I'm trying to REGISTER on my SER server with the Grandstream Handy Tone but
the Grandstream support STUN end when it register to my SER it register with
the internal IP instead of the WAN. The Grandstream is behind a Linksys
Cable/Router. I have about 20 Cisco ATA 186 with no problem... Any
suggestion, does some body has any good script for the nathelper for this
problem.....
