CodeB Sovereign Communications
Private browser meetings, browser phone and AI receptionist — on your own SIP infrastructure.
Conference · Phone · Voice AI · Identity · Wallet · API
EU-hosted, your tenant by default. One isolated tenant per site — on your own server or a private hosted tenant. Media and signalling stay on that infrastructure; external AI or messaging only when you switch it on.
CodeB adds WebRTC meetings, click-to-call, signed recordings, a PWA softphone and voice AI to the PBX or SIP trunk you already own. Self-host on Windows/IIS or run a private hosted tenant. No analytics. No SaaS media path. No forced carrier migration.
Built and operated by Aloaha Limited — shipping signing, PKI and secure-communications software since 2003. CodeB runs this phone system as the team's daily driver.

Browser-based video, audio, screen sharing and file drop — nothing to install. Works on Chrome, Edge, Firefox, Safari (iOS 14+) and Android Chrome.

Browser meetings + desk phone on top of the PBX you already own.
For organisations that already own their telephony (FRITZ!Box, Asterisk, FreePBX, Yeastar — anything that speaks SIP) and don’t want to send their calls through a SaaS cloud just to add video meetings. CodeB runs entirely on your own Windows + IIS server. No AWS, no Azure, no GCP, no SaaS middleman. GDPR-friendly by design. Air-gappable. Audit the source yourself.
CodeB Phone — a desk phone in your browser.
Install once, keep it open. It registers as a user, rings on incoming calls from teammates and the PSTN trunk, and stays out of your tab bar. Installable PWA · self-updating · OS-level notifications.
Sign a PDF in your browser — or from your backend.
Browser flow at sign.html assembles a PAdES-B-T signature with an RFC 3161 timestamp; the raw PDF never leaves the device — only the SHA-256 hash and the CMS bytes cross the wire. A Cloud Signature Consortium (CSC) v2 API at /csc/v2/… covers the same flow for programmatic clients, including a server-side signatures/signDoc path (§11.10) for batch jobs.
Every user gets an EC P-256 signing certificate enriched from their OIDC profile (CN / given / family / e-mail with SAN). Encrypted PDFs (RC4-128 & AES-128) supported. Prior signatures preserved via incremental save. Advanced Electronic Signature scope only — self-signed trust chain, not QES. Ready for European Digital Identity Wallet integrations.
Let a helper control your Windows PC — only when you allow it.
Aloaha RDPLauncher is a small Windows tray helper that joins CodeB meetings in its own window and adds consent-gated remote support: control only starts after you click Allow, or with a short access code you create and give out yourself. Ctrl+Alt+F12 stops it instantly. Also one-click Remote Desktop with DPAPI-stored logons. No installer · no admin rights · no telemetry.

