[Asterisk-biz] Consutant Needed: Direct ip 2 ip call in a centrex

[Are]

There is a problem when the two clients are behind NAT.

canrinvite=yes will not work as the two clients are not aware of the other
clients private IP.

We have sorted this out in two sites by using a small asterisk server in
each site and Switch in extensions.conf . Just old hardware and no
performance but it is not a nice solution. To much work on each site.

If you know how to rewrite SIP packet Headers this can be done in theory.
:-) but I have not had a real good reason to do it.
