Sorry to rebuke you Jerry, but you are wrong in this case.

nat=yes doesn't solve the outbound problem, when using asterisk as a
sip client inside a NAT.

We need stun support for that situation to figure out what kind of
NAT we have between us and the SIP proxy, and to set the proper
IP address (the IP address of the NAT's public side).

A STUN client *will* help us automatically replace the
localnet/externip settings we have today.

A stun server can be run alongside with Asterisk on the same server
today if your SIP clients (inside a NAT device) need STUN.

And no, I am not aware of anyone developing a STUN client for Asterisk.
