5.4.1 Caller ID Number
Caller ID Number delivers to the ShoreTel 8 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.
The calling party may be calling from someone else’s number.
Caller ID Number is available on analog loop-start, digital loop-start, SIP, T1 PRI, and E1
PRI trunks.
Two different Caller ID Number formats are used to deliver caller information via loop-start
trunks: Single Data Message Format (SDMF) and Multiple Data Message Format (MDMF).
SDMF provides the calling number, while MDMF provides any combination of calling
name and number. The ShoreGear voice switches support both SMDF and MDMF
dynamically, without the need for configuration. When PRI is used, the caller ID number is
delivered as a D-Channel message.
ShoreTel 8 supports International Caller ID, ensuring that when a switch is configured for a
certain site (e.g. Spain), the International ID information is automatically filled in as
appropriate for that country. The feature is transparent from the user's standpoint, and no
configuration is necessary.
5.4.2 Caller ID Name
Caller ID Name delivers the name of the calling party to the ShoreTel 8 system. The name is
displayed in the ShoreWare Call Manager as well as on any telephones that support caller
ID Name.
By default, the caller ID name is delivered unless the calling party has blocked the transfer
of this information (in which case the call is marked as “Blocked”). If the service provider
does not have the information, the call is marked as “Unavailable.”
Caller ID Name is available on analog loop-start and digital loop-start trunks, as well as SIP,
T1 PRI, and E1 PRI trunks and is only supported on IP phone and analog phones in North
America. This feature is not supported on analog phones in other countries.
b. Caller ID Name is supported for NI-2 configured trunks.
c. *67 and *82 codes do not work if the CO requires a pause between the code and the
dialed number.
