*Important: A VoIP PBX processing real-time audio in 5 ms frames requires strict performance guarantees. Any delay beyond this threshold results in audio quality degradation, jitter, packet loss and cancelled fax transmissions, etc. Unlike standard workloads, where brief performance dips are acceptable and expected, VoIP must maintain absolute consistency in processing.
