/*** DOCUMENTATION
<function name = "AUDIOHOOK_INHERIT" language="en_US">
<synopsis>
DEPRECATED: Used to set whether an audiohook may be inherited to another
channel. Due to architectural changes in Asterisk 12, audiohook inheritance
is performed automatically and this function now lacks function.
</synopsis>
<description>
<para>Prior to Asterisk 12, masquerades would occur under all sorts of
situations which were hard to predict. In Asterisk 12, masquerades only
occur as a result of a small set of operations for which inheriting all
audiohooks from the original channel is now safe. So in Asterisk 12.5+,
all audiohooks are inherited without needing other controls expressing
which audiohooks should be inherited under which conditions.</para>
