That violates the rules of TDM rather violently.
It implies that a perfectly valid working call could *break* in the middle,
since the TDM VC it had nailed up would *lose a segment* in the middle,
which might then not be available when the user came back.
Nuh uh... not in *my* network.
Hold is in-band, semantically; it is *not* the province of the transport
