The session refresh request is an INVITE within an existing dialog, hence it needs to have the same identifiers as the dialog it is part of. > >From i.e. what will actually happen if the new request will contain > newly > generated Call-ID, To and From? Because it has a different Call-Id, such an INVITE would be considered part of a different dialog, probably a new dialog, unless by chance the Call-Id of the refresh INVITE matched some other dialog. So the INVITE would appear to be an INVITE outside of an existing dialog. But in that case, the recipient would notice that the INVITE has a to-tag, which an INVITE outside of a dialog cannot have. So the request would likely be either rejected as erroneous or would be treated as starting a new dialog.
