If your asterisk server is on a WAN IP, then you may not even need STUN. Add
qualify=yes
nat=yes
to the sip.conf entry for each device.

This will have asterisk ignore the IP in the SIP packets and look at
the TCP header. Also, qualify will send a 'keep-alive' to keep NAT
from losing the association of ports.
