16. H.323 The first VoIP

20. SIP Session Initation Protocol – NEXT Generation of H.323

23. MGCP Media Gateway Control Protocol – First true client/server VoIP signaling protocol “Call agent” – Not as widely supported as H.323 or SIP

24. SCCP Skinny Client Control Protocol – Only Cisco proprietary protocol in use today – Its function is to provide signaling between the Cisco Unified Communication Manager and the Cisco IP phones

75. QoS (Quality of Service) Bandwidth Delay – Fixed delay – Variable delay – Jitter (delay variations) – Packet loss End-to-end delay budget: <150 ms Jitter: 30 <30 ms Packet loss: <1%

76. Cisco AutoQoS Advantages over manual QoS configuration Reduces time of deployment Provides configuration consistency Reduces deployment cost Still allows for manual tuning
