remote VoIP sites, including non-toll calls completed in the PSTN at the 

remote 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 

used to call that MultiVOIP and how those calls will be directed. (Of course, 

the phone numbers are not literally “listed” individually, but are, 

instead, described by rule.) 
Consider two types of calls in the three-city system described above:  

(1) calls originating from the Miami office and terminating in the New 

York (Manhattan) office, and (2) calls originating from the Miami office 

and terminating in New York City but off the company’s premises in an 

adjacent area code, an area code different than the company’s office but 

still a local call from that office (e.g., Staten Island).   
The first type of call requires an entry in the Outbound PhoneBook of 

the Miami VOIP and a coordinated entry in the Inbound phonebook of 

the New York VOIP.  These entries would allow the Miami caller to dial 

the New York office as if its phones were extensions on the Miami PBX. 
The second type of call similarly requires an entry in the Outbound 

PhoneBook of the Miami VOIP and a coordinated entry in the Inbound 

Phonebook of the New York VOIP.  However, these entries will be 

longer and more complicated.  Any Miami call to New York City local 

numbers will be sent through the VOIP system rather than through the 

regular toll public phone system (PSTN).  But the phonebook entries 

can be arranged so that the VOIP system is transparent to the Miami 

user, such that even though that Miami user dials the New York City 

local number just as they would through the public phone system, that 

call will still be completed through the VOIP system. 
This PhoneBook Configuration procedure 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 and other information must be entered 

exactly; otherwise connections will not be made.
