Configuring Physical Voice Port Characteristics:
According to the OSI Model, the Physical layer is
where it all begins. Similarly, some basic voice-port
configuration items can prove essential to setting up
your connections to the legacy voice environment.
This section breaks down the key commands used in
analog and digital voice connections.

Understanding and Configuring Dial-Peers:
If
there were one most important topic for all things re-
lated to voice in CME, this would be it. Dial-peers de-
fine the “routing table” for your voice calls. This
section discusses the configuration of both POTS
and VoIP dial-peers through many practical examples.
■
Understanding Router Call Processing and
Digit Manipulation:
Even the simplest of all VoIP
environments need to modify dialed digits or caller
ID information for incoming and outgoing calls. This
section breaks down the core digit-manipulation
commands and explores the flow of a typical CME-
handled call.
■
Understanding and Implementing CME Class of
Restriction (COR):
Just like you can use access lists
to secure the data plane of your router, COR lists se-
cure access to dialed numbers in your VoIP environ-
ment. This section discusses the concepts and
configuration of COR lists.
■
Quality of Service:
Regardless of how beautiful
and expansive your VoIP network, a voice network
missing QoS is like confidential data lacking secu-
rity—it won't last long. This section quickly
overviews QoS and the configuration of AutoQoS
on switches and routers.
