Cisco ASA/FreePBX One Way Audio Issue

We currently have a Cisco ASA 5505 Firewall and a FreePBX server that is setup.

The ASA is running Version 7.2

I am using ASDM via the GUI to make all my changes (I am a rookie when it comes to Cisco)

When I make calls extension to extension we get two way audio and it works perfectly. However when I make calls directly out from my extension to my cell phone or any other phone outside of our extension the person can hear me but I cannot hear them. The phone call then disconnects the caller but keeps my line open.

I have the ports open on the firewall and I have setup SIP traffic inside the  NAT Policy (see pictures)

My gut tells me this is a NAT issue but my gut has been wrong in the past! PLEASE PLEASE PLEASE HELP!

You might need the allow high-port UDP traffic from outside (from your peer media-gateways) to the FreePBX. SIP is only used for session setup, the actual audio travels in RTP. The port-range used is usually determined by the SIP-trunk setup in Asterisk.
