Hi Jeroen, In outbound-11, the UAC includes the 'ob' parameter in its Contact in dialog-forming requests if it wants the first-hop to Record-Route with a flow token. This language is flexible enough that it allows an implementation to use a GRUU in its contact instead (once it has one), to implement outbound without GRUU, and to send an initial SUBSCRIBE for the SIP config event package before registration. I believe this addresses your comment. thanks, -rohan On Jul 20, 2007, at 11:45 AM, Jeroen van Bemmel wrote: > Rohan, > > The flag is needed, but you could make it a header parameter rather > than a URI parameter (both for Contact and for Path). > > There is no need for it to appear in the request URI of mid-dialog > requests.
