Chapter 1
Gateway Routing Manager
The Gateway Routing Manager (CS) enables companies to provide connection
services for communications using the Voice Gateway.
The Gateway Routing Manager (CS) is the center of most Voice Services
networks. The CS allows Voice Gateways to contact other parties by e-mail
address and IP address. The CS stores the necessary information and tracks which
accounts are currently online.
When a connection request to an e-mail address is made, the CS translates the
requested e-mail address to an IP address so that a direct connection between the
caller and the target can be made. When a connection request to a telephone
number is made, the CS returns the address for a Voice Gateway which supports
the number, based on the E.164 telephone number, specifically, the country code,
area code, and subscriber number. A connection to the telephone number through
the appropriate Voice Gateway can then be made.
Features
GUI-Based Configuration
Gateway Routing Manager (CS) options can be configured through the Control
Center application. Options such as operator permissions, parent/child
relationships with other CSs, and information for virtual WebPhone accounts can
be added, removed, or modified.
Interface with Other Databases
The CS interfaces with an ODBC compatible SQL server, including Microsoft®
SQL Server® and Oracle Workgroup Server.

Gateway Routing Manager Description
1-2 303141-A Rev. 00
Event and Transaction Logging
As an option, transaction information can be logged to the Event Manager (EMS).
Information such as the number of database resolution queries, the query length,
or the party called can be used to generate reports using third-party reporting
software.
Real-Time Event Presentation
The CS reports real-time data, such as the number of connect requests, to the
Control Center application.
Secure Communications
Voice Services use the RSA Public Key Cryptosystem™ to provide secure
communications and prevent problems such as data interception, playback,
decoding, and modification by third parties.
System Administration
Control Center users are identified by unique user names and encrypted
passwords. Users can be given all, some, or no administrative privileges to the CS.
Description
The Gateway Routing Manager (CS) provides component-specific services to
other Voice Service clients and servers, including the Voice Gateway. Depending
on the needs of the client or server, the CS can provide connection services,
manage accounts, or display information and statistics. Network hierarchy and
security functions are used to structure and coordinate secure connections
between Voice Service products.
Gateway Routing Manager Services
The Gateway Routing Manager (CS) functions as a dynamic IP address lookup
service and user information manager for other Voice Service products. The CS
updates the user e-mail address, IP address, and online status fields, and uses them
to perform IP address resolution, track account activation information, and more.

Gateway Routing Manager
303141-A Rev. 00 1-3
This allows customers to connect with other parties by e-mail address as well as
by IP address, as IP addresses may be dynamic and difficult to remember. In
addition, the CS allows customers to connect with other parties by telephone
number through a Voice Gateway which supports the target telephone number.
The Voice Gateway is chosen by the CS based on the E.164 telephone number of
the call.
Processing Calls
When the Voice Gateway routes a call to an e-mail address, the CS is used to
resolve the target e-mail address. And when a Voice Gateway routes calls to a
telephone number, the CS is used to resolve the telephone number to the IP
address of a Voice Gateway which supports the target telephone number.
Maintaining Records
The Voice Gateway, using virtual WebPhone processes, can publish a destination
(such as a conventional telephone) as well as an e-mail address. The CS directs
each call for a virtual WebPhone to the appropriate Voice Gateway for processing.
If the Voice Gateway goes offline for some reason, the status for the related virtual
WebPhone processes are updated by the CS.
Account Management
The Gateway Routing Manager (CS) maintains account information, such as
account type, account number, and PIN code.
Accounts
Accounts can be set up as an individual account or corporate account. All
accounts are identified by an account number and PIN code, and individual
accounts are also identified by an e-mail address.
Transaction Processing
When a Manager (usually the Voice Gateway) requests a transaction, it contacts
the CS for account information. Depending on the type of the account, the CS
either approves or denies the proposed transaction.

