Site D calling Site C
1.  Dial 901189435632.
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 118
area code and exchange 943 into the VOIP network.  (It would
also be possible to divert all calls to all phones in area code 118
into the VOIP network, but it may not be desirable to do so.)
4. The MVP3010 removes the prefix “0118” 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#9435632” 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 MVP3010: 101#9435632.  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 9435632 to complete the call.
NOTE: In the case of Reading, Berkshire,,
England, both “1189” and “1183” are
considered local area codes.  This is, in a
sense however, a matter of terminology.
It simply means that numbers of the
form 9xx-xxxx and
3xx-xxxx are both local calls for users at
other sites in the VOIP network.

Site D calling Site F
A voip call from Inner London PBX to extension 7424 on the key telephone system in
Tavistock, UK.
A. The required entry in the London Outbound Phonebook to facilitate
origination of the call, would be 90182263742.  The call would be directed to
the Tavistock voip’s IP address, 200.2.9.5.  (Generally on such a call, the caller
would have to dial an initial “9”.  But typically the PBX would not pass the
initial “9” dialed 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 Tavistock Inbound Phonebook to facilitate
completion of the call would be
0182263742  for calls within the office at Tavistock
01822  for calls to the Tavistock local calling area (PSTN).
Call Event Sequence
1. Caller in Inner London dials 901822637424.
2. Inner London voip removes “9” .
3. Inner London voip passes remaining string, 01822637424on to the

at IP address 200.2.9.5.
4. The dialed string matches an inbound phonebook entry at the
Tavistock voip, namely 0182263742.
5. The Tavistock voip rings one of the three FXS ports connected to
the Tavistock
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 Tavistock key extension to extension 3117 on the PBX in Inner
London.
A. The required entry in the Tavistock Outbound Phonebook to facilitate
origination of the call, would be “3”.  The string 02073988 is added, preceding
the “3”.  The call would be directed to the Inner London voip’s IP address,
200.2.9.9.
B. The corresponding entry in the Inner-London Inbound Phonebook to
facilitate completion of the call would be 020739883.
1. The caller in Tavistock picks up the phone receiver, presses a
button on the key phone set.  This button has been assigned to a
particular voip channel.
2. The caller in Tavistock hears dial tone from the Tavistock voip.
3. The caller in Tavistock dials 02073983117.
4. The Tavistock voip sends the entire dialed string to the Inner-
London voip
at IP address 200.2.9.9.
5. The Inner-London voip matches the called digits 02073983117to its
Inbound Phonebook entry “020739883, ” which it removes.  Then it
adds back the “3” as a prefix.
6. The Inner-London PBX dials extension 3117 in the office in Inner
London.
Variations in PBX Characteristics
The exact dialing strings needed in the Outbound and Inbound
Phonebooks of the MVP3010 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 MVP3010 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 MVP3010 can be completely transparent to
phone users within the company.

International Telephony Numbering Plan Resources
Due to the expansion of telephone number capacity to accommodate
pagers, fax machines, wireless telephony, and other new phone
technologies, numbering plans have been changing worldwide.  Many
new area codes have been established; new service categories have been
established (for example, to accommodate GSM, personal numbering,
corporate numbering, etc.).  Below we list several web sites that present
up-to-date information on the telephony numbering plans used around
the world.  While we find these to be generally good resources, we
would note that URLs may change or become nonfunctional, and we
cannot guarantee the quality of information on these sites.
