Direct Inward Dialing (DID)

Release 6.0 and Later

Use this feature to have Direct Inward Dialing (DID) numbers on a T1 line routed automatically to
the PARTNER extensions, hunt groups, or calling groups you specify. When a Direct Inward
Dialing (DID) call arrives, the PARTNER system "collects" the digits from the T1 service provider
(that is, the number that was dialed) and matches the number to a DID Mapping Table you
created. If the incoming number matches an entry in the DID Mapping table, the call rings at the
matching extension or hunt group.
To use this feature, you must:
purchase a "block" of Direct Inward Dialing (DID) telephone numbers from your T1 service
provider
use PARTNER ACS R6.0 PC Administration to map extensions, hunt groups, or calling groups
to the Direct Inward Dialing (DID) telephone numbers
See the PARTNER ACS R6.0 PC Administration online help for more information.
Outgoing calls can be made on T1 lines administered for Direct Inward Dialing (DID).

Considerations

Dialing (DID) on T1 lines.
You can have a call on a T1 line with Direct Inward Dialing (DID) ring at an extension that

Group contains T1 lines with Direct Inward Dialing (DID), callers will receive busy signal
