■ For an incoming call, if the PassageWay Telephony Services application
uses the presence of a trunk identifier in the
delivered event
to differentiate
PSTN calls from UDP calls, a PassageWay Telephony Services client
displays a non-local dial plan call in the same way it does a PSTN call.
■ For an incoming PSTN call that enters the private network on a PRI trunk
with an ANI of length shorter than seven digits and crosses PRI tandem
trunks only, the recipient PassageWay Telephony Services client display
depends on the PassageWay Telephony Services application
implementation:
— If the Passageway Telephony Services application does not strip leading
zeros, the recipient Passageway Telephony Services client displays in
the ANI information any leading zeros needed to make the information
seven digits long.
— If the Passageway Telephone Services application strips leading zeros,
the recipient Passageway Telephony Services client displays the ANI
information in its original length. The call displays as an inside or outside
call depending on whether ANI information or a trunk identifier in the
delivered event
is used to differentiate the call.
If the non-local dial plan recipient of a transfer or conference call is a PassageWay
Telephony Services client, the recipient’s display shows caller information about
the conference or transfer originator, not any other caller.
Users at CTI-linked PassageWay Telephony Services extensions must use the
telephones at their extensions to make transfers to non-local dial plan extensions
or to add conferees to a conference. They cannot use their PassageWay
applications. A PassageWay Telephony Services client display does not provide
an indication when a non-local conferee is dropped.
Collected digits are not sent across the private network.
The examples in Chapter 2, “Call-Handling Scenarios,” provide details about and
examples of how PassageWay Telephony Services clients operate in a private
network.
Conference 3
Calls to a non-local dial plan extension are treated as outside calls for the purpose
of conferencing. Each non-local conference participant who is added takes up one
of the two outside calls permitted in a conference. For example, if a user has
added two outside calls to a conference, it is not possible to add a non-local
extension.