Gateway Routing Manager Description
1-4 303141-A Rev. 00
Once approval is received, the requested service is performed. When complete,
the server that performed the service contacts the CS with the final information.
The CS updates the user’s account. If an optional Event Manager (EMS) is
available, a detailed record of the call is stored and can be accessed later for
customer history or other reports.
Display Information and Statistics
The CS uses the main display and an events monitoring dialog box of the Control
Center application to display account and connect request information.
Figure 1-1. Monitor Real Time CS Activity Dialog Box
The Monitor Real Time CS Activity Dialog Box (Figure 1-1) displays the number
of users coming online and going offline, connect requests, ID change requests,
and Control Center applications coming on line and going offline.
Network Hierarchy
While the Gateway Routing Manager (CS) is the central component to most Voice
Service networks, two or more CSs can be arranged in parent/child relationships
to create layered networks.
For example, a business could install a local CS in each branch office and
configure them as child servers for a regional CS. Each local CS would be used to
connect to users on the local group, while the regional server would be used to
connect with other branches in the region.

Security
Establishing a secure connection between two systems across the Internet is a
significant task. A system must be assured that it is connected to its intended
recipient system. Communications must be protected from interception, playback,
decoding, or modification by third parties. Data monitoring, tampering, and
spoofing pose significant challenges to establishing secure communications.
Voice Services use the RSA Public Key Cryptosystem™ to provide secure
communications. A public key cryptosystem is a complex mathematical method to
secure digital communications. Public key encryption uses two algorithmic keys:
a public key used to encode the data and a private key required to decode it. The
encryption key is usually made public and the decryption key is kept secret.
Voice Services use two additional types of keys to create two levels of security.
Default keys are common to all Voice Services and Control Centers, while unique
keys are generated for each individual Voice Service and Control Center. To
communicate with other Voice Services, a Voice Service or the Control Center
must have the appropriate security keys. All Voice Services and Control Center
applications have the default key when installed; if the default key is disabled,
unique keys must be distributed to new Voice Services or Control Centers through
a key management system.
System Administration Using the Control Center
The Control Center is the configuration, operation, and management application
that interfaces with all Voice Services. The Control Center is a Microsoft
Windows-based, 32-bit application with a graphical user interface (GUI). It
provides component-specific services for each of the Voice Service products and
also affects how some Voice Service client applications function.

Administrative Access
Each Voice Service maintains a list of authorized users, and each user is validated
by name and password when they log into the Control Center. Some of the
permissions that can be enabled or disabled when assigning user access include:
• Add and Delete Control Center Users
• View and Change Server Configuration
• Monitor Real-Time Statistics

Gateway Routing Manager
303141-A Rev. 00 1-7
Gateway Routing Manager Configuration Options
The Control Center interface displays several options that enable you to configure
operating parameters and features. You can:
• Specify the database information, such as database name, login information,
and number of database licenses.
• Specify the debug filename and location, and the information to be logged.
• Specify server information, such as host name and IP address.
A host is a computer system (with a unique IP address and domain name) that
can function as the beginning and end point of data transfers.
• Specify information for an optional primary and secondary parent CS.
The Gateway Routing Manager (CS) can be configured to distribute services
over a hierarchical tree with CSs acting as “parents” to subordinate clients and
servers (for more information, refer to the Control Center Administration
Guide).
• Specify information for optional child CSs.
A child is a subordinate client or server of “parent” Gateway Routing
Managers in a distributed services system (for more information, refer to the
Control Center Administration Guide).
• Specify information for an optional primary and secondary Event Manager
(EMS).
RSA Security Management
Voice Services use the RSA Public Key Cryptosystem™ to provide secure
communications. In order to communicate with other Voice Services, a server or
the Control Center must have the appropriate security keys. All Voice Service and
Control Center applications have the default key when installed; if the default key
is disabled, unique keys must be distributed to new servers or Control Centers
through a key management system.

Gateway Routing Manager Description
1-8 303141-A Rev. 00
The Control Center application keeps track of known servers, the key ring of
selected servers, and the local Control Center key ring. Each server and Control
Center has a unique key, and a key ring is the collection of all unique keys
available to a Control Center. Key rings can be saved as files for backup or
transportation. Key administration and management is performed through the
Control Center to keep keys updated. The administrator should periodically
generate new keys and share updated keys with servers and clients that require
them.
