asterisk users - Mar 2009 - SIP Diversion header

Hi,

Is anyone aware of SIP Diversion header ?
It seems currently supported by Comverse (formely NetCentrex) softswitch and
some hardphones (Thomson ST2030).

An old draft (draft-levy-sip-diversion-08.txt) mentions this header.

ha

I'm wondering if this could be used

Has this been replaced by something else ?

Diversion header is an outdated draft and anyone who follows along with 
developments in the SIP community will tell you that other methods such as 
history-info are preferred over use of the diversion header. That being said, in
practice, the diversion header is used by several phones. The firmware on my 
Polycom desk phone (IP 430) supports the sending of a Diversion header when it 
sends a 3XX response code.

As far as Asterisk is concerned, current released versions (All 1.4 and 1.6.0) 
will read the Diversion header in an incoming response and use that information 
to fill in the rdnis of the corresponding channel's callerid structure. Once
the
changes from http://reviewboard.digium.com/r/201 are merged into Asterisk trunk,
then Asterisk will also generate a Diversion header if you have configured 
Asterisk to generate redirecting information.
