Thanks Michael, I was not aware that REFER could create a dialog aswell. I have briefly come across REFER before, though this was in the context of facilitating call transfer in SIP.
I have now (very quickly) skimmed over RFC 3515 to confirm this dialog creation property. However, I now feel a little puzzled: there seems to be very little difference in purpose behind the SUBSCRIBE and the REFER method; both seem to request notifications in change of some state information. thanks Matt -----Original Message----- From: Michael Procter [mailto:[EMAIL PROTECTED] Sent: 25 January 2006 09:07 To: Matthew Gardiner Cc: [email protected] Subject: RE: [Sip-implementors] Dialog creation by SUBSCRIBE Matthew Gardiner wrote: [...] > Furthermore, would I be right in saying that INVITE and > SUBSCRIBE are the > only requests which are able to create dialogs? REFER may create a dialog (RFC3515 Section 2), but can also be used within a dialog. I think that is about it.
