</div></div>Diversion header is an outdated draft and anyone who follows along with<br>
developments in the SIP community will tell you that other methods such as<br>
history-info are preferred over use of the diversion header.</blockquote><div> </div><div>OK, I see that RFC4244 relates to history-info.<br>I'm adding this here for reference.<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
That being said, in<br>
practice, the diversion header is used by several phones. The firmware on my<br>
Polycom desk phone (IP 430) supports the sending of a Diversion header when it<br>
sends a 3XX response code.<br>
<br>
As far as Asterisk is concerned, current released versions (All 1.4 and 1.6.0)<br>
will read the Diversion header</blockquote><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> in an incoming response and use that information<br>
to fill in the rdnis of the corresponding channel's callerid structure. Once the<br>
changes from <a href="http://reviewboard.digium.com/r/201" target="_blank">http://reviewboard.digium.com/r/201</a> are merged into Asterisk trunk,<br>
then Asterisk will also generate a Diversion header if you have configured<br>
Asterisk to generate redirecting information.</blockquote><div><br>Is it planned to support in Asterisk both history-info and diversion headers ?<br>
(I can't access reviewboard at the moment soI can't check by myself).<br>If positive, that would be interesting to know how mixed diversion/history-info hardphones are treated.<br><br>Are you aware of history-info enabled (hard or soft) phone ?<br>
