SCA - Not Handling an "INVITE" Followed Immediately By the "BYE" Message on SIP Dialogue (Doc ID 2214516.1)

Last updated on DECEMBER 22, 2016

Applies to:

Oracle Communications Network Charging and Control - Version 4.4.1 and later
Information in this document applies to any platform.

Symptoms

On all versions of Oracle Communications Network Charging and Control (OCNCC or NCC) and Oracle Communications Convergent Charging Controller (OC3C), the Oracle Session Control Agent (SCA) is not responding to SIP (Session Initiation Protocol) "INVITE" messages from Metaswitch.
The problem appears when the Metaswitch (MS) from A-Party sends an "INVITE" to disconnect media towards SCA, followed almost immediately by the "BYE" message.
