[OpenSIPS-Users] Does create_dialog behave differently on 1.6 than on 1.7?

Hello Duane,
Got them.
The problem with your script is that the dialog gets created before the
time you fix the nated contact. In your script, you call trace_dialog()
before fixing the contacts, which internally creates the dialog. Thus,
when the script reaches the create_dialog("PpB") part, the dialog is
already there, with the old Contact info.
