Receiving voice calls. Any voice calls directed to the voice or data extension of
a Basic multimedia complex will ring at the voice station.
Receiving multimedia calls. Any data calls directed to the voice or data
extension of a Basic multimedia complex will ring at the multimedia equipped PC
if it is available. You may answer the multimedia call at the PC and voice and
video will connect to the PC. If the data endpoint is unavailable, the system
verifies that the telephone of the complex is administered with the H.320 field set
to
y. If so, the system converts the call to voice and sends it to the telephone of the
multimedia complex, where the call then alerts.
Hourglass Tone. When a voice station answers a converted multimedia call, the
answering party may hear different things depending on the nature of the
originator. If the origination is directly from an H.320 DVC system or if the
originator is an Enhanced mode complex on a remote switch, an immediate audio
path will not exist between the two parties. This is because the H.320 protocol
must be established after the call is answered. It takes several seconds for the
H.320 protocol to establish an audio path. During this interval the answering party
will hear special ringback. When the audio path exists the special ringback will be
removed and replaced with a short incoming call tone indicating that audio now
exists. The combination of special ringback followed by incoming call tone is
referred to as “
hourglass tone.” Hourglass tone is an indication to the answering
party that they should wait for the H.320 call to establish audio.
