 When I get an INVITE with Diversion Header the Request is forwarded
 without Diversion Header and the Request User is taken from Diversion User.
 Problem is that on the Destination Host I cannot get original Request User
 what is the intended destination!
 Is this intended behaviour? How can I change this behaviour?

 I already tried to delete the Diversion Header on request_route but this
 didn’t change the behaviour.

 Thanks in andvance for your help!

 Hi Daniel,

 For anyone else who might run into this issue I found
 https://github.com/kamailio/kamailio/issues/85 to be related to mine. And
 its a good a starting point.

 Cheers

  HI Daniel,

 modparam("dialog", "dlg_flag", 4) modparam("dialog",
"send_bye", 1)
 modparam("dialog", "timeout_noreset", 1)

 So regular bye's by useragent i can succesfully relay to this
 <sip:6gjlmali@ec2c66jsa0ei.invalid;transport=ws>
 style of uri by using this snippet below

 # Handle requests within SIP dialogs
 route[WITHINDLG] {
   if(is_method("BYE")) {
     xlog("DEBUG: Received BYE");
     route(NATDETECT);
     loose_route();
     dlg_manage();
     t_check_trans();
     handle_ruri_alias();
     rtpengine_delete();
     route(RELAY);
     exit;
   }
 ...

 But the byes that are sent out by dlg_set_timeout("$var(timer)") gives 
out
  error cannot resolve
 the random.uri and I don't know how to fix the bye before it get sent  out.

 Thanks
 Andrew

 Hello,

 isn't the dialog module setting the right value there? What function are
 you using to update the contact?

 Hello,

 Just wondering if it's possible to intercept the bye message that
 dlg_set_timeout sends out to do some nat_helper function to fix it so the
 bye can be sent to random.invalid uris.

 I know there is the edge proxy outbound module but wondering if I can do
 it without.

 Regular bye between 2 clients i was able intercept and fix with nat  helper
  but I dont know how to fix the byes that is sent
out from dlg_set_timeout
 function.

 Thanks in advance!
 Andrew
