How it works
Live in three steps, not three weeks
Step 1: Open an account
Sign up in two minutes. Your first SIP line is created instantly and the credentials are shown once.
Step 2: Fund with USDT or Bitcoin
Send the exact amount from the Wallet. The balance appears automatically once the network confirms.
Step 3: Connect and dial
Point your dialer or cloud PBX at our SIP server, buy numbers if you need them and start calling.

Customer stories
Teams that switched and stayed
We moved a 40-seat outbound team over a weekend. Answer rates held steady and topping up with USDT takes less time than writing an invoice request.
Being able to buy numbers for a new market and point them at our PBX in a couple of clicks is exactly what our support team needed.
Clear per-minute pricing, a portal that shows every call and a human who answers the chat. That combination is rarer than it should be.
