"""\
Interface for channels where you may put the channel on hold.
This only makes sense for channels where
you are streaming media to or from the members. (To see whether the
other participant has put you on hold, see CallState.)
If you place a channel on hold, this indicates that you do not wish
to be sent media streams by any of its members and will be ignoring
any media streams you continue to receive. It also requests that the
connection manager free up any resources that are only needed for
an actively used channel (e.g. in a GSM or PBX call, it will be
necessary to place an active call on hold before you can start
another call).

"""
Request that the channel be put on hold (be instructed not to send
any media streams to you) or be taken off hold.
If the connection manager can immediately tell that the requested
state change could not possibly succeed, this method SHOULD
return the NotAvailable error. If the requested state is the
same as the current state, this method SHOULD return successfully
without doing anything.
Otherwise, this method SHOULD immediately set the hold state to
Local_Hold_State_Pending_Hold or Local_Hold_State_Pending_Unhold
(as appropriate), emitting
HoldStateChanged if this is a change,
and return successfully.
The eventual success or failure of the request is indicated by a
subsequent HoldStateChanged signal, changing the hold state to
Local_Hold_State_Held or Local_Hold_State_Unheld.
If the channel has multiple streams, and the connection manager
succeeds in changing the hold state of one stream but fails to
change the hold state of another, it SHOULD attempt to revert
all streams to their previous hold states.
The following state transitions SHOULD be used, where
appropriate:
Successful hold:
(Unheld, any reason) → (Pending_Hold, Requested) →
(Held, Requested)
Successful unhold:
(Held, any reason) → (Pending_Unhold, Requested) →
(Unheld, Requested)
Attempting to unhold fails at the first attempt to acquire a
resource:
(Held, any reason) → (Pending_Unhold, Requested) →
(Held, Resource_Not_Available)
Attempting to unhold acquires one resource, but fails to acquire
a second, and takes time to release the first:
(Held, any reason) → (Pending_Unhold, Requested) →
(Pending_Hold, Resource_Not_Available) →
(Held, Resource_Not_Available)

RequestHold, or the state changing as a
result of a request from
