Chapter 3 Initializing Cisco Unified IP Phones
Configuring the SIP Parameters Manually
Step 6
Highlight and configure each of the following parameters:
•
IP Address—IP address of the phone.
•
Subnet Mask—IP subnet mask used by the phone.
•
TFTP Server—IP address of the TFTP server from which the phone downloads its configuration
files and firmware images.
•
Default routers 1 through 5—IP address of the default gateway used by the phone. Default routers
2 through 5 are the IP addresses of the gateways that the phone attempts to use as an alternate
gateway if the primary gateway is not available.
•
Domain Name—Name of the DNS domain in which the phone resides.
•
DNS servers 1 through 5—IP address of the DNS server used by the phone to resolve names to IP
addresses. The phone attempts to use DNS servers 2 through 5 if DNS server 1 is unavailable.
Step 7
Press the
Save
softkey.
The phone programs the new information into flash memory and resets.
Setting and Restoring Phone-Specific Parameters
Phone users can modify the phone-specific configuration settings using the phone menus. If a
phone-specific configuration file exists, the phone uses locally configured parameters until the next
reboot. If a phone-specific configuration file does not exist, you must configure the phone locally with
parameters specific to that phone.
•
To configure the preferred codec and out-of-band DTMF parameters, press
Change
until the option
appears, then press
Save
.
•
If your system has been set up to have the phones retrieve the configuration file from a TFTP server,
you must use the server’s configuration file to change the parameter value to a null value (“ ”) or to
“UNPROVISIONED.” The phone uses the setting for that variable that it has stored in flash memory.
•
If the telnet_level parameter is set to allow privileged commands to be executed, the entire SIP
configuration can be erased. Use the
erase_protflash
command so that the phone can retrieve its
configuration files.
Prerequisites
•
Define the line parameters (those identified as line
x
) on the phone. If you configure a line to use an
e-mail address, that line can be called only by using an e-mail address. Similarly, if you configure a
line to use a number, that line can be called only by using the number.
To set phone-specific parameters, follow these steps:
