SBC and IMS capacity utility for quantifying the MOS degradation, added latency, and computing cost of audio codec transcoding chains in real-time telecom media paths.
Transcoding impact calculators estimate latency and quality loss across multi-stage VoIP codec conversions so SBC designs minimize unnecessary DSP hops.
The analyzer calculates the cumulative MOS degradation from each transcoding step using ITU-T codec quality models, adds conversion latency, and estimates SBC DSP or vCPU load per concurrent session.
Built on 3GPP Technical Specifications, ensuring accuracy for production deployments and security audits.
Calculations specifically designed to identify protocol vulnerabilities and signaling misconfigurations.
Avoidable transcoding is a core SBC/IMS design principle. This tool supports codec negotiation policy design and media gateway capacity planning in IMS, SIP interconnects, and WebRTC gateways.

Two tandem transcodes can add tens of milliseconds and a noticeable MOS hit versus a single common codec end-to-end.
Exact MOS deltas depend on implementations; use as relative guidance.
Each encode/decode stage adds delay and distortion. Cascaded transcoding (e.g., G.729↔G.711↔Opus) compounds MOS loss.
When endpoints or trunks lack a common codec. Prefer codec alignment on SIP trunks to avoid SBC transcode farms.
Yes—DSP/session resources and added latency budgets. Size SBCs for transcode concurrency separately from signaling sessions.
Calculate required SIP trunks based on traffic parameters and quality requirements.
Dimension P-CSCF, S-CSCF, and I-CSCF nodes for VoLTE/VoNR networks based on BHCA and concurrent sessions.
