Hi, Maciej!
The behavior you are describing is exactly how OpenSIPS should behave,
so it's nothing wrong with your setup.
The second affirmation is also right, if you want to change the Contact
header, you have to use topology-hiding, either the one provided by the
dialog module, or the B2B module.

Hello,
I just want to setup Opensips as SIP Proxy node.
Release 1.11.2-notls and DRouting module is already in place.
I just want to ask you what do you think about Contact header
modification in such case.
Some of my incoming INVITEs have only Contact header (describing
originator, like IPPABX for instance) without Record-Route header.
Opensips generates additional Record-Route header but doesn't
modify Contact header at all and such request is sent to
terminator. As an after-effect all subsequent requests properly
match UAs (thanks to the rule hat RR overrides Contact header).
First of all is this how Opensips behaves and there is nothing to
worry about?
What if i dont want to disclose Contact header information passing
transparently to the other side.
I assume that i may use B2B modules or topology-hiding within
dialog module or setup Freeswitch for this purpose, am i right?
Maybe I should play around with opensips script a little to modify
that header?
Thanks in advance,
Maciej
