■ To use Direct Voice Mail, the calling extension and the called extension
must be on the same system.
■ Leave Word Calling only works only if the calling extension, called
extension, and covering voice mail for the called extension are on the same
system. For 6.1 and later systems, when a centralized VMS is located on a
remote system from the calling extension and called extension, incorrect
confirmation messages and no error tones may indicate that Leave Word
Calling succeeded but no message is sent to the called extension.
■ Return Call for MLX and analog multiline telephones does not work across
the private network.
■ For Coverage Inside and Coverage VMS OFF, non-local dial plan calls are
treated as outside calls.
■ When Night Service is routed to a centralized VMS/AA in a different time
zone, or where the offices have different hours, the service received
(automated attendant greeting) depends on the time where the centralized
VMS/AA is located. The automated attendant greetings should be
programmed appropriately.
■ A QCC operator can provide overflow coverage for an integrated VMI
calling group on the system with the centralized VMS/AA. In this case, the
operator will hear call information signals (touch-tones) meant for the voice
messaging system indicating that you need more VMI ports.
■ When a caller leaves a message or when a non-local subscriber retrieves
all messages, the centralized VMS/AA sends the Message Waiting light
updates across the private network.

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.
