WIP 300 SIP NO AUDIO

I've done just about everything i can to try and make this work.
I have cable modem for service (COMCAST) but can't seem to find anything to configure in it.
On the internal network audio is fine between the two SIP phones.
Outside of the network....no audio whether one phone is on the internal network or not.

I've got the port forwared on the router:
UDP 5060 - 5082
UDP RTP 10000 - 20000

The IP of the machine running Asterisk is also set to be outside to router firewall.
DMZ: 192.xxx.x.x

The Asterisk program is running on a Mac and the firewall is off.
I really don't know what to do next.
CAN SOMEONE PLEASE HELP ME!!!!!!!!!
