Chapter 1
Gateway Routing Manager
The Gateway Routing Manager (CS) enables companies to provide connection
services for communications using the Voice Gatewa y.
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 store s the necessary inf ormation and trac ks which
accounts are currently online.
Features
When a connection request to an e-mail addre ss is made, the CS translates the
requested e-mail address to an IP address so that a direct connect ion bet ween the
caller and the target can be made. When a connection request to a telephone
number is made, the CS returns the addres s for a Voice Gatew ay 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 thr ough
the appropriate Voice Gateway can then be made.
GUI-Based Configuration
Gateway Routing Manager (CS) options can be configured through the Control
Center application. Options such as operator permissions, parent/child
relations hips with othe r CSs, and information for virtual WebPhone accounts can
be added, remov ed, or modified.
Interfa ce with Othe r Da tabases
The CS interfaces with an ODBC compatible SQL server, including Microsoft®
SQL Server® and Oracle Workgroup Server.

Gateway Routing Manager Description
Event and Transaction Logging
As an option, transa ction infor mati on can be logged to the Ev ent 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 r eporting
software.
Real-T im e Event Presentati o n
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 Cryptosyste m™ 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 privile ge s to the CS.
Description
The Gateway Routing Manager (CS) provides component-specific services to
other Voice Service clients and servers, including the Voice Gatew ay. Depending
on the needs of the client or server, the CS can provide connection se rvices,
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 a ddress, IP addr ess, and on line sta tus fi elds, and uses the m
to perform IP address resolution, track account activation information, and more.
1-2
303141-A Rev. 00
Gateway Routing Manager
This allows customers to connect with other partie s 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 Gate way routes calls to a
telephone number, the CS is used to resolv e the telephone number to the IP
address of a Voice Gateway which supports the target te lephone 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 direct s
each call for a virtual WebPhone to the appropria te Voice Gateway fo r processing.
If the Voice Gatewa y goes of f lin e for some re ason, the st atus f or the re lated vir tual
WebPhone processes are updated by the CS.
Account Management
The Gateway Routing Manager (CS) maintains account information, such as
account type, account numb er, and PIN code.
Accounts
Accounts can be set up as an individual account or corporat e 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 tr an saction.

Gateway Routing Manager Description
Once approval is rece ived, the request ed serv ic e is perfo rm ed . Whe n complete,
the server that perfo r me d the ser vic e co nta ct s the CS w ith the final info rm at ion.
The CS updates the user’s account. If an optional Event Manager (EMS) is
available, a detailed rec o rd of the call is sto re d and can be acces sed la ter fo r
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 T i me CS Activi ty 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 Gate way Rou ting Manager (CS) is the centr al component to most Voice
Service networks, two or more C Ss can be arranged in parent/child relationships
to create laye red n et works .
For ex ample , a b usiness could install a local CS in each bran ch office and
configur e them as child servers for a regional CS. Each l ocal CS would be use d to
connect to users on the local group, while the regional server would be used to
connect with other branches in the region.

Security
Gateway Routing Manager
Establishing a secure connection between two syste ms across the Internet is a
signif ic ant task. A system must be assured that it is connected to its intended
recipient sys tem. Communica tions must be prot ected fr om interc eption, playbac k,
decoding, or modification by third parties. Data monitoring, tampering, and
spoof ing pose significant challenges to establishing secur e communications.
Voice Services use the RSA Public Key Cryptosyste m™ to provide secure
communications . A
public ke y crypto system
is a complex mathematical method to
secure digital communications. Public ke y encryption uses two algor ithmic keys:
public key
a
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, whi le unique
keys are genera ted for each indivi dual 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 mus t be distrib uted to ne w Voice Services or Control Centers through
a key management syste m.
System Administration Using the Control Center
The Control Center is the configuration, operation, and management application
that interface s wi th al l Voice Serv i ces. The Control Center is a Microsoft
Windows-based, 32-bit application with a graphical user interface (GUI). It
provides c omponent- specific services for each of the Voice Service products and
also af f ects how some Voice Service client applications f unction.

by name and password when they log into the Control Center. Some of the
permissions that can be enable d 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 Description
The Control Center application keeps track of known servers, the ke y ring of
selected servers, and the local Control Center key ring. Each server and Control
Center has a unique key, and a
av a ilable to a Control Center. Key rings can be saved as file s for backup or
transportation. Ke y administration and management is perf or med 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.
