There are two ways of implementing call forwarding on ISDN2e:
Admin Controlled Call Forwarding
Admin Controlled Call Forwarding (ACCF) is an exchange-controlled call forwarding option. This means that it does not require special equipment. To set up this service, please contact us. The service is active within 24 hours.
Customer Controlled Call Forwarding
Customer Controlled Call Forwarding (CCCF) diverts calls to all numbers to a single number of your choosing. This call-forwarding option is applied by you by programming your equipment to divert the calls. This means it is exchange-independent. Contact your equipment manufacturers if you are unsure whether your equipment supports the service. To enable call forwarding on the line, please contact us.
Note: The forwarded leg of the call is chargeable. The charges appear on your bill along with the subscription for the forwarding service.
The following options are available for both Admin- and Customer-Controlled forwarding:
Call Forwarding Unconditional (CFU)
All incoming calls are immediately forwarded to the nominated destination number.
Call Forwarding on No Reply (CFNR)
All calls are forwarded to the nominated destination number if the call is not answered within approximately 20 seconds.
Call Forwarding on Busy (CFB)
All calls are forwarded to the nominated destination number if the line is engaged.
Note: If you have an ISDN2e line with MSNs present, the call forwarding is configurable on a per MSN basis. This is not possible with admin-provided call forwarding, and also not possible if you are using DDI numbering.
