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 

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.
