Header
Description
Set this parameter to yes to configure the phone
to immediately handle NOTIFY sipfrag messages.
You can also configure this parameter in the
configuration file:
<Keep_Referee_When_REFER_Failed ua="na">Yes
</Keep_Referee_When_REFER_Failed>
Set to yes to cause the IP phone to parse and
display the Diversion header in the incoming
INVITE messages. The phone displays the
information from the first Diversion header; if there
are multiple Diversion headers, the others are
ignored. The Diversion header follows the
definition from RFC 5806. For example, for this
diversion header in the INVITE messages:
Diversion:
<sip:WeSellFlowers@p4.isp.com>;reason=time-of-
day
The screen should display:
From xxx
12345678
Via: WeSellFlowers.
The reason field in the header is ignored. If the
header field is not properly formed, Diversion
header (all) will be ignored. If the privacy field is
not set or is set to off, only the URI is displayed
due to screen size limitation. If the privacy field is
set to full, "anonymous" is displayed. If the privacy
field is set to name, only the display name is
displayed.
Set to yes to show the caller ID from the SIP
INVITE message "From" header, even if the call is
an anonymous call. When the parameter is set to
no, the phone displays "Anonymous Caller" as the
caller ID.
