Understanding Trunk Features
The ShoreTel 6.1 system supports several different trunk types and trunk features. It is
very important to understand the features available on these trunks, since some
services are mutually exclusive. Table 5-2 shows each trunk type and the associated
features.
Legend to Table 5-2
• Yes—Feature is supported.
• No—Feature is not supported.
• Yes (CO)—Feature is provided by the central office (CO) or legacy PBX.
• N/A—Outbound calls are not supported on analog wink-start trunks.
Caller ID Number
Caller ID Number delivers to the ShoreTel 6.1 system the number of the calling party,
which is displayed in the ShoreWare Call Manager as well as on Caller ID–compatible
telephones. The delivery of the caller ID number can be blocked by the calling party.
The caller ID number is delivered unless the calling party has blocked the call (in
which case the call is marked as “Blocked”), or the service provider does not have the
information (in which case the call is marked as “Unavailable”).
Caller ID Number has the following limitations:
• The calling party may block his or her caller ID number.
• The calling party may be calling from a business and the calling number may be
incorrect.
