Description
The IP Phones support Link Layer Discovery Protocol
for Media Endpoint Devices (LLDP-MED).
In addition to DHCP options 43 and 66 already
supported on the IP Phones, Release 2.3 provides new
DHCP Options 159 and 160.
The IP Phones support DHCP Option 12 that the phone
automatically sends to the configuration server. This
option specifies the hostname (name of the client).
The IP Phones support DHCP Option 77 User Class,
that is sent in DHCP request packets from the phone to
the configuration server. This Option 77 defines specific
User Class identifiers to convey information about a
phone's software configuration or about its user's
preferences.
In Release 2.3, the IP Phones can now receive
messages from multiple DHCP servers.
Some vendors can have specific methods to encrypt
files on their configuration servers. For each phone, the
configuration server can generate a random hex string
(encryption key) that is used to encrypt the phone's
MAC-specific configuration file.
The HTTPS client on the IP Phones now support the
validation of HTTPS certificates.
The IP Phones now allow a WAV file to be played or
stopped via XML Execute commands.
The IP Phones allow for RTP recording and
simultaneous playing of an audio file via XML Execute
commands.
