A early dialog is created by a 1xx response and a confirmed dialog is created by a 2xx response. No response, no dialog. You cannot send a BYE. You cannot send a CANCEL. You just terminate the transaction. You have to assume the INVITE was not received. _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
