alternative · Manual encrypted pairing

Manual fallback: this route uses no signaling server and no additional account. Transfer a large encrypted token between phones twice (offer, answer); afterward calling and messaging go directly device-to-device if the Wi-Fi network permits WebRTC.

Encrypted output token — copy to the other phoneEncrypted incoming token — paste from the other phone

Use the same private 26-character code on both phones, transmitted via a different trusted channel. The token encrypts SDP and ICE addresses. Manual mode is a lab-only fallback: no TURN relay, no background ringing, and not guaranteed across isolated Wi-Fi networks.

5 · Carrier coexistence & roadmap

Keep the current Straight Talk service. A native app may open Android eSIM management, but our GHOST calls do not depend on a SIM. Carrier APIs, multi-line routing, voicemail, CRM and mobile subscriptions remain a separate controlled phase.

911 is NOT supported. Use your existing carrier for emergencies.
