Aastra 9000i Series Administrator's Manual page 173

Using Option 12 Hostname on the IP Phone
If you set the phone to use DHCP Option 12, the phone automatically sends this option to the
configuration server. This option specifies the hostname (name of the client). The name may or
may not be qualified with the local domain name (based on RFC 2132). See RFC 1035 for
character set restrictions.
An Administrator can change the "Hostname" for the DHCP Option 12 via the configuration
files, the IP Phone UI, and the Aastra Web UI.
Configuring DHCP Option 12 Hostname on the IP Phone
Use the following procedures to configure DHCP Option 12 Hostname on the IP Phone.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section,
Settings" on page A-13.

If you want to change the hostname, enter a hostname for your phone in the "Hostname" field, then

Notes:
1.
The hostname of [<model><MAC address>] automatically
populates the field on initial startup of the phone. For example, for a
6753i, the "Hostname" field is automatically populated as
"53i00085D164435", where the model number is "6753i" and the MAC
address is "00085D164435".
2.
If the configuration server sends the hostname back to the phone in
a DHCP Reply Packet, the hostname is ignored.
