My opensips knowledge is still very basic, so please excuse if it is
some dumb routing mistake made by me.
I suppose you have a problem with routing in-dialog requests. Please
attach your opensips.cfg.

#### B2BUA ###############################################################
#The functionality is obvious from the name and what this service does is
#to hide the network topology from the parties that establish a dialog.
#To achieve this, the B2BUA poses itself in the middle and established dialogs
with both parties.
#Then all it will do next will be to translate a receipt request or reply into
the dialog from the other side and forward it to the peer entity.
