SIP & Network
The network element that sits at the edge of a voice network to control signaling and media, enforce security policy, and normalize SIP between networks.
An SBC handles topology hiding, NAT traversal, transcoding, registration throttling, and access control. It is also the natural insertion point for authentication and fraud policy, because every call crosses it.
Most STIR/SHAKEN deployments integrate the authentication and verification services directly with the SBC so signing happens inline with call setup.
If a fraud decision cannot be enforced at the SBC in real time, it is a report rather than a control.
The originating-side service that decides an attestation level, builds the PASSporT, signs it, and inserts the Identity header into the outbound SIP INVITE.
The signaling protocol used to set up, modify, and tear down voice and video calls over IP networks.
A virtual connection that carries voice calls over IP between a business phone system and a voice provider, replacing physical phone lines.
The software-based call control platform that routes calls, applies rating and policy, and connects customers to upstream carriers.
SipShield scores live SIP traffic with patented AI so the controls behind this term run automatically — and leave the audit trail regulators expect.
