Configuring and Verifying Network Settings on the Cisco IP Phone

---

Because the Cisco IP Phone is a network device, it includes many configurable network settings. You must configure many of these options before the phone is accessible and functional for your users.

The following sections provide details about configuring and verifying these network settings:

•Accessing the Network Configuration Settings

•Verifying Network Settings

•Modifying DHCP Settings

•Configuring IP Settings

•Configuring VLAN Settings

•Configuring TFTP Options

•Configuring Ports

•Obtaining Status and Version Information

•Modifying Global Settings

Accessing the Network Configuration Settings

By default, the network configuration options are locked to prevent users from making changes that could impact their network connectivity. You must unlock the network configuration options before you can configure them.

The unlocked padlock icon, shown below, appears in the margins of this chapter to indicate procedures that require you to unlock settings before modifying them.

The padlock icon also appears in the Network Configuration area of the Cisco IP Phone LCD screen to indicate that settings are unlocked and accessible for modification.

When settings are inaccessible, you can see an image of a locked padlock on the LCD screen. After you make the necessary changes to the network configuration settings, be sure to lock the settings again to prevent users from modifying them.

Follow these steps to view the padlock icon and to modify network settings:

Configuring IP Settings

Use these guidelines when manually configuring the IP settings:

•You can use 0.0.0.0 for the subnet mask only if the default gateway is also 0.0.0.0.

•Ensure TFTP server has an IP address.

•Ensure the default gateway IP address is on the same subnet as the host IP address.

Assigning an IP Address

The IP address is the unique logical address identifying each host computer, or node, on a TCP/IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 separated by periods.

Each IP address has two parts: the network ID and the host ID. The network ID identifies all hosts that are on the same physical network. The host ID identifies a specific host on a network.

Configuring Ports

The PC and switch (SW) port configuration settings determine the speed and duplex of the PC and network ports, respectively.

If you change the port configuration setting value for either the PC port or the SW port, you must change the other to match or configure both to auto-negotiate.

If the phone is connected to a switch, you must configure the switch's port to the same speed/duplex as the phone, or configure both to auto-negotiate.

The values for both are: A (auto-negotiate), 10H (10BaseT/Half Duplex), 10F (10BaseT/Full Duplex), 100H (100BaseT/Half Duplex), or 100F (100BaseT/Full Duplex). This setting is not case sensitive.

Displaying Statistics for Current Call

If you experience problems during an active call, collect information during the call.

Cisco IP Phone 7960/7940

During the call, press the i button twice rapidly. The following information displays:

•RxType—Type of voice stream received (RTP streaming audio) (G.729, G.711 u-law, or G.711 A-law).

•RxSize—Size of voice packets (in milliseconds) in the receiving voice stream (RTP streaming audio).

•RxCnt—Number of RTP voice packets received since voice stream was opened (which is not necessarily identical to those received since call began because calls can be put on hold).

•TxType—Type of voice stream transmitted (RTP streaming audio) (G.729, G.711 u-law, or G.711 A-law).

•TxSize—Size of voice packets in the transmitting voice stream (in milliseconds).

•TxCnt—Number of RTP voice packets transmitted since voice stream was opened (which is not necessarily identical to those received since call began because calls can be put on hold).

•Avg Jtr—Estimated average RTP packet jitter (dynamic delay a packet encounters when going through the network) observed since the receiving voice stream was opened.

•Max Jtr—Maximum jitter observed since the receiving voice stream was opened.

•RxDisc—Number of RTP packets in the receiving voice stream that have been discarded (bad packets, too late, and so on).

•RxLost—Missing RTP packets (lost in transit).

Viewing Status Messages
