Call Flow Control broken failing

I’m using PIAF with FreePBX on two systems with Call Flow Control Call flow is fails when its set to dial an outside number.

The big difference between the two systems is asterisk & kernel versions:
OLD build that Works is using asterisk & kernel 2.6.32-220.2.1.el6.i686
NEW build that Fails is using asterisk & kernel 2.6.32-220.17.1.el6.i686

There’s no errors appearing in the logs or asterisk cml. It just sits there claiming to have connected but no audio or communication capable. The receiving number doesn’t even ring, so its not connecting.

Anybody else running into this or know a fix?
