IP Phone Administrator Guide
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.
FTP ftp://user:password@ftpserver option tftp-server-name “ftp://192.168.1.45”;
option tftp-server-name “ftp://ftpsvr.example.com”;
(for anonymous user)
option tftp-server-name “ftp://userID:password@
ftpsvr.example.com”;
TFTP tftp://tftpserver option tftp-server-name “192.168.1.45”;
option tftp-server-name “tftpsvr.example.com”;
option tftp-server-name “tftp://tftpsvr.example.com”;
Notes:
1. The hostname of [<model><MAC address>] automatically
populates the field on initial startup of the phone. For example, for a 53i,
the “Hostname” field is automatically populated as “53i00085D164435”,
where the model number is “53i” 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.
