Features Guide

Allows the pre-assigned extension user to refuse to answer the Intelligent Call Handling (ICH) 
1:1 call on Class of Service basis. The calls which have a specific called party will be 
transferred to an operator. The operator cannot refuse the ICH 1:1 call. This feature is one of 
ISDN's services.

•

The operator cannot set this feature.

•

Setting this feature cancels Call Forwarding or DND.

•

An internal call, Intelligent Call Handling 1:N call cannot be transferred.

•

If the destination extension has DND activated, the DSS button corresponding to it will light 
up red. This indicates to the digital proprietary telephone or DSS console user that the 
destination extension is unavailable.

•

If the operator is not assigned, incoming calls will be transferred to the extension which is 
assigned by Intercept Routing No Answer (IRNA).

•

If the IRNA is not assigned, calls which are not received will be returned to the Integrated 
Services Digital Network. 

•

If this feature is assigned, a dial tone will sound when you go off-hook.

The tone pattern is shown below.

•

There are 2 types of confirmation tone.

Tone 1: When the new setting differs from the previous setting.
