will always send 180 Ringing and after that the 183 Session Progress.

Is there any way to  configure the system to behave as in version 1.4.21.1?

The show stopper for me is the new behaver. I known that - there is no
problem to send 180 Ringing before sending the 183 Session Progress
and if there is a problem it is in the other device, not in the
Asterisk.

Also is the new behaver (1.4.2X+) presented in all new versions of
Asterisk 1.6+/1.8+?
