Symptoms

The customer acquired a license for SIP to SIP-I for a Oracle Communications Session Router that is already in operation.

As per the documentation, it was noted that this can be achieved by adding the following parameter in options: options +sipi-behavior=iam-anm.

Reference: https://docs.oracle.com/en/industries/communications/session-border-controller/9.1.0/configuration/configuring-ocsbc-native-sip-sipi-interworking.html#GUID-CA292CC2-3381-4989-A690-72ACDF62C300

Topic: Configuring the OCSBC for Native SIP-SIPI Interworking

But at the time of adding said parameter, the session-router stopped working and started sending error 485. Could you help us clarify why said parameter had such behavior

ERROR as seen from logs:

Nov 29 00:36:18.587 [SIP] (4) INVITE 20:do_sip_isup_manipulation: pSession not found -------------------------------------> SBC is unable to perform sip_isup manipulation.
