Hi,
When I told you about ACL, it was because this is a normal
misunderstanding.
ACL helps to determinate what is considered as a local and external address.
Have you checked if the INVITE arrives with an IP address within your local
network?
If so, that will produce a 200 OK response with an local IP into the SDP
message .
use tcpdump, ngrep or any other tool to determinate IP addresses involved
in your scenario.
Regard,
