If you forward like this:
Public IP  ---> Private IP

You should forward port 5060 + the UDP range used in rtpproxy/mediaproxy.
Use advertised_address directive in addition to listen.
The standard getting started NAT configs assumes that you have no local 
user agents, and just do far-end NAT traversal.
