This is not openser specific, but can I just check my understanding of the SIP RFC? Given an INVITE where the Request-URI is different from the To field, a UAS should route the INVITE based on the Request-URI, correct? The reason I ask it that I am having problems integrating openser with a proprietry SIP proxy as the proprietry proxy routes INVITES based on the To field.
