Chapter 1 Location Server Configuration
1.1 Overview
A location server (LS) stores device and number information, answers queries about
the information from a process server (PS), and manages the media server (MS).
Figure 1-1 shows the architecture of the XE IP PBXs.

Figure 1-1 Architecture of the XE IP PBXs
A PS, LS and MS communicate with each other via call application interface (CAI)
proprietary protocol interface. After receiving a register request from a gateway (the
gateway in this manual refers to H.323 gateway and SIP user agent client, unless
otherwise noted), the PS exchanges such messages as query, response, notification,
and indication with the LS. And after receiving a call request from a gateway, the PS
queries the LS for number information through CAI message.
The device information on an LS is configured by an administrator, while the number
information on the LS is configured by an administrator or reported by gateways
through PS.
1.2 Functionality and Features
1.2.1 LS Functionality
zUniformly assigning number resources

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration
1-2
Number resource is traditionally assigned at the gateway side, and this method is not
efficient. The feature of assigning number resource uniformly is designed to resolve this
problem. By design, each gateway has a factory-set port number. Bund with the
gateway’s ID, the port number is mapped to a number during configuration. By this
means, the LS can implement number assignment, making it easy for maintenance.
This feature supports only POTS (plain old telephone service) users.
zQuerying device information and sending a response
SIP Registrar or H.323 gatekeeper needs to gain the IP PBX’s device information from
LS when authenticating register requests from the IP PBX. It sends requests of
querying device information to LS, and the request carries gateway ID or address.
Then the LS returns device information to the SIP Registrar or H.323 gatekeeper by
sending a query response after the device information is retrieved.
zQuerying a number and sending a response
Before sending a session request to a called number, a SIP proxy server or H.323
gatekeeper needs the called information corresponding to the number. It sends number
query request to an LS, then the LS returns information corresponding to the number to
the SIP proxy server or H.323 gatekeeper by sending a query response after the
information is retrieved.
zConfiguring PS information
You must configure the following PS information on the LS: PS ID (SIPServer or H.323
gatekeeper), the number of the portwhere the PS receives RASpackets, the number of
the port where the PS receives SIP packets, the ID of the group to which the PS
belongs, heartbeat password, whether multiplexing is enabled, whether tunneling is
enabled, the relative capability value of the PS group, and the domain that the device
belongs to.
zQuerying PS information
By specifying a PS ID, you can query the information about the PS or list the
information about all PSs, including: IP address and port number, ID and the ID of the
group to which the PS belongs, heartbeat password, transmission mode for SIP
packets, and register status.
zConfiguring MS information
You need to configure MS information on the LS, including the MS ID, heartbeat
password and language type that the MS supports.
zConfiguring gateway information
You can configure the information of a gateway (SIP User Agent or H.323 gateway)
registered with an LS, which includes the following information: gateway identifier,
gateway type, whether a dynamic IP address is used, IP address and port number of
the gateway, IP address and port number of H.323 gateway call signaling, device status,
transport layer protocol of SIPUA, default route priority, static route number and priority,

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration
1-3
whether authentication is enabled, authentication password, manufacturer information,
whether multiplexing is enabled, registering cycle, and so on.
Note:
If calling number hiding is configured on a gateway acting as a SIP user agent, services
related with the calling number may not work.
zQuery gateway information
To query the gateway information, you can provide the identifier of the gateway; also
you can list information about the gateway by device type.
zConfiguring office device information
You need to configure the information of an office device configured on an LS, which
includes: office device identifier, device type, device status, IPaddress and port number,
static route number, default route priority, and whether multiplexing is enabled.
zQuerying information about office device
To query the office device information, you can provide the identifier ofthe office device;
also you can list information about the office device by device type.
zConfiguring office group information
You need to configure the information of an office group on an LS, including office group
identifier, area code, domain to which the office group belongs, static route, number
substitution table, and so on.
zQuerying information about office group
You can query the information of an office group by the office group identifier.
zQuerying devices corresponding to a number
You can query the devices that support a specific number.
zEnabling/disabling LS functions
You can enable/disable an LS to meet different network requirements of PS and LS. If
the PS function and LS function are enabled on the same XE IP PBX, you must enable
the LS function. If the PS function and the LS function are enabled on different XE IP
PBXs, you must disable LS function on the XE IP PBX serving as PS. If LS function was
enabled on the PS IP PBX and now you have disabled it, all the dynamic information
record will be lost on the LS, and new registrations and calls will fail, but the calls that
have already been set up will not be affected, and the LS function should be enabled on
the XE IP PBX serving as the LS.
zSpecifying call processing method

