ADVANCED OPERATIONAL FEATURES
DESCRIPTION
This section provides the following information about advanced features of the IP phones:
FEATURE DESCRIPTION
TR-069 Support The IP Phones support the Technical Report (TR) 069
Protocol, a Protocol that provides the communication between
Customer-Premises Equipment (CPE) (like the IP Phones)
and Auto Configuration Servers (ACS) over DSL/broadband
connections.
MAC Address/Line Number in
REGISTER Messages Allows you to enable or disable the sending of the MAC
address and line number from the IP phone to the call server,
in a REGISTER message.
SIP Message Sequence for Blind
Transfer Allows you to enable or disable the phone to use the Blind
Transfer method available in software prior to release 1.4.
Update Caller ID During a Call Allows you to enable or disable the updating of the Caller ID
information during a call.
Boot Sequence Recovery Mode Allows you to enable or disable Web recovery mode and set
the maximum boot count on the IP phone.
Auto-discovery Using mDNS
T
he IP phones automatically perform an auto-discovery of all
servers on a network using mDNS. When the IP phone
discovers a TFTP server, it is automatically configured by that
TFTP server.
Missed Call Summary Subscription Allows missed calls that have been redirected by the server,
to be incremented in the missed calls indicator on the phone it
was initially directed to.
As-Feature-Event Subscription Allows you to enable or disable a specific line on the phone
with the BroadSoft’s server-side DND, CFWD, or ACD
features.
Blacklist Duration Allows you to specifies the length of time, in seconds, that a
failed server remains on the server blacklist. The IP phone
avoids sending a SIP message to a failed server (if another
server is available) for this amount of time.
Whitelist Proxy Allows you to configure the phone to either accept or reject call
requests from a trusted proxy server.
Transport Layer Security (TLS) Allows you to enable or disable the use of Persistent
Transport Layer Security (TLS).
Persistent TLS sets up the connection to the server once and
re-uses that connection for all calls from the phone. The setup
connection for Persistent TLS is established during the
registration of the phone. If the phones are set to use
Persistent TLS, and a call is made from the phone, this call
and all subsequent calls use the same authenticated
connection. This significantly reduces the delay time when
placing a call.
