Understanding How the Cisco IP Phone Interacts with Cisco CallManager
Cisco CallManager is an open and industry-standard call processing syst em.
Cisco CallManager software runs on a Windows 2000 server and sets up and tears
down calls between phones, integrating traditional PBX functionality with the
corporate IP network. CiscoCallManager manages the components of the IP
telephony system—the phones, access gateways, and the resources necessary for
such features as call conferencing and route planning .
For information about configuring CiscoCallManager to work with the IP
devices described in this chapter, refer to the Cisco CallManager Administration
Guide and the Cisco CallManager System Guide.
Understanding How the Cisco IP Phone Interacts with the Cisco Catalyst Family of Switches
Cisco IP Phones have an internal Ethernet switch, enabling them to switch
incoming traffic to the phone, the access port, or to the network port (see the
“Connecting to the Network” section on page 2-6 for detail s).
If a computer is connected to the access port, data packets traveling to and from
the computer, and to and from the phone, share the same physical link to the
switch and the same port on th e switch.
