Hi,
can anyone explain what the "did" parameter in Record-Route header does?
Record-Route: <sip:192.168.0.5;lr=on;ftag=e45c4b13;did=c92.09e2afc1>
I suppose it is inserted in case of a "routing spiral", because it is
inserted when the INVITE request is routed through the proxy a second time.
Cheers
Franz

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
