New Features in 1.4.141-001024-00, Rev 09, Release 1.4.1 39SIP IP Phone Models 480i, 480i CT, 9112i, 9133i Release NotesAuto-discovery Using mDNSRelease 1.4.1 introduces a process that allows the phones to auto-discover allservers on a network using mDNS. When the IP phone discovers a TFTP server, itis automatically configured by that TFTP server.An unconfigured phone (phone right out of the box) added to a network, attemptsto auto-discover a configuration server on the network without any end-userintervention. When it receives DHCP option 66 (TFTP server), it automaticallygets configured by the TFTP server.An already configured phone (either previously configured by auto-discovery ormanually configured) added to a network, uses its predefined configuration toboot up.Notes:1. Configuration parameters received via DHCP do not constituteconfiguration information, with the exception of a TFTP server.Therefore, you can plug a phone into a DHCP environment, still use theauto-discovery process, and still allow the use of the TFTP serverparameter to set the configuration server.2. DHCP option 66 (TFTP server details) overrides the mDNS phase ofthe auto-discovery. Therefore, the DHCP option takes priority and theremaining process of auto-discovery continues.3. As the phone performs auto-discovery, all servers in the network(including the TFTP server), display in the phone window. However, onlythe server configured for TFTP automatically configures the phone.
