Quality of Service & Erlang Precision
Voice services demand strict QoS. Whether you are dimensioning SIP trunks for a global carrier or calculating call center agent requirements using Erlang C, our traffic engineering tools ensure you meet grade-of-service targets with minimal waste.
Voice capacity starts with the right Erlang model: Erlang B for trunks that clear busy calls, Erlang C for queued contact-center agents. Then size SIP channels, codec bandwidth (G.711/G.729/Opus), jitter/MOS, transcoding impact, and IMS CSCF nodes for VoLTE/VoNR cores.
Dimension P-CSCF, S-CSCF, and I-CSCF nodes for VoLTE/VoNR networks based on BHCA and concurrent sessions.
Calculate required SIP trunks based on traffic parameters and quality requirements.
Classic tool for determining circuit requirements with zero queuing.
Estimate Opus codec nominal bitrates and total IP bandwidth including RTP/UDP/IP overhead.
Analyze voice quality (MOS) impact based on network jitter and packet loss.
Estimate technical quality degradation and processing latency for multi-stage VoIP transcoding.
Queue-based capacity planning for call center staffing.
Visual calculator for mapping PCM trunk timeslots (24 or 32 channels) to allocate SS7 signaling and voice bearer channels.
Calculate IP bandwidth required for G.711 and G.729 VoIP codecs, including RTP/UDP/IP overhead.
