CONFIGURING DHCP ON SHORETEL IP PHONES

Configuring DHCP for ShoreTel IP Phones
The ShoreTel server provides the IP phones with the latest application software and the
configuration information that enables the IP phone to be automatically added to the
ShoreTel5 system. The ShoreTel server’s address must be provided to the phone as a
vendor-specific option. ShorePhone-IP100 telephones are preconfigured to look for the
ShoreTel server’s address to be specified as Vendor Specific DHCP option 155.
ShorePhone-IP210/530/560 telephones are preconfigured to look for the ShoreTel
server’s address to be specified as Vendor Specific DHCP option 156. If these options
are not available, the ShoreTel IP phones will use option 66.

To set up DHCP option 155 for ShorePhone-IP100 telephones:
Step 1 Open DHCP Manager on your Microsoft DHCP server.
Step 2 Right-click the DHCP server, and select Set pre-defined options.
Step 3 Click Add.
Step 4 Set Name to IP Phone Boot Server.
Step 5 Set Data Type to IP address.
Step 6 Set Code to 155 and add a description, if desired.
Step 7 Navigate to the scope options and add option 155.
Step 8 Set the value of option 155 to the IP address of your ShoreWare server.
Step 9 Connect the Ethernet cable to the data jack on the back of the IP phone.
The phone downloads the latest bootROM and firmware from the
ShoreTel server and in the process, reboots several times. When the
phone displays the date and time, the upgrade process is complete.

To set up DHCP option 156 for ShorePhone-IP210/530/560 telephones:
Step 1 Open DHCP Manager on your Microsoft DHCP server.
Step 2 Right-click the DHCP server, and select Set pre-defined options.
NOTE If your organization is separated into separate subnets, make sure to select the
proper subnet. For example, if you have a global organization and would like to
configure the DHCP server to deliver the Spanish tones and cadences only to the
IP phones in your office in Spain, you should make sure to select that particular
subnet of users. If you do not specify the subnet, then all phones that boot from
this DHCP server will receive Spanish tones and cadences.
Step 3 Click Add.
Step 4 Set Name to IP Phone Boot Server.
Step 5 Set Data Type to String.
Step 6 Set Code to 156 and add a description, if desired.

where ip_address equals the IP address of your ShoreWare
Headquarters server.
