initiating a fully-attended call transfer (where the
transfer target has answered).

When enabled and the Notify message body is too big
causing fragmentation, the Notify message xml dialog
is simplified; Session Description Protocol (SDP) is
not included in the dialog xml content.
If set to yes, it configures the phone to immediately
handle NOTIFY sipfrag messages.
Display the Diversion info included in SIP message
on LCD or not.
Show the caller ID from the SIP INVITE message
"From" header when set to Yes, even if the call is an
anonymous call. When the parameter is set to no, the
phone displays "Anonymous Caller" as the caller ID.
Supports the content-encoding gzip feature. The
options are none and gzip.
If gzip is selected, the SIP message header contains
the string "Accept-Encoding: gzip", and the phone is
able to process the SIP message body, which is
encoded with the gzip format.
The options are No and Yes. If No is selected, no
changes are made. The default value is No.
If Yes is selected, it disables the display name in
"Directory", "Call History", and in the "To" header
during an outgoing call.
