Would SIP call drop after switch-over if using TCP instead of UDP

Hi Folks,

Having reading https://community.oracle.com/message/12974248#12974248, at the bottom of the thread,

“The active SBC will synchronize media state to the standby SBC (via the MBCD application), but neither H.323 signaling state (via h323d) nor TCP socket state is replicated. After a switchover you should expect media to continue between calling and called parties as normal, as this flow data is instantiated on the newly-active system. This system will also, as I mentioned, respond to TCP keepalive messages from all interested parties... so any socket-layer keepalives that the endpoints use to confirm connectivity will succeed.

Because TCP socket state is not replicated, however, the next TCP packet with actual signaling that arrives (like a releaseComplete, for example) will cause the newly active SBC to send a TCP RST. This will likely cause the endpoint receiving the RST to tear down the call.”
