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, starting on page
3.3.3 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, starting on page 287.
3.3.4 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, starting
on page 207.
3.3.5 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. The maximum number is 4 BB24
devices per multiline phone.
Step 3 Determine the number of ports for fax machines and modems.
Step 4 If you are deploying IP phones, determine the number of telephones that will
be IP phones and the number that will be analog phones.
Certain users will require access to certain features, such as an operator
needing a phone with programmable buttons. Therefore, you should consider
which type of functions each user will need in order to select the most
appropriate phone for that user.
