Inbound versus Outbound Phonebooks
To make the VOIP system transparent to phone users and to allow all possible
free and reduced-rate calls, the VOIP administrator must configure the
“Outbound” and “Inbound” phone-books of each VoIP in the system.
The “Outbound” phonebook for a particular VOIP unit describes the dialing
sequences required for a call to originate locally (typically in a PBX in a
particular facility) and reach any of its possible destinations at remote VOIP
sites, including calls terminating at points beyond the remote VOIP site.
The “Inbound” phonebook for a particular VOIP unit describes the dialing
sequences required for a call to originate remotely from any other VOIP sites
in the system, and to terminate on that particular VOIP.
Briefly stated, the MultiVOIP’s Outbound phonebook lists the phone stations it
can call; its Inbound phonebook lists the dialing sequences that can be used to
call that MultiVOIP. (Of course, the phone numbers are not literally “listed”
individually.) The phone stations that can originate or complete calls over the
VOIP system are described by numerical rules called “destination patterns.”
These destination patterns generally consist of country codes, area codes or
city codes, and local phone exchange numbers.
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-
