Here are some books or authors I have found useful in better understanding
the complex math behind this subject |
Some useful documents are:
VoIP References |
 |
A Cisco document on general Traffic Engineering, with a method of calculating VOIP. It is a good starting point, but does not cover Layer-2, Control, or VAD effects. Also, Frame Relay overhead omits the ‘Flag’ byte required for each frame.
Read It. |
 |
A white paper on ATM–AAL2, explaining clearly how the multiplexed voice channels are assembled into frames of ATM cells. The VAD discussion is superficial; applying an optimistic VAD multiplier to the final answer, instead of including the effect in the number of CELLS per FRAME.
Read It. |
 |
A discussion similar to the one above, that also helps explain ATM-AAL2.
Read It. |

Voice
over IP Fundamentals
By: Jonathan Davidson, et al.
Covered topics: The Public
Switched Telephone Network (PSTN), signaling specifications (including
Bell System, ISDN, and Signaling System 7), the basics of Internet
Protocol (IP), modulation and compression of voice, Quality of Service (QoS),
H.323, Session Initiation Protocol (SIP), and gateway protocols. Business
considerations of Internet telephony are also addressed. |

Carrier
Grade Voice over IP
By: Daniel Collins
Daniel Collins has written a terrific reference for anyone
interested in understanding Voice Over IP. From the very start of the book,
it is clear that Collins has the ability to address key areas of interest
for technical readers, planners, and executives. |

Configuring
Cisco Voice over IP
By: Syngress Media, et al.
This is the book that I have been looking for. The first
chapter of the book provides a good high level business justification for
VoIP in the enterprise and then quickly launches into a background on the
technology. Intricate detail on the particulars of H.323, SIP and MGCP.
The following configuration chapters also clearly presented the concepts
using examples and sample config files. Highly recommended for anyone
considering a VoIP deployment. VoIP will be included on the CCIE as well. |
