    							MultiVOIP User Guide T1 PhoneBook Configuration
    281
    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-end connection.  The phone station originating the
    call must be connected to the VOIP system.  The Outbound Phonebook
    for that VOIP unit must have a destination pattern entry that includes
    the ‘called’ phone (that is, the phone completing the call).  The Inbound
    Phonebook of the VOIP where the call is completed must have a
    destination pattern entry that includes the digit sequence dialed by the
    originating phone station.   
    The PhoneBook Configuration procedure  below 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, destination patterns, and
    other information must be entered exactly; otherwise connections will
    not be made.

    Phonebook Configuration Procedure
    1.  Go to the PhoneBook Configuration screen  (using either the sidebar
    menu, drop-down menu, or icon).
    In consultation with your VOIP administrator, enter the Gateway
    Name and values for Q.931 parameters and Gatekeeper RAS
    parameters. Determine whether your voip system will operate with a
    proxy server.  Determine which H.323 version 4 functions you will
    implement. (They are not always applicable.  See field description for
    each parameter.)

    The table below describes all fields in the PhoneBook Configuration
    screen.  
    PhoneBook Configuration Parameter Definitions
    Field Name Values Description
    Gateway
    NameY/N This field allows you to specify a name for
    this MultiVOIP.  When placing a call, this
    name is sent to the remote MVP3000 for
    display in Call Progress listings, Logs, etc.
    Q.931 Parameters
    Use Fast Start Y/N Enables the H.323 Fast Start procedure.
    May need to be enabled/disabled for
    compatibility with third-party VOIP
    gateways.
    Call Signalling
    Portport
    numberDefault: 1720 (H.323)
    GateKeeper RAS
    Parameters
    IP AddressIP address of the GateKeeper.
    Port Number Well-known port number for GateKeepers.
    Must match port number of GateKeeper,
    1719.
    Gateway
    PrefixThis number becomes registered with the
    GateKeeper.  Call requests sent to the
    gatekeeper and preceded by this prefix will
    be routed to the VOIP gateway.
    Gatekeeper
    Namealpha-
    numeric
    stringOptional.  The name of the GateKeeper with
    which this MultiVOIP is trying to register.
    H.323 ID The H.323 ID is used to register this
    particular MultiVOIP with the GateKeeper.
    H.323 ID is an alias entry sent to the
    GateKeeper, made of alpha-numeric
    characters.  For NetMeeting endpoints,
    numbers are preferred over letters.  The
    H.323 ID identifies the IP calling sequence
    that the GateKeeper must ‘dial’ to contact
    the remote VOIP.

    IP Addressn.n.n.n

    n=0-255Network address of the proxy
    server that the voip is using.
    Port Number Logical port number for proxy
    communications.
    H.323 Version 4 Parameters
    Q.931
    Multiplexing
    (Mux)Y/N Signalling for multiple phone
    calls can be carried on a single
    port rather than opening a
    separate signalling port for
    each call.  This conserves
    bandwidth resources.
    H.245
    Tunneling
    (Tun)Y/N H.245 messages are
    encapsulated within the  Q.931
    call signalling channel.
    Among other things, the H.245
    messages let the two endpoints
    tell each other what their
    technical capabilities are and
    determine who, during the
    call, will be the client and who
    the server. Tunneling is the
    process of transmitting these
    H.245 messages through the
    Q.931 channel. The same
    TCP/IP socket (or logical port)
    already being used for the Call
    Signalling Channel is  then also
    used by the H.245 Control
    Channel.  This encapsulation
    reduces the number of logical
    ports (sockets) needed and
    reduces call setup time.

    H.323 Version 4 Parameters
    Parallel H.245
    (FS + Tun)Y/NFS (Fast Start or Fast Connect)
    is a Q.931 feature of H.323v2 to
    hasten call setup as well as
    ‘pre-opening’ the media
    channel before the CONNECT
    message is sent.  This pre-
    opening is a requirement for
    certain billing activities.
    Under Parallel H.245 FS + Tun,
    this Fast Connect feature can
    operate simultaneously with
    H.245 Tunneling (see
    description above).
    Annex –E (AE) Y/NMultiplexed UDP call
    signalling transport.  Annex E
    is helpful for high-volume voip
    system endpoints.  Gateways
    with lesser volume can afford
    to use TCP to establish calls.
    However, for larger volume
    endpoints, the call setup times
    and system resource usage
    under TCP can become
    problematic.  Annex E allows
    endpoints to perform call
    signalling functions under the
    UDP protocol, which involves
    substantially streamlined
    overhead.  (This feature should
    not be used on the public
    Internet because of potential
    problems with security and
    bandwidth usage.)
