Chapter 55 Configuring a VoIP Network

Understanding How a VoIP Network Works

The IP phone is Dynamic Host Configuration Protocol (DHCP) capable. Optionally, you can program the IP phone with a static IP address.

The IP phone can be powered by the following sources:

•External power source—Optional transformer and power cord for connecting to a standard wall receptacle.

•Ethernet switching modules with the voice daughter card installed—Provides the inline power to the IP phone.

•WS-PWR-PNL (inline-power patch panel)—Provides the inline power to the IP phone. The inline patch panel allows the IP phone to connect to existing Catalyst 4500 series, 5000 family, and 6500 series 10/100BASE-TX switching modules.

•WS-PWR-PNL (inline-power patch panel)—Provides the inline power to the IP phone. The inline patch panel allows the IP phone to connect to existing Catalyst 4500 series, 5000 family, and 6500 series 10/100BASE-TX switching modules.

•WS-X6148-RJ-45 10/100 switching module with either the WS-F6K-VPWR inline-power field-upgrade module or the WS-F6K-FE48-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

•WS-X6148-RJ-21 10/100 switching module with either the WS-F6K-VPWR inline-power field-upgrade module or the WS-F6K-FE48-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

•WS-X6148X2-RJ-45 10/100 switching module with the WS-F6K-FE96-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

•WS-X6148X2-RJ-21 10/100 switching module with the WS-F6K-FE96-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

•WS-6548-GE-TX Gigabit Ethernet switching module with either the WS-F6K-VPWR-GE inline-power field-upgrade module or the WS-F6K-GE48-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

•WS-6148-GE-TX Gigabit Ethernet switching module with either the WS-F6K-VPWR-GE inline-power field-upgrade module or the WS-F6K-GE48-AF inline-power field-upgrade module—Provides the inline power to the IP phone.

Figure 55-2shows how to connect the Cisco IP Phone 7960 and PCs to the Catalyst 6500 series switch.
