Features
Direct Dial In (DDI)
n Description
Direct Inward Dialling (DID or DDI) lets outside callers directly dial system extensions. DID saves
time for callers who know the extension number they wish to reach. To place a DID call, the outside
caller dials the number to ring the telephone system extension. For example, DID number 926-5400
can directly dial extension 400. The caller does not have to rely on attendant or secretary call screening
to complete the call.
Note: Direct Inward Dialling requires DDI service from the Network Provider.
In addition to direct dialling of system extensions, DID provides:
DID Dialled Number Translation
Flexible DID Service Compatibility
DID Intercept
DID Camp-On
DID Dialled Number Translation
DID allows different tables for DID number translation. This gives you more flexibility when buying
DID service from telco. If you can't buy the exact block of numbers you need (e.g., 200-499), use the
translation tables to convert the digits received. For example, a translation table could convert digits
500-799 to extension numbers 200-499.
The Aspire system has 2000 DID Translation Table entries that you can allocate among the 20 DID
Translation Tables. There is one translation made in each entry. For a simple installation, you can put
all 2000 entries in the same table. For more flexibility, you can optionally distribute the 2000 entries
among the 20 tables.
In addition to number conversion, each DID Translation Table entry can have a name assigned to it.
When the DID call rings the destination extension, the programmed name displays.
Flexible DID Service Compatibility
You can program the system to be compatible with up to 8 digit DID service. Be sure to program
your system for compatibility with the provided telco service. For example, if the telco sends four
digits, make sure you set up the translation tables to accept the four digits.
DID Camp-On
DID Camp-On sets what happens to DID calls to busy extensions when you have Busy Intercept
disabled (22-11-04). With DID Camp-On enabled, a call to a busy extension camps-on. If Program
22-11-04 is set for No Answer step on, the call will step on after the DID Ring No Answer Time
interval (22-01-06). It will step on to the programmed DID Intercept extension ring group or Voice
Mail (22-11-05/06). Without DID Camp-On, the caller to the busy extension just hears busy tone.
DID Routing Through the VRS
DID calls can optionally route through the VRS. The DID caller hears an initial Automated Attendant
Greeting explaining their dialling options. If the caller misdials, they can hear a second greeting with
additional instructions. For example, the first Automated Attendant Greeting can be, "Thank you for
calling. Please dial the extension number you wish to reach or dial 0 for the operator." If the caller
inadvertently dials an extension that doesn't exist, they could hear, "The extension you dialled is
unavailable. Please dial 0 for assistance or dial # to leave a message so we can call you back."
You assign Automated Attendant greetings (i.e. VRS Messages) to the numbers in each Translation
Table. This provides you with extensive flexibility when determining which greetings the system
should play for which dialled numbers. You could, for example, set up 926 5401 through 926 5449 to
route to extensions 301- 349, and have 926 5450 route to the automated attendant.