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration
1-4
You can specify the call mode (redirect call mode or routed call mode) for SIP calling
or H.323 calling on the LS. In the redirect call mode, the PS registered with the LS
works in redirect mode; and in the routed call mode, the PS works in proxy mode.
Note:
When the SIP call mode is adopted, if CLIR (calling line identification restriction) is
enabled on the gateway, services that related with calling line may work improperly.
zQuerying statistics information about an LS
You can query the statistics information about an LS, including the statistics about the
messages received/transmitted by internal and external modules, and error count.
1.2.2 LS Features
The LS supports:
zNetworking with H3C’s SIP Server and H.323 gatekeeper
zNetworking with the H.323 gatekeeper from other vendors
zManagement on SIP Server or H.323 gatekeeper
zNetworking with H3C’s SIP devices and H.323 devices
zDynamic IP gateways
zManagement on gateways (including SIP user agent and H.323 gateway)
zCAI proprietary protocol
zWhen the XE 200 IP PBX functions as an LS, up to 1600 gateways, 3200
subscriber numbers and 3200 routes can be configured on the XE 200; at most
eight PSs can be cascaded.
zWhen the XE 2000 IP PBX functions as an LS, up to 16000 gateways, 32,000

party, and the call is placed under the control of the PS and the LS. In redirect mode,
the PS directly responds with the IP address ofthe called party to the calling party (if the
IP address of the called party is stored in the LS), and then the calling party calls the
called party.
Note:
For networks containing both H.323 and SIP devices, you need toset call mode of both
SIP Server and gatekeeperas “routed” to achieve interworking between SIP and H.323
terminals.
Perform the following configuration in LS view.

Note:
zIf you use the manufacturer command to set the manufacturer of the gateway to
other, the system will disable the dynamic update of the gateway’s IP address.
zAfter enabling the dynamic update of the gateway’s IP address with the dynamic-ip
command, you cannot use the manufacturer command to change the
manufacturer setting of the gateway; in addition, the ip-address, port, call-signal
ip-address, and call-signal port commands become invalid.
Table 1-11 Specify whether a gateway uses a dynamic IP
Operation Command
Specify whether a gateway uses a
dynamic IP address dynamic-ip {disable |enable}
Restore the default setting undo dynamic-ip
IV. Configuring the IP address of a gateway
The IP address of a gateway here is the one recorded on the LS. To ensure a proper
connection, you must set the IP address of the gateway identical to the actual one on
the gateway.
Perform the following configuration in LS-GW view.
Table 1-12 Configure the IP address of a gateway
Operation Command
Configure the IP address of a gateway ip-address ip-address
Delete the IP address of the gateway undo ip-address
V. Configuring the port number of a gateway
The port number of a gateway here is the one recorded on the LS. The LS
communicates with the gateway through this port, and thus the port number configured
on the LS for this gateway must be identical to the one configured on the gateway. For
SIP, the port number is 5060 (default); and for H.323, it is 1719 (default).

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration

Note:
By default, the port number is 5060. When the dynamic-ip disable command is used
and the type of the gateway is SIP, you can keep this number unchanged; while if the
type is h323, you must use the port command to set the port number to 1719 (default).
Perform the following configuration in LS-GW view.
Table 1-13 Configure the port number of a gateway
Operation Command
Configure the port number of a gateway port port
Restore the default port number undo port
VI. Configuring the IPv4 address of the call signaling for a gateway
By default, the gateway reports information to the LS dynamically. When you configure
the gateway to register with the XE IP PBX in static mode, the gateway device type is
H.323, and the gateway status is set to normal or forever-up, you must configure the
IP address of the call signaling.
Perform the following configuration in LS-GW view.
Table 1-14 Configure the IPv4 address of the call signaling for a gateway
Operation Command
Configure the IPv4 address of the call
signaling for a gateway call-signal ip-address ip-address

