<p>I think I understand a little bit more my problem.</p>
<p>"From" Header is corrected in Request Route, but it is another request that will be sent to the UA. The transaction isn't forwarded and From Header is regenerated from transaction memory!</p>

<p>The debug section in request route:</p>

<p>Have you got any idea how to modify the generated packet? Or how to change the "From" Header generated locally</p>
<p></p>
<p>Thanks</p>

<p>> Good Morning,</p>
<p>> I'am using a loadbalanced platform with dispatcher module. When a packet is</p>
<p>> sent from a Gateway to a peer, I rewrite the From Header which contains the</p>
<p>> IP of the gateway in order to put the proxy domain because some Hardphones</p>
<p>> like</p>
<p>> Thomson ST2030 will keep the domain in call history to be able to call back</p>
<p>> a person. If the UA use the direct IP of the gateway, the call will failed,</p>
<p>> it has to go through the proxy! So I would like to rewrite From header</p>
<p>> coming from gateways</p>
<p>></p>
<p>> It's working for INVITE, OPTIONS,... in main route, but CANCEL packets are</p>
<p>> not rewritten and UA sent back a message saying transaction does not exists</p>
<p>> because From header is different from INVITE!</p>
<p>></p>
<p>> I have put this in main route:</p>
<p>></p>
<p>> if (ds_is_from_list()) { # Returns true if the current request comes</p>
<p>> from a host from the dispatcher-list</p>
<p>> xlog("L_INFO", "Rewriting From Domain in $rm $(hdr(From))");</p>
<p>> #subst('/^From:(.*)@xxx.xxx.xxx.[0-9]+(.*)$/From:</p>
<p>> \1@xxx-dev.xxx.xx\2/ig');</p>
<p>> }</p>
<p>></p>
<p>> Have you got any idea how to rewrite CANCEL packet?</p>
<p>> I have tried to put the same thing in failure route but it does not work.</p>
<p>></p>
<p>> Thanks</p>
<p>></p>
<p>> Best Regards</p>
