ShoreTel 14.2 Planning and Installation Guide 95
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 ShoreTel
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 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.
Caller ID Name
Caller ID Name delivers the name of the calling party to the ShoreTel system. The name is displayed in
the ShoreTel Communicator 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.
When using NI-2 signaling on PRI trunks — for example in a tie-trunk scenario — Caller-ID Name is
now also captured when available on all inbound calls. For outbound calls, Caller-ID Name is delivered
for calls that are made to off-system extensions, but not for outbound calls.
Automatic Number Identification (ANI)
Automatic Number Identification (ANI) delivers the number of the calling party to the ShoreTel system.
Although similar to Caller ID Number, ANI is tariffed differently and is not subject to the same blocking
restrictions as Caller ID Number. For example, when you purchase ANI services from your service
provider, you are always delivered the calling number for 800-number calls. Business practices can
vary from region to region.
ANI is available on analog wink-start and digital wink-start trunks.
When ANI is being used, the star key (*) must be used to delimit the ANI digits from the DID/DNIS
digits — that is, *<ANI>*<DID/DNIS>*.
Direct Inward Dial (DID)
Direct Inward Dial (DID) allows extensions on the system, such as users, menus, workgroups, route
points, and so on, to be accessed directly, without the need of an auto-attendant or operator. This is
particularly useful when users on the system want their own telephone number.
DID is available on analog wink-start, digital wink-start, PRI and SIP trunks.
