Summary:                    Add netfilter functionality to asterisk to plumb NAT
holes for RTP when running on NATting router
Description: 
Where:

* Asterisk is running on an "edge" device which is also the
firewall/router,
* and NAT is being used for SIP endpoints behind the firewall/PBX,
* and SIP transport is being used for trunking/peering on the "outside" as
well, such that INVITES pass "through" the Asterisk platform,

it might be useful to add logic where Asterisk plumbs NAT holes for the
RTP stream, then modifies the SDP information in the SIP INVITE messages to
reflect the external address and port #'s.

If you'd like to discuss a potential architecture for doing this in a way
that we could accept, let's talk on the asterisk-dev list.  Thanks!
