Feature interactions
Digital Trunk Interface (DTI) – Commonwealth of Independent
States (CIS)
The construction of an ANI message does not care if Incoming Digit
Conversion is used. The DN sent as ANI is the actual DN of the set, not
necessarily the Direct Inward Dialing (DID) number to dial to reach the set.
Therefore, if an external party uses a DN, delivered in an ANI message, for
making a call to the corresponding extension, the call may fail.
EuroISDN Continuation
The Incoming Digit Conversion Enhancement (IDC) feature converts
incoming digits from a DID route. This feature is supported on the incoming
EuroISDN DID routes. Digits received as a called party number are converted
if the IDC feature is activated on the route. Digit analysis is then performed
on the converted digits by the Meridian 1.
EuroISDN Trunk - Network Side
This feature is supported on the incoming EuroISDN Trunk - Network Side
connectivity DID routes. If IDC is equipped, digits received as a called party
number are converted, and digit analysis is then performed on the converted
digits.
Three Wire Analog Trunk – Commonwealth of Independent States
(CIS)
The construction of an ANI message does not care if Incoming Digit
Conversion is used. The DN sent as ANI is the actual DN of the set, not
necessarily the DID number to dial to reach the set. Therefore, if an external
party uses a DN for making a call to the corresponding extension which is
delivered in an ANI message, the call may fail.
