Your calls, on an engine we wrote, in a jurisdiction no foreign order reaches.

A back-to-back user agent we wrote ourselves, carrying real traffic today. Both legs of every call terminate on the engine, so the platform controls the media rather than watching it pass.

The production switch serves SIP on UDP and TCP port 5060 and on TLS port 5061, so a desk phone, a carrier and an encrypted client each have a way in.

SIP over WebSocket on the switch, published as WSS, which is the transport a browser or a mobile client connects on without a VPN.

Persistent TCP trunks with keepalive, dead-peer detection, exponential-backoff reconnect and in-place re-authentication on the same socket.

PRACK and 100rel, UPDATE and OPTIONS keepalive, FQDN trunk resolution per RFC 3263, and 423 Min-Expires handling, because real carriers are not textbooks.

The server transaction layer absorbs duplicate requests and retransmits final responses, so a carrier retransmit storm never becomes a second call.

Every call closes with its duration, its billable seconds and its clearing cause, and writes a cost row against the rates you configured.

Multi-tenant from the first migration. Every table is keyed by tenant and every API call is checked against the caller's tenant scope, rather than tenancy being bolted on later as a domain prefix.

Pushing the tenant check down into PostgreSQL itself, so the database refuses a cross-tenant read even if application code asks for one. The migrations are written and adoption has not started.

Per-tenant and global concurrency ceilings. A tenant at its ceiling gets a polite busy instead of everyone's audio getting worse.

Routing rules, carrier selection and least cost routing are configuration you change from the control plane. There are no rates and no routes compiled into the build.

Direct DID lookup first, then pattern-matched inbound routes, then extension fan-out, so a number lands where you said it should.

Trunk and routing configuration rebuilds from the database without restarting the switch.

Provisioning, call records, billing data and event fan-out over REST, with webhook delivery that verifies its signature and never treats an empty secret as valid.

A WebRTC leg with server-side ICE, relay gathering and ICE restart, and Opus transcoded to whatever the SIP side speaks. The transports it rides are live; the shipped client is programme.

RFC 8599 push so a closed or backgrounded app still rings, and every device on one account rings together.

A scriptable dialplan with variable substitution and a dynamic module system, so an integrator can extend the switch without touching our code.

A SIGTRAN and SS7 stack (SCTP, M3UA, SCCP, TCAP and MAP) is written and tested against mocks. It has no caller in the platform yet, so the whole carrier tier is programme.

A REFER from the handset or from the control plane moves the call, and the switch re-targets the leg itself rather than leaving the phones to argue about it.

Consulting the colleague first, then joining the two parties. Today the Replaces dialog on an incoming REFER is parsed but not used to bridge the consultation call, so it behaves as a blind transfer with an extra hold step.

Parking a call on an orbit and picking it back up from another phone. Park and retrieve work over the feature code, but a forgotten call is torn down at expiry instead of ringing back, so we are not selling it yet.

Dialling a colleague's ringing extension answers their call at your own phone.

Answering anyone who is ringing in your pickup group. The routing is there and nothing can populate a group yet, so it never matches.

The media bridge pauses instead of tearing down, so resuming a held call does not drop or re-negotiate audio.

Queues with 4 distribution strategies, so a support line and a dealing desk can be routed on different rules.

Menu routing on DTMF with database-driven destinations. Prompts are recorded audio; there is no text to speech.

Deposit and dial-in retrieval on a feature code.

Unconditional forwarding, and do not disturb, set from the portal rather than a handset menu, with a hop limit so a forwarding loop is refused instead of ringing forever.

Forwarding only when the extension is busy or nobody picks up. The check runs on every extension call, and nothing can fill the rule table yet, so it never fires.

Held callers hear your audio, not silence they mistake for a dropped call.

Desk phones subscribe to dialog-info and are notified on every ringing, answered, held and idle change, so nobody transfers a caller into a busy line.

Up to 5 simultaneous registrations on one account, so a desk phone and a softphone share the same extension.

A mixer inside the engine, which is the base the meeting and webinar programme stands on.

Ringing a whole team on a strategy, loaded from the database so a group changes without touching the switch.

An agent marks themselves on a break and the distributor stops offering them queued calls. The switch refreshes agent status on a short cycle, so a pause takes effect within seconds rather than on the instant.

The mixer cancels echo on every conference leg, feeding each participant's own outbound mix back as the reference, and it is on by default rather than a switch somebody has to find.

Knowing who is talking and showing it. The detector now publishes a conference event, but the only thing listening discards it, so there is still nothing on screen and nothing changes in the mix.

PIN entry, moderator controls, lock and video.

A live view of every call with listen, whisper and barge, plus fleet health for devices, trunk channels and recording storage.

The softswitch on this page, under the same identity as everything else.

Hosted business email and webmail on your own domain, with calendar and contacts beside it.

Contacts, consent and history shared by every channel in the platform.

One landing surface carrying the agenda, inbox highlights, tasks, calls, chat and compliance state for the working day.

In-house messaging with retention and deal-reference tagging, and presence that follows the call state.

Work assigned and announced inside the same portal, with completion rolled up.

Recorded meetings on a media server inside your tenant, with PSTN dial-in bridged by the voice engine.

Circular distribution with per-employee task fan-out, completion roll-up and evidence export.

Registration, one-to-many audio and video, moderated question and answer, polls and an attendance report.

Course catalogue, quizzes with a pass mark, and certificates carrying expiry and recertification.

One recording, retention, legal hold and audit surface spanning every channel rather than one per product.

The corporate line on the phone, so the work number rings without the personal SIM ever entering the call path.
