Sign every call. Earn the answer.
Sign outbound calls so networks trust they come from you, and customers see a verified mark before they pick up.

An unsigned call is a stranger.
A signed call is one they know.
Signing proves a call really comes from you and your customer, so networks and handsets have a reason to trust it.
Signed in the switch, checked on arrival.
Signing runs inside our switches, with no extra hops between your trunk and the network.
Signed at the level the call has earned.
Each outbound call is signed at the right level, based on who owns the number and who the customer is. Prove ownership first, and calls earn the strongest signature.

Spoofed calls stop at the door.
Signatures are checked on every call arriving on your network, so calls pretending to come from a verified brand are blocked or labelled. Calls that leave unsigned are found and fixed.
