rfc 3261 section 12.1 Creation of a Dialog, 12.1.1 UAS behavior:

The route set MUST be set to the list of URIs in the Record-Route header
field from the request, taken in order and preserving all URI
parameters.

section 2.2 Requests within a Dialog, 12.2.1 UAC Behavior:

If the route set is not empty, and the first URI in the route set
contains the lr parameter (see Section 19.1.1), 
the UAC MUST place the remote target URI into the Request-URI and MUST
include a Route header field containing the route set values in order,
including all parameters.

to me this means that there cannot be any extra entries in the route
header of bye.
