I used to work with the 2nd edition Nokia sip stack. Upon the receipt of an Invite with a route header, the stack was automatically generating a record-route header in the 200 OK.
With the third edition SIP stack, I get the invite and see that the reply (the 200 ok) has no longer the record-route header which, of course, causes problem on the server.
Am I missing something? is there anyway to enable the record-route header to be inserted ?
