Your full rate deck is visible in the dashboard before you make a single call — the same deck that bills your traffic. How billing works is on the rates page.

Prepaid isn't a limitation. It's the point.

Most carriers bill you at the end of the month and make you guess what the invoice will say. We do it the other way around: you load a balance, and every call rates against it in real time — you can watch it happen in your dashboard, call by call.

  • Hard cutoff at zero. The switch computes a max duration from your balance before the call bridges. A compromised extension can't run up a five-figure bill overnight.
  • 6-second increments. Short calls bill as short calls — no rounding everything up to the next full minute.
  • Every call gets a CDR. Duration, rate, cost, hangup cause. Filter it in the dashboard or export it as CSV.
  • Top up how you like. Fund your wallet online in a couple of clicks; the balance is live immediately.

From signup to your first call

Step 1

Load your balance

Create an account and top up. No contracts, no minimums, no monthly fee — the balance is yours until you use it.

Step 2

Verify your caller ID

Prove you control the number you want to present with an automated verification call. Unverified traffic never leaves our switch.

Step 3

Point your dialer

Drop the SIP credentials into VICIdial, FreePBX, MicroSIP — anything that speaks SIP — and dial.

A small network we actually run

We're not a reseller portal wrapped around someone else's switch. Calls bridge through our own FreeSWITCH-based B2BUA with encrypted signaling and media support, and the same engineers who built the platform answer the support tickets.

When something breaks — it happens — you talk to the person who can fix it, not a ticket queue.
