  • Abstract
    Adaptive playout algorithms provide a popular way to calculate voice-over-IP (VoIP) packets´ playout delay - the difference between the playout time at the receiver and the packet-generation time at the sender. The authors´ proposed per-call adaptive algorithm uses network delays received from the VoIP gatekeeper to switch between fixed and call-adaptive playout. Their approach also reduces loss rates while increasing playout delay only slightly.
