Hardware implementation of Voice-over-IP playback with support for comfort noise insertion

摘要

Methods and apparatus are presented for scheduling playback for voice data sample packet payloads conveyed over best-effort packet-switched infrastructure. The hardware implementation presented provides support for concurrent and independent comfort noise insertion and for dynamic clock adjustment for telephone sessions provisioned concurrently without making recourse to signaling. The apparatus and methods support high density solutions scaleing up to large numbers of concurrently provisioned telephone sessions.
