Yealink IP phones support obtaining the provisioning server address from DHCP options.
You can configure the phone to obtain a provisioning server address from a custom
DHCP option, or the phone will automatically detect the Option 66 or Option 43. The
Option 66 is used to identify the TFTP server.
To obtain a provisioning server by a custom DHCP option, make sure that the DHCP
option is set properly.
To configure the DHCP option via web user interface:
1. Click on Upgrade ->Advanced.
2. Select Enabled from the pull-down list of DHCP Active.
3. Enter the value in the Custom Option (128~254) field.
4. Select the desired type from the pull-down list of Custom Option Type.
5. Click Confirm to accept the change.
A valid Custom Option is from 128 to 254. The Custom Option Type must be in accordance
with the one defined in the DHCP server.
Yealink IP phones support obtaining a provisioning server address from the phone flash.
To obtain a provisioning server address by reading the phone flash, make sure the
configuration is set properly.
