[SIPForum-discussion] Dialog Without a Session

[Óê ³Â]

Hi, You'd better have a look at the RFC3621 (section 12)~~~  As the session is set up for media transmission (video,audio.game etc) while a dialog just represents a peer-to-peer SIP relationship that persists for some time. I think U can find out a valid dialog in the followed situation:
  1.       early dialog: 101-199 responses to INVITE ;
  2.       non-failure responses to request for extension method (eg.NOTIFY) ;
  3.       Hold on a call during a existed session.

  I would like to know if there is any possibility of having a valid DIALOG without any Session Getting established.
  Please provide me with the flow if possible.

  There are two choices in life, one to accept things as they exist, and second to accept the responsibility to change them.
