SSIPMASTER

Features

Everything you need to point a dialer at the PSTN and pay only for what you use.

Per-second billing

No rounding up to the minute. Calls are rated to the second against your prepaid balance, with per-destination increments.

Verified caller ID

Prove control of a number with an automated verification call, then present it on outbound calls for A-attestation and better answer rates.

Bring any dialer

Standard SIP credentials register with MicroSIP, Zoiper, or any softphone. Manual routes — you control the client.

Hard balance cutoff

The switch computes a max call duration from your balance and stops the call before you can go negative.

Crypto funding

Top up with Bitcoin or stablecoins. Instant confirmation, irreversible, no chargebacks or card declines.

Call records + CSV

Every completed call writes a CDR. Filter by destination, status, and date, then export to CSV.

Rotatable credentials

Regenerate your SIP password any time. Usernames are fixed and never editable — no hijacking.

Carrier-grade routing

Calls bridge through a hardened softswitch to tier-1 termination. TLS signaling and SRTP media supported.
