Site D calling Site C
1.
 Dial 9,15077175662.
2.
 “9” gets outside line.  On some PBXs, an “8” may be used to
direct calls to the VOIP, while “9” directs calls to the PSTN.
However, some PBX units can be programmed to identify the
destination patterns of all calls to be directed to the VOIP.
3.
 PBX at Site D is programmed to divert all calls made to the 507
area code and exchange 717 into the VOIP network.  (It would
also be possible to divert all calls to all phones in area code 507
into the VOIP network, but it may not be desirable to do so.)
4.
 The MVP2400/2410 removes the prefix “1507” and adds the
prefix “101#” for compatibility with the analog MultiVOIP’s
phonebook scheme.  The “#” is a delimiter separating the
analog VOIP’s phone number from the digits that the analog
VOIP must dial onto its local  PSTN to complete the call.  The
digits “101#7175662” are forwarded to the Site B analog VOIP.
5.
 The call passes through the IP network (in this case, the
Internet).
6.
 The call arrives at the Site B VOIP.  This analog VOIP receives
this dialing string from the MVP2400/2410: 101#7175662.  The
analog VOIP, seeing the “101” prefix, uses its own channel #1
(an FXO port) to connect the call to the PSTN.  Then the analog
VOIP dials its local phone number 7175662 to complete the call.

Site D calling Site F
A voip call from Pierre PBX to extension 7424 on the key telephone system in Lincoln,
Nebraska.
A. The required entry in the Pierre Outbound Phonebook to facilitate
origination of the call, would be 1402263742.  The call would be directed to
the Lincoln voip’s IP address, 200.2.9.5.
(Generally on such a call, the caller would have to dial an intial “9.”  But
typically the PBX would not pass the initial “9” to the voip.  If the PBX did
pass along that “9” however, its removal would have to be specified in the
local Outbound Phonebook.)
B. The corresponding entry in the Lincoln Inbound Phonebook to facilitate
completion of the call would be
1402263742  for calls within the office at Lincoln
1402  for calls to the Lincoln local calling area (PSTN).
Call Event Sequence
1. Caller at Pierre dials 914022637424.
2. Pierre PBX removes “9” and passes 14022637424 to voip.
3. Pierre voip passes remaining string, 14022637424 on to the Lincoln
voip
at IP address 200.2.9.5.
4. The dialed string matches an inbound phonebook entry at the
Lincoln voip, namely 1402263742.
5. The Lincoln voip rings one of the three FXS ports connected to the
Lincoln
key phone system.
6. The call will be routed to extension 7424 either by a human
receptionist/
operator or to an auto-attendant (which allows the caller to specify
the
extension to which they wish to be connected).

Site F calling Site D
A voip call from a Lincoln key extension to extension 3117 on the PBX in Pierre, South
Dakota.
A. The required entry in the Lincoln Outbound Phonebook to facilitate
origination of the call, would be “31”.  The string “1615492” would have to be
added as a prefix.   The call would be directed to the Pierre voip’s IP address,
200.2.9.9.
B. The corresponding entry in the Pierre Inbound Phonebook to facilitate
completion of the call would be 1615492.
1. Caller at Lincoln picks up phone receiver, presses button on key
phone set.  This button has been assigned to a particular voip
channel (any one of the three FXS ports).
2. The caller at Lincoln hears dial tone from the Lincoln voip.
3. The caller at Lincoln dials 3117.
4. The Lincoln voip adds the prefix 1615492 and sends the entire
dialing string, 16154923117, to the Pierre voip
at IP address 200.2.9.9.
5. The Pierre voip matches the called digits 16154923117 to its
Inbound Phonebook entry “1615492” .
6. The Pierre PBX dials extension 3117 in the office at Pierre.
Variations in PBX Characteristics
The exact dialing strings needed in the Outbound and Inbound
Phonebooks of the MVP2400/2410 will depend on the capabilities of
the PBX.  Some PBXs require trunk access codes (like an “8” or “9” to
access an outside line or to access the VOIP network).  Other PBXs can
automatically distinguish between intra-PBX calls, PSTN calls, and
VOIP calls.
Some PBX units can also insert digits automatically when they receive
certain dialing strings from a phone station.  For example, a PBX may
be programmable to insert automatically the three-digit VOIP identifier
strings into calls to be directed to analog VOIPs.
The MVP2400/2410 offers complete flexibility for inter-operation with
PBX units so that a coherent dialing scheme can be established to
connect a company’s multiple sites together in a way that is convenient
and intuitive for phone users.  When working together with modern
PBX units, the presence of the MVP2400/2410 can be completely
transparent to phone users within the company.

Phonebooks
Important
Definition:The MultiVOIP’s Outbound phonebook
lists the phone stations it can call;
its Inbound phonebook describes the
dialing sequences that can be used to
call that MultiVOIP and how those calls
will be directed.
When a VOIP serves a PBX system, the operation of the VOIP should be
transparent to the telephone end user and savings in long-distance
calling charges should be enjoyed.  Use of the VOIP should not require
the dialing of extra digits to reach users elsewhere on the VOIP
network.  On the contrary, VOIP service more commonly reduces
dialed digits by allowing users (served by PBXs in facilities in distant
cities) to dial their co-workers with 3-, 4-, or 5-digit extensions -- as if
they were in the same facility.  More importantly, the VOIP system
should be configured to maximize savings in long-distance calling
charges.  To achieve both of these objectives, ease of use and maximized
savings, the VOIP phonebooks must be set correctly.
NOTE: VOIPs are commonly used for
another reason, as well:  VOIPs
allow an organization to
integrate phone and data traffic
onto a single network.  Typically
these are private networks.

Free Calls:  One VOIP Site to Another
The most direct use of the VOIP system is making calls between the
offices where the VOIPs are located.  Consider, for example, the Wren
Clothing Company.  This company has VOIP-equipped offices in
London, Paris, and Amsterdam, each served by its own PBX.  VOIP
calls between the three offices completely avoid international long-
distance charges.  These calls are free.  The phonebooks can be set up to
allow all Wren Clothing employees to contact each other using 3-, 4-, or
5-digit numbers, as though they were all in the same building.

Local Rate Calls:  Within Local Calling Area of Remote
VOIP
In the second use of the VOIP system, the local calling area of each
VOIP location becomes accessible to all of the VOIP system’s users.  As
a result, international calls can be made at local calling rates.  For
example, suppose that Wren Clothing buys its zippers from The
Bluebird Zipper Company in the western part of metropolitan London.
In that case, Wren Clothing personnel in both Paris and Amsterdam
could call the Bluebird Zipper Company without paying international
long-distance rates.  Only London local phone rates would be charged.
This applies to calls completed anywhere in London’s local calling area
(which includes both Inner London and Outer London).  Generally,
local calling rates apply only within a single area code, and, for all calls
outside that area code, national rates apply.  There are, however, some
European cases where local calling rates extend beyond a single area
code.  Local rates between Inner and Outer London are one example of
this.  (It is also possible, in some locations, that calls within an area code
may be national calls.  But this is rare.)

National Rate Calls:  Within Nation of Remote VOIP Site
In the third use of the VOIP system, the national calling area of each
VOIP location becomes accessible to all of the VOIP system’s users.  As
a result, international calls can be made at national calling rates.  Again,
significant savings are possible.  For example, suppose that the Wren
Clothing Company buys its buttons from the Chickadee Button
Company in the Dutch city of Rotterdam.  In that case, Wren Clothing
personnel in both London and Paris could call the Chickadee Button
Company without paying international long-distance rates;  only Dutch
national calling rates would be charged.  This applies to calls completed
anywhere in The Netherlands.

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.
