[OpenSIPS-Users] Interaction between OpenSIPS as UAC and real UAC

[Bogdan-Andrei Iancu]

Hello,

Please keep the list CC'ed all the time !

You did no inserted the topo hiding triggering in the write place - you 
need to do it only for initial INVITEs ; for sequential requests you 
need the be sure to invoke the match_dialog() function. See:
http://www.opensips.org/html/docs/modules/1.10.x/dialog.html#id295144

It will be helpful to provide more info on what "it is not working" - 
like do you see any changes on the INVITE sent out by OpenSIPS, any 
script errors, etc
