Customizing the Cisco SIP IP Phone Ring Types
The Cisco SIP IP phone ships with two ring types: Chirp1 and Chirp2. By default,
your ring type options will be those two choices. However, using the
RINGLIST.DAT file, you can customize the ring types that are available to the
Cisco SIP IP phone users.
Step 1
Create a pulse code modulation (PCM) file of the desired ring types and store the
PCM files in the root directory of your TFTP server. PCM files must contain no
header information and comply with the following format guidelines:
•
8000 Hz sampling rate
•
8 bits per sample
•
ulaw compression
Step 2
Using a ASCII editor, open the RINGLIST.DAT file and for each of the ring types
you are adding, specify the name as you want it to display on the Ring Type menu,
press Ta b , and then specify the filename of the ring type. For example, the format
of a pointer in your RINGLIST.DAT file should appear similar to the following:
Ring Type 1 ringer1.pcm
Step 3
After defining pointers for each of the ring types you are adding, save your
modifications and close the RINGLIST.DAT file.
Creating Dial Plans
Dial plans enable the Cisco SIP IP phone to support automatic dialing and
automatic generation of a secondary dial tone. If a single dial plan is to be used
for a system of phones, the dial plan is best specified in the default configuration
file. However, you can create multiple dial plans and specify which phones are to
use which dial plan by defining the dial_template parameter in the phone-specific
configuration file. If one phone in a system of phones needs to use a different dial
plan than the rest, you need to define the differing dial plan by specifying the
dial_template parameter in that phone’s phone-specific configuration file.
