Hello,
if you define an onreply_route[x] to be executed for that invite
transaction, you can execute 'drop' instead of 'exit' and the reply is
not forwarded.
What is tricky is 'relay only last provisional' -- here you should
define the rules specific for the device/your environment and decide
when you need to drop or not -- message flags or htable can be options
to save some states to track whether to drop or not.
Cheers,
Daniel

Hello.
My uplink usually gives ringback as both 183 Progress with SDP and 180
Ringing also with (different) SDP. One of my clients can't handle that
behavior and it just don't plays ringback at all. Is it possible to
relay only last provisional response with SDP and drop anything else
183? Any ideas plz? Can't figure out even a logic itself.
Thanks.
