I experimented with it a while ago in my lab and the setup is no longer active. There's no out of the box solution for this, as you need to craft proper Route, Record-Route and Via headers based on the direction of the call. You need to understand how loose routing works in order to set correct headers in outgoing requests. Regards, Ovidiu Sas On Wed, Jun 29, 2011 at 12:14 PM, MingHon <gminghon(a)gmail.com> wrote:

As I mentioned before, based on direction of the call you may or may not need to force an advertised IP/port (see the advertised_address core parameter and set_advertised_address() core function) Also, you will need to force the same IP in the Route/Record-Route headers (see the rr module). And also you will need to put proper IPs in SDP (see the rtpproxy module). Start with a simple config, make calls, check all the SIP requests, find out what's not properly set and fix the config.
