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!

This behavior is AFAIK not something that kamailio does out of the box
and is just plain wrong (since the Diversion indicates the source of a
forward/deflection). Maybe somebody made a typo to set $ru to $di
instead of $du :)
What may work is calling msg_apply_changes after the delete:

Just tried, but it doesn’t help.
request_route {

} else {
xlog("L_INFO","[$fU@$si:$sp]{$rm} Incomeing Request... with
Diversion Header: $di, Request URI: $ru\n");
remove_hf("Diversion");
if (msg_apply_changes()) {
if (is_present_hf("Diversion")) {
xlog("L_INFO","[$fU@$si:$sp]{$rm} This damn
header is still there!!\n");
}
}
}

Call is being received, Diversion Header is deleted, in RELAY route I print Diversion
header (there it is null).
When I call t_relay() I still get wrong INVITE:
INVITE sip:436761234567@x.x.x.x:5060 SIP/2.0
From: <sip:+43987654321@y.y.y.y>;tag=gK04715d90

seems that $tu is taken instead of $ru when doing t_relay()
Diversion Header has e164 with leading + and to Header has just e164.
Thanks,
Roman

There should be something in the config file that changes the $ru,
kamailio internally doesn't do it if no function in config does it.
To see what it is executed in config file, load debugger module and set
its parameter cfgtrace to 1.
Then in the syslog you should see what lines are executed. You can send
those log messages here and we can provide hints which of the action may
change the $ru.
Cheers,
Daniel
