Trying to figure out how to get the equivalent behavior of fs_path, but only for a single transaction. In other words, I want to start a SIP request hitting a particular proxy, and then simply let Record-Route headers determine where the call should be routed after that.

I might be completely overthinking this, but everything I've tried so far (sip_route_uri, fs_path), have resulted in Freeswitch continuing to use the given route for all subsequent requests, rather than simply falling back to the session route.

Am I missing something?

Best,

Colin
