That's a workaround not a proper solution.
The requirement stated was "secure and reliable".

The only proper solutions are:

1) If you must use SIP, don't use NAT
2) If you must use NAT, use IAX instead of SIP
3) If you cannot avoid neither NAT nor SIP, build a VPN tunnel,
preferably IPsec.

anything other than those are hacks.
