The following shows an example of a local contact file used for SIP-T23 (P/G) IP phones:
<root_group>
<group display_name="All Contacts" ring=""/>
<group display_name="Family" ring="Resource:Ring1.wav"/>
<group display_name="Friend" ring="Auto"/>
</root_group>
<root_contact>
<contact display_name="Mary" office_number="123" mobile_number="456"
other_number="2201" line="0" ring="Auto" group_id_name="Family"/>
<contact display_name="Damy" office_number="124" mobile_number="789"
other_number="2202" line="1" ring="Resource:Ring2.wav" group_id_name=""/>
<contact display_name="Jack" office_number="125" mobile_number="234"
other_number="2203" line="2" ring="Custom:lin.wav" group_id_name="Family"/>
<contact display_name="Ada" office_number="8800" mobile_number="1234"
other_number="0000" line="0" ring="" group_id_name=""/>
</root_contact>

## Configure the custom local contact file ##

# Specify the access URL of the custom local contact file.
local_contact.data.url =
For example, enter “tftp://192.168.1.100/contact.xml” in the “local_contact.data.url =”
field. During the auto provisioning process, the IP phone connects to the provisioning
server “192.168.1.100”, and downloads the contact file “contact.xml”.
For more information on these parameters, refer to Description of Configuration
Parameters in CFG Files on page 81.
You can create replace rules directly in configuration files, or create multiple replace
rules using the supplied replace rule template file. The existing replace rules on the IP
phones will be overwritten by the downloaded replace rules.
When editing the replace rule template file, learn the following:
 <DialRule> indicates the start of the template file and </DialRule> indicates the
end of the template file.
 Create replace rules between <DialRule> and </DialRule>.
 When specifying the desired line(s) to apply the replace rule, valid values are 0
