Aastra Telecom CT9143i manual Dhcp Option 12 Hostname for the Configuration Server

SIP IP Phone Models 9143i, 9480i, 9480i CT and 5i Series Phones Release Note 2.3

New Features in Release 2.3

DHCP Option 12 Hostname for the Configuration Server

Release 2.3 includes a new DHCP Option 12 that the phone automatically sends 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.

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.

An Administrator can change the “Hostname” for the DHCP Option 12 via the configuration files, the IP Phone UI, and the Aastra Web UI.
