FTP Services
Both the Headquarters and DVS servers make an FTP service available for fallback use by ShoreTel
Voice Switches. While this does not have to be active on a continuous basis, the FTP site needs to be
active for the fallback capability to work. ShoreTel recommends that the FTP site always be available.
The ShoreTel server also uses the FTP service to transfer prompts between applications.
The IP phones use the FTP server to download configuration information and the application program
when they boot. The IP phones download these files from the server that is controlling the switch
managing the IP phone.
To view the FTP site properties, use the Internet Services Manager. Anonymous FTP access must be
maintained in order for all ShoreTel applications to use it.
SMTP Services
The ShoreTel software uses SMTP to send email notifications (for example, when new client software
is available for installation). The voice mail system uses SMTP to transport composed messages
between the distributed servers. SMTP services are also required by the Event Notification feature.
The ShoreTel installer does not make any specific configurations to the SMTP service. The
applications deposit outbound email on the server for forwarding elsewhere.
For proper operation of the ShoreTel services, the hosting enterprise must have an email server
configured to accept and forward SMTP mail. This is usually the exchange server or primary email
server for the company.
Client Application Server (CAS)
The Client Application Server (CAS) is a ShoreTel proprietary protocol that uses HTTP messages to
communicate between client PCs and ShoreTel servers. The CAS protocol communicates
configuration updates such as call handling mode settings and Outlook integration. Network devices,
such as firewalls and proxies, must not automatically close these pending requests
IP Phone Services
IP phones in a ShoreTel system rely on two services running on the Headquarters server and
distributed servers:
 IP Phone Configuration Service (IPCS)—Runs on all servers.
 IP Phone Display Service/CAS—Runs on all servers.
The IP Phone Configuration Service (IPCS) manages the IP phone configuration process, including
configuration file downloads and the database updates.
WARNING!
If the anonymous access user ID is modified or its password is changed, TMS does not start.
Changing the properties of this user may require you to rebuild the server to recover.
