MultiVOIP User Guide E1 PhoneBook Configuration
215
In order for any VOIP phone call to be made, there must be both an
Inbound Phonebook entry and an Outbound Phonebook entry that
describe the end-to-end connection. The phone station originating the
call must be connected to the VOIP system. The Outbound Phonebook
for that VOIP unit must have a destination pattern entry that includes
the ‘called’ phone (that is, the phone completing the call). The Inbound
Phonebook of the VOIP where the call is completed must have a
destination pattern entry that includes the digit sequence dialed by the
originating phone station.
The PhoneBook Configuration procedure below is brief, but it is
followed by an example case. For many people, the example case may
be easier to grasp than the procedure steps. Configuration is not
difficult, but all phone number sequences, destination patterns, and
other information must be entered exactly; otherwise connections will
not be made.
