Hi,
Consider following scenario - Proxy1 and Proxy2 are edge proxies that are DNS resolvable from edge.test.com. DNS resolution does some load balancing and dynamically changes priority of proxy1 and proxy2. A client originates a session over TCP connection to proxy1 after having it resolved as top priority outbound proxy from preconfigured edge.test.com domain. Proxy 1 sends 200 Ok response with following Record-Route header: Record-Route: <sip:edge.test.com;transport=tcp;lr> Now client wants to send a reINVITE and instead of reusing the established TCP connection to proxy1 it resolves edge.test.com over DNS again and this time receives proxy2 as top priority outbound proxy. Having received proxy2 with highest priority than proxy1 client sends in-dialog request to proxy2 instead of reusing established TCP connection to proxy1. Now is there any recommendation for the preferential use of established TCP connection to the proxy1 given that it is resolvable from edge.test.com?
