What's the benefit of using stund vs nat=yes in your sip.conf
for that device? I haven't had any issues behind firewalls
when I enable that option, and no ports are needed to be opened.
For some strange reason, even with nat=yes sometimes when a user's IP
changes, the phone doesn't realise it and sends another SIP refresh.
Asterisk promptly ignores it since there's no registration from that IP.
With stun, the phone realises it's IP has changed and sends an invite to
asterisk rather than a refresh.
I could be wrong, but using stun seems to have improved the nat-related
issues some of our customers have had with their home-based phones no end.
Having a STUN client embedded in Asterisk makes a lot of sense.
