Usage
Enables rejection of messages on Core Network Service Authorization failure. By default, this feature is
disabled.
In a mobile originating case, S-CSCF checks for the presence of P-Preferred-Service (PPS) header. If the
header is present, media profile authentication is successful and if the incoming ICSI (IMS Communication
Service Identifier) value also matches with one of the values in the service_id list, then the request will be
forwarded after replacing the PPS header with PAS (P-Asserted-Service). If media profile authentication
fails, S-CSCF will check reject-on-cnsa-failure. If enabled, then call is rejected with 403 message. If disabled,
a default ICSI is selected from the service_id list and will be put into PAS while forwarding the request by
the S-CSCF on service authentication failure.
In PPS is not received by the S-CSCF and media profile authentication is successful, an ICSI from the
service_id list, if present, is selected and will be added in PAS header. If media profile authentication fails,
reject-on-cnsa-failure is checked. If enabled, call is rejected with 403 message. If disabled, PAS header is
added if service_id list is present with an ICSI value.
