SIP Trunking: SIP trunking services provide public switched telephone network (PSTN) connectivity for on-premises as well as hosted and cloud unified communications platforms that support “bring your own carrier” (BYOC) services. Providers typically offer a mix of connectivity options, pricing, and support for existing enterprise-owned session border controllers (SBCs). They may also offer SBC functionally, hosted by the provider, as part of their SIP trunking offering. In addition, SIP trunking providers may offer APIs to support number provisioning and management. Additional options include integrated third-party tools for administration management, security capabilities such as toll-fraud detection and protection against SIP-based attacks, encryption, and performance management to guarantee voice quality.
