IVC Card Features and Support
Chapter 9
Port Sharing
The Integrated Voice Services (IVS) Port Sharing feature enables several callers to
share the same Integrated Voice Controller (IVC) device (port), which improves
the efficiency of port use. With this feature, multiple calls can access a port to allow
different callers to listen to the same message at the same time. IVS messages can be
requested by either a command (step) in a call guide or by the Whisper Messaging
function.
An IVS message consists of one or more phrases. Two messages are identical if they
contain the same IVS phrases in the exact same order. IVS Port Sharing activates when
two or more calls request an identical message from the same IVS group.
The IVS Port Sharing feature requires a delay between the time a first call requests a
message and when an IVC device plays the message. The delay allows a window of
opportunity for other calls to request the same message. After the delay, a single IVC
device plays the same message for all calls that requested it.
Port sharing is not possible for a port that, based on the call guide for a current call, must
collect digits.
IVS Port Sharing Parameters
Two IVS group parameters enable and control IVS Port Sharing. See "Create an IVS
Group" or "Modify an IVS Group" for a procedure to define these parameters.

Port Sharing Parameter
Description
Share Wait Time
The duration that the PointSpan switch waits for other
requests for an identical message before having an IVC
device play that message. The value of this parameter can
be from 1 to 60,000 ms or "None," which disables Port
Sharing. The default is 200 ms.
Maximum Count for Share
The total number of calls that can share a single IVC
device. Upon getting requests for a single message from
that number of calls, the PointSpan switch immediately
stops waiting and has an IVC device play the message to
all of the calls. The value of this parameter can be from 1
to 1000 or "None," which allows each single IVC device to
support unlimited calls at the same time. The default is 5.
