Double NAT ?! You may as well try to find a cure for cancer.

Here is my advice ...

- If you must use SIP, don't use NAT
- If you must use NAT, use IAX
- If you must use both SIP and NAT, build a tunnel

Anything else is either not going to work at all, or it will be the
equivalent of building a house using cardboard and duct tape: messy
and unreliable.
