MSRP and High Availability

Following a High Availability (HA) switchover, the new active Oracle Communications Session Border Controller (OCSBC) responds with a TCP RST to the first MSRP message received on an MSRP session that a UA established with the former active OCSBC. This response provides for a timely detection of the HA switchover and enables the UA to re-initiate the MSRP session by sending a SIP re-INVITE. The OCSBC supports this functionality only on Virtual Machines.
