–Configure Ethernet port mode and speed

–Register with or unregister from a proxy server

–Specify a TFTP boot directory

–Configure a label for phone identification display purposes

–Configure a name for caller identification purposes for each active line on a phone

•In-band dual-tone multifrequency (DTMF) support for touch-tone dialing

•Out-of-band DTMF signaling for codecs that do not transport the DTMF signaling correctly (for example, G.729 or G.729A)

•Local or remote (using the SIP 183 Ringing message) call progress tone

•AVT payload type negotiation

•Network startup via DHCP and Trivial File Transfer Protocol (TFTP)

•Dial plan support that enables automatic dialing and automatic generation of a secondary dial tone

•Current date and time support via Simple Network Time Protocol (SNTP) and time zone and daylight savings time support

•Call redirection information support via the CC-Diversion header

•Third-party call control via delayed media negotiation. A delayed media negotiation is one where the Session Description Protocol (SDP) information is not completely advertised in the initial call setup.

•Support for endpoints specified as Fully Qualified Domain Names (FQDNs) in the SDP

•Local directory configuration (save and recall) and automatic dial completion—Each time a call is successfully made or received, the number is stored in a local directory that is maintained on the phone. The maximum number of entries is 32. Entries are aged-out based on their usage and age. The oldest entry called the least number of times is overwritten first. This feature cannot be programmed by the user, however, up to 20 entries can be “locked” (via the Locked soft key) so that they will never be deleted.
