RTCP Stats in Asterisk 1.8

Hi - I’m using Asterisk 1.8 via PBX in a Flash. I have used asterisk for years now and every since 1.6, I have used the “rtcp set stats on” in order to watch for issues and monitor quality with calls. I have recently had a couple builds with 1.8.8 and even tried 1.8.13 and the command seems to execute, but nothing is displayed on the CLI at the completion of a call like it normally does. RTCP set debug does however list info on the CLI.

Has something changed on this with 1.8 ??
