Infrastructure

Carrier-grade plumbing, without the plumbing.

Behind your dashboard sits a real telephony stack: SIP registration, multi-carrier routing with failover, and per-minute rating. You click, we provision.

✓ Instant SIP provisioning: credentials generated per workspace, revocable anytime.

✓ Least-cost routing: every call takes the best available carrier route.

✓ Isolated workspaces: tenant separation enforced in the database itself.

For operators & teams

From one line to a whole floor.

Start with a single SIP account on a day licence; scale to multiple numbers, users and concurrent calls on monthly plans. Same dashboard, same wallet, no re-setup.

✓ Daily, weekly & monthly licences: pay for the period you actually need.

✓ Works with any softphone: Zoiper, Linphone, desk phones, PBXs.

✓ Roles & members: owner, admin, billing and support roles per workspace.

Billing you can audit

Every cent has a paper trail.

Your balance is not just a number in a box: it is the sum of a full transaction history. Deposits, licence fees and per-minute charges are each a signed, traceable entry.

✓ Prepaid by design: calls reserve credit before they connect, debt is impossible.

✓ Crypto deposits: confirmed on-chain, credited exactly once.

✓ Full transaction history: balance after every single movement.

Security & compliance

Built like infrastructure, not a demo.

Tenant isolation is enforced in the database itself with row-level security. Every financial movement lives in an append-only ledger. Caller ID is locked to numbers you verifiably own — spoofing is impossible by construction, matching STIR/SHAKEN and Swiss OTS Art. 26a rules.

✓ Row-level security on every tenant table

✓ Complete financial history, every cent traceable

✓ MFA, Argon2id hashing, rotating sessions

✓ Non-custodial crypto processing, keys never touch us

✓ Anti-fraud spend caps and destination controls

FAQ

Common questions

What is a DID?

A DID is a real phone number rented to your workspace. It receives inbound calls and serves as your verified outbound caller ID.

Can I set any caller ID?

No, and that is by design. Only numbers you own or have verified through the platform can be presented, in line with telecom anti-spoofing regulation (STIR/SHAKEN and the Swiss OTS Art. 26a rules).

How does billing work?

Two things: a licence (daily, weekly or monthly) that grants access, and a prepaid wallet that pays for calls per minute. Every movement is recorded in an auditable ledger.

What happens when my balance runs out?

Calls are admission-checked against your available balance and capped by reservation. When credit is exhausted the call ends. You can never go into debt.

Which countries do you focus on?

Belgium and Switzerland first, with international termination. Local numbers follow each country’s verification rules (proof of address / KYC), which we guide you through.
