(CTI) Link
In a private network, operation for calls in PassageWay Telephony Services
applications depends upon the application implementation as well as the type of
private networked trunks (PRI or tie) that carry calls.
For an outgoing call, if the PassageWay Telephony Services application
uses the length of a destination telephone number order to differentiate
PSTN calls from UDP calls, a PassageWay Telephony Services client
displays a non-local extension call in the same way as it does inside calls.
For an outgoing call, if the PassageWay Telephony Services application
uses receipt of the Network Reached event to differentiate PSTN calls from
inside calls, a PassageWay Telephony Services client displays a non-local
extension call or other UDP-routed call in the same way as it does an
outside call made to the PSTN.
For an incoming call, if the PassageWay Telephony Services application
uses the length of Automatic Number Identification (ANI) information to
differentiate PSTN calls from UDP calls, a PassageWay Telephony
Services client displays a non-local dial plan call as an inside call.
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 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 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.
