Buyer guide

For whom is CodeB Conference?

Six audiences who get value from CodeB today. For each: the problem they walk in with, the CodeB answer, why Zoom or Teams isn’t the right fit, and the deployment model that matches.

01 / Law firms

Privileged communication, on infrastructure you control.

The problem

Attorney-client privilege does not survive a vendor with overbroad data-processing terms. Discovery requests against the cloud video provider can erode confidentiality. Recorded depositions need defensible chain-of-custody — an unsigned MP4 from a cloud product is hard to authenticate in court.

The CodeB answer

The meeting platform runs on the firm’s own server. Media is peer-to-peer between participants with DTLS-SRTP encryption; nothing goes through a cloud media path. Every local recording carries an ECDSA-P256 cryptographic signature in a tamper-evident sidecar — a third party can verify the recording was not altered between capture and trial.

Why not Zoom / Teams

Both run media through vendor-managed cloud infrastructure with admin-analytics surfaces accessible to the vendor. Recordings are not cryptographically signed. Data-processing terms include broad rights to operational data the firm cannot fully audit.

Deployment

Single Windows server on-premise or in the firm’s private hosted tenant. SSO via the firm’s existing identity store (Active Directory / OIDC). Air-gappable for matter-isolated deployments.

02 / Clinics & healthcare

Telemedicine without sending PHI to a SaaS cloud.

The problem

Patient health information is regulated — GDPR Art. 9, HIPAA in the US, equivalent regional law elsewhere. Cloud video tools shift the controller/processor boundary in ways that make procurement and legal review expensive. EU healthcare providers face additional Schrems II concerns about US-hosted providers.

The CodeB answer

Patient audio and video never reach a third party. Meetings run on the clinic’s own server (or a private hosted tenant in a chosen jurisdiction). End-to-end DTLS-SRTP encryption between clinician and patient browsers. Retention is set by the clinic, not by the vendor; signed local recordings give a defensible audit trail.

Why not Zoom / Teams

Both require a BAA / DPA for healthcare use. Both add admin-analytics surfaces and metadata flows the clinic cannot fully suppress. Teams is welded to M365; using it for patient encounters drags the rest of the M365 estate into scope for healthcare-data review.

Deployment

On-premise Windows server in the clinic, or a private hosted tenant in the clinic’s jurisdiction. SSO against the clinic’s existing identity store. Optional CodeB Voice AI for appointment reminders — with on-premise AI Voice Engine fallback for clinics that cannot send caller audio to a cloud model.

03 / Public sector

Procurement-friendly. Air-gappable. Auditable.

The problem

Government and public-sector buyers face third-country-transfer rules, sovereignty-cloud requirements, fixed-budget cycles that don’t map well to per-seat SaaS, and auditor demands for source-level review of any system handling official communications. Most cloud video products fail at least two of these tests.

The CodeB answer

Runs entirely on the agency’s own Windows + IIS server. No hyperscaler dependency. Source code is open to inspection inside the customer’s organisation — auditors can read every C# handler, every JavaScript file, the entire TURN service. Air-gap deployment is supported with all dependencies served locally.

Why not Zoom / Teams

US-hosted by default; data residency in EU regions exists but doesn’t address Schrems II concerns. Per-seat licensing creates an annual budget line that recurs forever. Source is not available for audit. Many EU public-sector bodies have explicit guidance discouraging both.

Deployment

On-premise Windows server inside the agency’s network. Optional air-gap mode — fonts, signaling, TURN, ML models all served from the LAN. Single capex line item; no recurring per-seat fees.

04 / Hotels & reception desks

Front-desk telephony in a browser, AI after hours.

The problem

Hotel reception desks need a phone that lives in the front-desk browser tab, rings on the hotel’s SIP trunk, and doesn’t require a separate hardware phone or a SaaS UCaaS contract. After-hours coverage needs an AI receptionist that can take a reservation request or route urgent calls to the duty manager — without paying a third-party answering service.

The CodeB answer

The CodeB Phone PWA installs once on the front-desk computer and behaves like a desk phone — ringing on incoming calls, OS-level notifications, click-to-call. The CodeB Voice AI handles after-hours inbound: per-DID persona prompts, transfer to duty-manager mobile if the caller says "urgent," signed transcripts emailed to the manager next morning. Outbound AI can run wake-up calls.

Why not Zoom / Teams

Zoom Phone and Teams Phone bundle their own carrier service — the hotel already has a SIP trunk and doesn’t need a second one. Neither product’s AI assistant covers after-hours reception with a per-DID persona out of the box.

Deployment

Single Windows server on the hotel’s network or hosted by an IT partner. Registers as a SIP user on the hotel’s existing PBX (FRITZ!Box, 3CX, Yeastar, Asterisk, anything that speaks SIP). Front-desk staff just open the bookmark; no install for participants.

05 / IT providers & resellers

A turnkey video + AI voice layer for your existing PBX practice.

The problem

IT providers and MSPs who run PBX deployments for customers already have a SIP estate they manage. They’re losing video-meeting revenue to Zoom and Teams, and AI-voice revenue to standalone receptionist startups. Building either in-house is months of work; reselling someone else’s SaaS means margin sharing and no differentiation.

The CodeB answer

Deploy CodeB per-customer on Windows + IIS as a managed add-on. Customers get browser meetings, signed recordings, AI receptionist and outbound AI campaigns — all on the SIP trunk the reseller already manages. The reseller bills the customer for the deployment and ongoing operation; no per-minute margin shared with a SaaS vendor.

Why not Zoom / Teams

Both are direct-sale products; reseller margin is thin or non-existent. Neither integrates cleanly with the SIP trunks the reseller is already managing — they bring their own carrier service. No source access means the reseller can’t customise per-customer.

Deployment

Per-customer Windows + IIS install, often co-located with the customer’s PBX. The reseller may run multiple tenant deployments from one hosted Windows server (multi-tenancy by domain is the supported topology). White-label branding via per-tenant CSS.

06 / Organisations with existing 3CX / Asterisk / FRITZ!Box / FreePBX

Layer on. Don’t rip and replace.

The problem

The organisation already paid for its PBX. SIP trunks, extensions, call routing, voicemail — all working. What’s missing is modern web video, browser-based softphones for hybrid workers, optional AI receptionist on the inbound DID. Rebuying the entire telephony stack to add a video layer doesn’t make budget sense.

The CodeB answer

CodeB is a SIP client / bridge — it registers against the existing PBX as a regular SIP user (or multiple users, one per CodeB Phone account). The PBX stays in charge of routing, voicemail, recording policies. CodeB adds browser meetings, click-to-call, AI receptionist on top, without touching what already works.

Why not Zoom / Teams

Zoom Phone and Teams Phone want to replace the PBX with their own carrier service. For an organisation that already paid for FreePBX, 3CX, Asterisk or a FRITZ!Box, that’s a parallel telephony stack at extra cost. CodeB does the opposite — it integrates with what’s already there.

Deployment

One Windows + IIS server alongside the existing PBX. Configure CodeB’s SIP trunks to point at the PBX’s SIP interface. Tested against FRITZ!Box, 3CX, Asterisk and FreePBX; any standards-compliant SIP gateway should work. See the comparison page for a feature matrix.

Not sure which path fits?

If your organisation isn’t a clean match for any of the six above, we’re probably still useful — the underlying primitives (BYOC SIP, browser WebRTC, OIDC, voice AI) compose into a lot of shapes. A 30-minute call is faster than reading the rest of the site.
