asterisk users - Mar 2015 - Asterisk removes SDP from 180 with SDP

Asterisk receives a 180 Ringing with SDP from the called side, then it sends 180
without SDP to the calling side.

We would like asterisk to sends to the calling side the same response that was
received from the called side.
This is Asterisk cert 13.1, is that a new behavior, is there a setting to change
this ?


?
