The asterisk side has to have the router ports 5060 and 10000-20000 forwarded to asterisk  these are the standard ports but you could cut way down on the rtp  ports in rtp.conf then you have to tell asterisk what's the external ip of your nat and most of the times this should work today no problem lots of us here have it working that way (of course you have to take care of security fail2ban etc )
On the phone side you might have to use stun but it depends on the firewall also you should set the phone to send a nat keep alive each 30 seconds (asterisk also sends a options packet to keep the nat open but doesn't always work ok )
