[SR-Users] Diversion Header - relay messed up

[Roman Dissauer]

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!