Bring Your Own Carrier (BYOC) — PSTN without a separate telephony product
True BYOC SIP: inviting a phone number to a meeting works against your existing SIP trunks. No Zoom Phone, no Teams Phone, no extra license. Multi-trunk with priority and failover — the same carriers you already pay for handle inbound and outbound.
Add a phone to an ongoing meeting in one click
Mid-call, press Dial phone, type a number — the SIP bridge calls them in. They appear as a tile alongside the video peers. Useful when someone unexpected needs to be pulled in without anyone leaving the room.
Click-to-call from any web page
One <script> tag on a customer-facing site → floating button → visitor lands in a meeting room → SIP bridge dials your office. The real phone number never appears in the HTML; an unguessable alias does the routing.
Frequently asked questions
What is CodeB Sovereign Communications?
CodeB Sovereign Communications adds WebRTC meetings, click-to-call, signed recordings, a PWA softphone and voice AI to the PBX or SIP trunk you already own. CodeB can be self-hosted on Windows and IIS or run as a private hosted tenant. There is no analytics, no SaaS media path and no forced carrier migration.
Who makes CodeB?
CodeB is built and operated by Aloaha Limited, which has shipped signing, PKI and secure-communications software since 2003. The Aloaha team uses the CodeB phone system as its daily driver.
Do I need to install software to join a CodeB meeting?
No. CodeB meetings run in the browser with video, audio, screen sharing and file drop, and nothing to install. Supported browsers are Chrome, Edge, Firefox, Safari (iOS 14+) and Android Chrome; camera and microphone access is required. Guests can join anonymously with a room code, or sign in with CodeB.
Does CodeB work with my existing PBX such as FRITZ!Box, Asterisk or FreePBX?
Yes. CodeB is built for organisations that already own their telephony, including FRITZ!Box, Asterisk, FreePBX, Yeastar or anything else that speaks SIP. CodeB adds browser meetings and a browser desk phone on top of that PBX instead of replacing it.
Does CodeB need AWS, Azure or another cloud?
No. CodeB runs entirely on your own Windows and IIS server, with no AWS, no Azure, no GCP and no SaaS middleman. CodeB is air-gappable, and you can audit the source yourself.
Is CodeB GDPR-friendly?
CodeB is described as GDPR-friendly by design. Media stays peer-to-peer with end-to-end DTLS-SRTP encryption, data residency stays under your control, and there is no analytics and no telemetry. There is no hyperscaler dependency.
What does Bring Your Own Carrier (BYOC) mean in CodeB?
BYOC in CodeB means that inviting a phone number to a meeting works over your existing SIP trunks, with no Zoom Phone, no Teams Phone and no extra license. CodeB supports multiple trunks with priority and failover, so the carriers you already pay for handle inbound and outbound calls.
Can I add a phone caller to a meeting that is already running?
Yes. During a CodeB meeting you press Dial phone and type a number, and the SIP bridge calls that person into the room. The phone participant appears as a tile alongside the video participants, so nobody has to leave the meeting.
How does the CodeB click-to-call widget work?
The CodeB click-to-call widget is added to a web page with one script tag and shows a floating button. A visitor who clicks lands in a meeting room and the SIP bridge dials your office. The real phone number never appears in the HTML, because an unguessable alias does the routing.
What is the CodeB AI Digital Receptionist?
The CodeB AI Digital Receptionist is a real-time voice AI that answers a phone number you point at CodeB. The receptionist speaks any language, follows your script, takes messages, transfers to staff and emails you the transcript. You can try the receptionist from your browser with no install.
What is CodeB Phone?
CodeB Phone is a desk phone in your browser, installed once as a PWA. CodeB Phone registers as a user and rings on incoming calls from teammates and the PSTN trunk. The app is self-updating and uses OS-level notifications.
Can CodeB sign PDF documents?
Yes. The CodeB browser signer at sign.html creates a PAdES-B-T signature with an RFC 3161 timestamp, and the raw PDF never leaves the device; only the SHA-256 hash and CMS bytes cross the wire. A Cloud Signature Consortium (CSC) v2 API covers the same flow for programmatic clients. The scope is Advanced Electronic Signature with a self-signed trust chain, not QES.
Does CodeB support remote support of a Windows PC?
Yes, through Aloaha RDPLauncher, a small Windows tray helper that joins CodeB meetings. Remote control only starts after the user clicks Allow or shares a short access code they created, and Ctrl+Alt+F12 stops control instantly. RDPLauncher needs no installer, no admin rights and has no telemetry.
How is CodeB different from Zoom and Microsoft Teams?
CodeB brings PSTN into meetings over your own SIP trunks without a separate Zoom Phone or Teams Phone licence, lets you add a phone caller mid-meeting, and offers a click-to-call widget for any web page. CodeB also runs on your own server rather than a vendor cloud. A full comparison with Zoom and Teams is on the CodeB comparison page.
How do I buy or host CodeB?
CodeB can be self-hosted on your own Windows and IIS server or run as a private hosted tenant. The Buy / host page describes both options, and a live demo is linked from this page; guests can also join a meeting anonymously.
