[OpenSIPS-Users] How to pass in-dialog data with topology_hiding?

[Bogdan-Andrei Iancu]

Hi Alexey,

MAybe you should try to add some kind of parameter to the Contact URI - 
TH is replacing the hostport parts, not the full URI (double check it 
please :D). The Contact URI will be received back as RURI.
