ISDN User Services Guides – What Features Can I Have On My ISDN Service

Call forward

What is call forward? Call forward allows you to forward calls to your ISDN service to another number.

There are three types of call forward:

(a) call forward immediate forwards all calls to your ISDN service to another number; and

(b) call forward busy forwards calls to your ISDN service to another number when your ISDN service is busy; and

(c) call forward no answer forwards calls to your ISDN service to another number when your ISDN service does not answer.

There are two ways call forward can work:
(a) fixed (you tell us the number you forward to and we set it at the exchange);and

(b) variable (you set the number you forward to yourself)

You can apply call forward to individual numbers on a Multiple Number service,and to the group directory number on a Direct Indial service. In the basic form of the feature for Direct Indial services, call forwarding is applied to the entire indial number range and calls are forwarded to a single, common number. If call forwarding is needed at the extension level, call deflection or private network partial rerouting is needed (see below).

Call deflection is a feature similar to call forward which allows you to deflect a call to your ISDN service to another number rather than answer it. The method of entering the number to divert to will depend on your handset, but typically you will be required to pre-program it in your equipment. You can deflect calls received at individual extensions in a number range, without affecting the rest of the number range. Call deflection is provided on a per number basis when used in conjunction with the Multiple Number feature. When this feature is provided on Direct Indial services, it is available to all extensions, subject to allowances within your terminal equipment. The control procedures for this feature depend on your equipment.Please refer to your equipment user guide.

Private network partial rerouting allows you to manage call forward and call deflection using your equipment. This allows the call forwarding and deflection to be applied to an individual extension of an indial range rather than to the entire number range. It allows for diversion of calls within your equipment or private network, or back to our network from your equipment. Private network partial rerouting provides for network-based diversion, which means that the information/B channels are released and can be used to handle other calls.

Call forward (variable) is a standard feature available on the ISDN 2 Enhanced service. Call Forward is available as an optional feature on all other ISDN services except ISDN 2service with Direct Indial and point-to-multipoint.

Call forward (fixed) and call deflection are available as optional features on all ISDN services except ISDN 2 service with Direct Indial and point-to-multipoint.

Call Deflection is not available via the analogue ports on ISDN 2 Enhanced. You can get call deflection for ISDN 2 with Multiple Number and Line Hunt services, and as part of the call forward (all conditions) feature on ISDN 2 service with Direct Indial and point-to-point and ISDN 10/20/30.

You can only get private network partial rerouting if you have an ISDN 2 service with Direct Indial and point-to-point or an ISDN 10/20/30.

There is no charge for call forward, call deflection or private network partial rerouting features. We charge you at standard ISDN call rates for forwarded calls.

Enquiry/Conference

What is Enquiry/Conference? Enquiry/Conference lets you place a call on hold, make a second call or accept a call waiting call, and join the two calls in a three-way conference call.

Enquiry/Conference is available as an optional feature on the following ISDN services:

(a) ISDN 2 with Multiple Number service; and
(b) ISDN 2 Enhanced.
It is not available on ISDN 2 with Direct Indial or ISDN 10/20/30.

There is a monthly for Enquiry/Conference (in addition to the standard monthly access charges for your ISDN service). In addition we charge you our standard ISDN call rates for calls you make.
