Summary: dialog route_set contains invalid information

Initial Comment:
When changing the transmission protocol from UDP to TCP and using Record-Routing the resultant route_set in the dialog structure ('route_set' in the dialog or 'caller_route_set' and 'callee_route_set' in the database when using DB dialog persistence) contains a local URI (pointing to the local server)

This seems to be related to a lack of logic in dealing with double record-route situations (like that which occurs when changing the sip transmission protocol)


Here is the "200 OK" from which the callee_route_set will be created

However when we look at callee_route_set the value in the database we see that there is an element that references the local system which shouldn't be there
207.232.98.31:15061 is the local SIP proxy

Database callee_route_set value:
"<sip:207.232.98.31:15061;transport=tcp;r2=on;lr;ftag=16ed1c322255e7feo1;bid=bPP.x3v.E7g>,<sip:65.39.180.33:15061;transport=tcp;r2=on;lr;ftag=16ed1c322255e7feo1;nid=UX0.v9G.Wu3>,<sip:65.39.180.33:15061;r2=on;lr;ftag=16ed1c322255e7feo1;nid=UX0.v9G.Wu3>"

Expected callee_route_set value:
"<sip:65.39.180.33:15061;transport=tcp;r2=on;lr;ftag=16ed1c322255e7feo1;nid=UX0.v9G.Wu3>,<sip:65.39.180.33:15061;r2=on;lr;ftag=16ed1c322255e7feo1;nid=UX0.v9G.Wu3>"
