SS7 as well as sip allow for remote hold. No media is transmitted at that point in Sip you save bandwidth in TDM you don't eat up a channel
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 mechanism. Cheers, -- jra -- Jay R.
