Planning and System Design
Planning and Installation Guide 3 – 3
Even though there are multiple servers, the ShoreTel 6.1 system provides a single image
system across your entire network. The system is currently certified to support up to 21
servers, one at the headquarters site and up to 20 distributed servers. You should add a
server at any site that exceeds 100 users. You must deploy a server for every 1,000
users.
The distributed voice applications platform can also provide an open applications
platform for extending telephone services through TAPI-compliant third-party
applications. A dedicated distributed server is required to host the third-party
applications. This server is deployed like other distributed servers, except that it must
not have voice mail users assigned to it.
The distributed voice application servers’ Remote TAPI Service Provider relies on the
call control information from the main server. To add reliability to your remote server,
consider using redundant network paths to the main server.
For information about the ShoreWare server requirements, see Chapter 10, “Server
Requirements.”
Citrix and Windows Terminal Server
Citrix and Windows Terminal Server (WTS) technologies enable processing for
multiple users to be aggregated on a single Windows computer. The single Windows
computer is a process- and disk-sharing server for multiple users who have lightweight
or thin graphics stations on their desktop. Citrix communicates between the server and
clients using the ICA protocol, whereas Windows Terminal Server uses the RDP
protocol.
For more information on configuring ShoreWare Call Manager clients on Citrix and
WTS servers, see Appendix E, “ShoreWare Clients on Citrix and Windows Terminal
Servers.”
Teleworker Sites
In addition to the main locations, you can also deploy ShorePhone IP phones at
employees’ homes for the purpose of telecommuting. This allows teleworkers complete
access to all the voice services on the network. The number and location of each
teleworker IP phone should be noted on the topology diagram.
For information on configuring ShoreTel IP phones as teleworkers, see Chapter 15, “IP
Phone Installation.”
Telephone Requirements
The next task in the system design process is to determine your telephone
requirements.
To determine your telephone requirements:
Step 1 Count the telephones that are needed by counting the users installed
on your current system. Make sure to include conference room
telephones, lobby telephones, and telephones shared by multiple users.
Step 2 Determine the number of button boxes (ShoreTel BB24 devices) that
will be needed for operators and receptionists.
