In Oracle Communications Converged Application Server (OCCAS) seeing inconsistent behavior with the Min-SE validation as per RFC-4028:
The Min-SE header field indicates the minimum value for the session interval, in units of delta-seconds. When used in an INVITE or UPDATE request, it indicates the smallest value of the session interval that can be used for that session. When present in a request or response, its value MUST NOT be less than 90 seconds.
When the header field is not present, its default value is 90 seconds.
The following call flow shows 2 re-INVITE (CSeq 130 and 131). Both contain a Min-SE value of 0. However, the first re-INVITE passes and the second fails per the spec.
