On switchover, media set-up for playback is preserved, which requires negotiated codec and ptime for playback be transferred to the stand-by system in an HA node.

Regarding playback after switchover:

• When configured using SPL, any playback in progress will not be continued on switchover.
• When configured using ACLI, the system restarts active playback media on switchover.

While standard configuration replication handles transferring configuration information between the active and standby systems, media playback files (in /code/media) must be loaded onto the standby.
