VoIP capacity planning utility for sizing SIP trunks based on concurrent call model, codec selection, and quality profile — applicable to enterprise PBX, SBC, and carrier VoIP interconnects.
The sizer applies Erlang B traffic engineering to convert offered load (Erlangs) to channel count at a target blocking threshold, then computes aggregate RTP/UDP/IP bandwidth.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Essential for SBC, carrier IP PBX, and ITSP interconnect planning. Accurate SIP trunk sizing prevents call blocking during peak hours and avoids overprovisioning costs.
