Where the calls go
Questions
- How is this different from a "free" or "unlimited" SIP trunk?
- There is no trunk fee and no per-channel fee; you pay for minutes at $0.010 outbound and $0.009 inbound, plus $1.50 a month per number. Providers who advertise unlimited plans size and cap channels; we do not.
- How fast can I place a test call?
- Self-service signup provisions the trunk immediately: sign up, point your PBX at the trunk host, place a call. Or request a test trunk below and an engineer sets it up with you the same business day.
- Is it secure?
- TLS signaling and SRTP media on your trunk when you use 5061, TLS and SRTP from us to our carriers, and every call STIR/SHAKEN-signed at A attestation, outbound and inbound.
- What if I already have numbers?
- Port them in at $5.00 per number, free for 100 or more. Local ports usually complete in 7–14 business days and toll-free in 5–10; your current carrier keeps carrying each number until its port date.