Operation Command
Configure the call signaling port of a gateway call-signal port port
Restore the default setting undo call-signal port
VIII. Configuring the status of a gateway
The status of gateway is the primary parameter of PS and LS gateways recorded by an
LS. There are three states all together: normal, suspend, and forever-up.
In normal state, a gateway must successfully register to be able to interact with the PS
registered with an LS. Besides, it needs to register regularly according to the timeout
interval configured on the LS.
In suspend state, a gateway can neither register successfully, nor interact with any PS
registered with an LS. PS will provide no service to this type of gateway.
In forever-up state, a gateway can utilize services provided by PSs and LSs without
registration.
Note:
To configure a gateway to forever-up state, you need to configure:
The PS which the gateway belongs to. For configuration of the PS, refer to the “Process
Server Configuration Operation” module of this manual.
zIPv4 address and port of the call signaling for the gateway. Refer to Configuring the
IPv4 address of the call signaling for a gateway and Configuring the call signaling
port of a gateway.
Perform the following configuration in LS-GW view.
Table 1-16 Configure the status of a gateway

IX. Configuring the transport layer protocol used by SIP UA
Note:
This configuration is unavailable to H.323 gateways.
A SIP gateway communicates a PS using a certain transport mode. XE IP PBX
supports TCP and UDP transport modes. Three parameters are available: auto, tcp,
and udp. In auto mode, TCP protocol is be used first; if it fails, UDP protocol will be
used. As for tcp and udp modes, you must set a transport mode identical to the actual
one. If you have no idea how data are transported, you can set the mode to auto.
Perform the following configuration in LS-GW view.
Table 1-17 Configure the transport layer protocol used by the gateway
Operation Command
Configure the transport layer protocol to be used by
a gateway transport {auto |tcp |udp }
Restore the default transport layer protocol undo transport
By default, UDP protocol is used when the gateway functions as the SIP user agent.
Note:
When configuring simultaneous ringing for multiple called parties, you must configure
the transport mode to tcp or udp using the transport command.
X. Configuring the default route number priority of a gateway
If you have not configured route priorities for the number resource of the gateway, you
can use the default priority of the current gateway as the priority of number resource.
Perform the following configuration in LS-GW view.
Table 1-18 Configure the default route priority of a gateway
Operation Command
Configure the default route priority of a
gateway priority level
Restore the default priority undo priority

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration
1-14
The default value of the route priority is 10. The larger the value is, the higher the
priority will be.
XI. Configuring the static route number of a gateway
When a user calls a number and you have set a static route number for a gateway or an
office device configured on an LS, the request will be forwarded to the gateway or office
device for query. When multiple numbers that comply with a certain rule are to be
routed to the same device, you can configure a regular expression to match these static
numbers to decrease the length of the LS’s routing table, improve the LS’ executing
efficiency, and shorten the LS’ responding time.
Note:
When using the regular expression to match the dialed number, the system
automatically begins the match from the beginning of the regular expression. If the first
judgment is true, the match goes on; otherwise, the match fails. You do not needto add
a caret (^) at the beginning of the expression, because the system has added it by
default. For details about the regular expression, refer to the Basic Configuration part of
the H3C XE 200/2000 IP PBX Operation Manual.
Perform the following configuration in LS-GW view.
Table 1-19 Configure the static route number of a gateway
Operation Command
Configure the static route number of a
gateway prefix number
Delete one or all static route numbers undo prefix {number |all }
Note:
When configuring the static route number, make sure that it does not conflict with the
ONLY number, the automatic operator number and the group notification number. For
detailed information, refer to the “Call Services Operation” module of this manual.
XII. Specifying whether a gateway needs to perform authentication
The LS can determine whether to authenticate register and call requests sent from the
UA. If authentication is disabled, the UAcan register with the registrar and place voice
calls without authentication; if authentication is enabled, the UA must pass the
authentication first.

