Change the SIP port to 5070 and the RTP ports to 10000-10100, and
forward all UDP traffic on those ports to the Siemens' IP.
Remember also to use - where possible - an Outbound proxy, and not to
have registrations refresh too often.
By default, the "Registration refresh time:" on Gigaset is 180 seconds,
that means that by RFC the refresh is made at 75% of that, so one
registration every minute and a half or thereabouts. Too likely to fail.
I set that parameter to 600 or even 1200, and the "NAT refresh time" to
the maximum of 999 - you don't need it if you open the ports on your router.
