just to be sure: does your device set rport in the INVITE ?
If not, it could explain your issue, and you could force that by using
force-rport in the SIP profile.
Bonus: I dont think you need to do that. If your FS is out of your
local LAN, and using public IP, you can register as many devices on
your local LAN without doing anything special.
The only thing is that FS does some magic to guess that a device is
behind NAT (based on the IPs in the INVITE, on the presence of rport
in the Via field, etc...), and sometimes, the magic is not powerful
enough (if rport is not there for example).
Using force-rport can help.
To check if FS sees a device correctly behind NAT, check the
sofia_contact (sofia status profile <profile name> shows that for all
You should see fs_nat=yes and fs_path should contain the right way to
reach the device (with public Ip and public port).