Operation Manual – Location Server Configuration
H3C XE 200/2000 IP PBX Chapter 1 Location Server Configuration

Note:
Authentication is currently available to SIP-supported devices. As for H.323 devices, it
is a reserved parameter.
Perform the following configuration in LS-GW view.
Table 1-20 Specify whether a gateway needs to perform authentication
Operation Command
Specify whether a gateway needs to
perform authentication authentication {disable |enable }

XIII. Configuring the authentication password of a gateway
After you have configured authentication passwords on an LS and a gateway
respectively, the PS will check whether the authentication password of the gateway is
identical to that recorded on the LS when the gateway performs registration and
initiates a call, so as to ensure the validity of the gateway identification.
Note:
Authentication is currently available to SIP-supported devices only. As for H.323
devices, it is a reserved parameter. An authentication password is valid only when
authentication is enabled, although it is configurable when authentication is disabled.

1.3.10 Configuring an Office on an LS
For an LS domain, office devices are devices that do not report device information but
have reachable routes to the LS of this domain. The office device contains the number
information needed by the LS, but the office device does not belong to the LS domain.
The office device can be an H.323 gateway, gatekeeper, a SIP server, or a SIP user
agent. Office devices outside an LS domain form one or several office groups, each
containing multiple office devices. An office device must belong to some office group.
To configure an office on the LS, you must create an office group and enter
LS-OFFICEGROUP view first. In this view, you can configure the office information
including:
zConfiguring the domain to which an office group belongs
zConfiguring the static route number of an office group
zAdding an office device or enter an office view
In LS-OFFICEGROUP-OFFICE view, you can configure the following:

I. Adding an office group or enter an office group view
With the office-group command, you can enter office group view of the specified office
group, or create the specified office group if it does not exist and then enter its office
group view.
Perform the following configuration in LS view.
Table 1-23 Add an office group or enter an office group view
Operation Command
Add an office group or enter an office
group view office-group office-group-id
Delete one or all office groups undo office-group {office-group-id | all }
II. Configuring the domain to which an office group belongs
Refer to Creating a domain for the information about domain.
Perform the following configuration in LS-OFFICEGROUP view.
Table 1-24 Configure the domain to which the office group belongs
Operation Command
Configure the domain to which the office group belongs belongto domain-id
Specify that the office group belongs to the
default-domain domain undo belongto
By default, an office group belongs to the default-domain domain.
III. Configuring the static route number of an office group
A static route number is a regular expression. When a user calls a number and you
have set a static route number for a gateway or an office device configured on an LS,
the request will be forwarded to the gateway or office device for query. When multiple
numbers that comply with a certain rule are to be routed to the same device, you can
configure a regular expression to match these static numbers to decrease the size of
the LS’s routing table, improve the LS’ executing efficiency, and shorten the LS’
responding time.
Each static route number has a priority value, ranging from 0 to 1000 and defaulting to
that of the office device. The greater value enjoys the higher the priority. You can
configure an identical static route number for several different office devices (multiple
called parties). If the priorities of the called numbers are the same, the corresponding
telephones will ring simultaneously when the number is called. If the priorities are not
the same, the telephones will ring orderly.

Perform the following configuration in LS-OFFICEGROUP view.
Table 1-25 Configure the static route number of an office group
Operation Command
Configure the static route number of an office group prefix number
Delete one or all static route numbers of an office
group undo prefix {number |all }
Note:
When configuring the static route number, make sure that it does not conflict with the
ONLY number, the automatic operator number and the group notification number. For
detailed information, refer to the “Call Services Operation” module of this manual.
Caution:
The XE IP PBX does not support cyclic route check.
For example:
zOn the LS A, map the static route number 8801 to the office PS B.
zOn the LS in the LS domain where the PS B resides, map the static route number
8801 to PS C.
zOn the LS in the LS domain where the PS C resides, map the static route number
8801 to PS D.
z…
zOn the LS in the LS domain where the PS N-1 reside, map the static route number
8801 to PS N.
zOn the LS in the LS domain where the PS N resides, map the static route number
8801 to a certain PS in the LS A domain.
After the above configurations are completed, cyclic route will occur, thereby reducing
the network performance. Therefore, it is recommended not to perform such
configurations.
IV. Adding an office device or enter an office view
If a specific LS-OFFICE view already exists, you can enter it directly; if not, you must
create a new one first, and then enter it.
With the office command, you can enter office view of the specified office device, or
create the specified office if it does not exist and then enter its
LS-OFFICEGROUP-OFFICE view.
