Description Martin Prpič 2014-11-21 13:17:22 UTC

The following issue was made public in the AST-2014-014 advisory [1][2]:

The ConfBridge application uses an internal bridging API to implement
conference bridges. This internal API uses a state model for channels
within the conference bridge and transitions between states as different
things occur. Under load it is possible for some state transitions to be
delayed causing the channel to transition from being hung up to waiting for
media. As the channel has been hung up remotely no further media will
arrive and the channel will stay within ConfBridge indefinitely.

Patches for this issue are linked to in the AST-2014-014 [1][2] advisory.
