VoIP capacity planning: size voice for busy periods and failure
Plan VoIP capacity around concurrent calls, codec overhead, access links, Wi-Fi airtime, QoS and degraded-state demand.
Topics
Voice quality
VoIP call-quality checklist
A practical pre-launch and incident checklist for checking delay, jitter, packet loss, codecs, RTP, Wi-Fi, and user experience.
VoIP codec comparison
Compare G.711, G.722, Opus, G.729, iLBC, and AMR by bandwidth, interoperability, speech quality, and deployment context.
Voice quality and testing hub
Diagnose and improve voice quality using codec selection, QoS, packet measurement, Wi-Fi testing, RTP evidence, and repeatable call plans.
Voice quality testing: a practical test plan
Test VoIP quality with repeatable calls, realistic paths, controlled impairments, user scenarios, and measurable acceptance criteria.
Voice codec guide
Compare common voice codecs by payload rate, speech bandwidth, interoperability, delay, and practical deployment considerations.
VoIP QoS: latency, jitter, packet loss, and capacity
Learn how delay, jitter, packet loss, and congestion affect voice calls, and use a practical checklist to improve call quality.
