[OpenSER-Users] Record-Route: "did" - parameter

[Bogdan-Andrei Iancu]

Hi Franz,

The did parameter is used by the dialog module to easily identify 
sequential requests belonging to a dialog (did=dialog ID). This param is 
inserted in the RR header of the initial requests only and it is 
inherited by the sequential requests via the Route header.

regards,
Bogdan
