MSRP and High Availability

Following a High Availability (HA) switchover, the new active Oracle® Enterprise Session Border Controller (E-SBC) responds with a TCP RST to the first MSRP message received on an MSRP session that a UA established with the former active E-SBC. 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 E-SBC supports this functionality only on Virtual Machines.
