Call Forwarding
Customers can control their Optus Direct Line (PSTN) service to automatically forward incoming calls to an alternate telephone number using a simple set of keystrokes from their telephone handset. Call forwarding can be set up under three options:
- All incoming calls forwarded;
- Incoming calls are forwarded if the line is busy;
- Incoming calls are forwarded if not answered within approximately 12 seconds.
Each call forwarding request (like call forward on busy) has a specific code that informs the network what to do. Please refer below for the list of call forward codes.
Unconditional (all) call forward:91
Busy call forward:92
No Reply (rings out) call forward:93
To activate a particular call forward (press from your handset): * (code) (phone number to divert to) #
To cancel a particular call forward (press from your handset): # (code) #
Call forwarding is not available on Optus Direct Line (PSTN) services that are configured as part of a hunt group or on services with voicemail activated or on handsets that are connected via a PABX or key system.
Call Number Display
You can choose to present or restrict Call Number Display (CND) for each call. Direct Line (PSTN) services that are configured as a hunt group will send the Primary number within the hunt group if CND is activated. You can override your choice on a call by call basis by dialling an override code in front of the dialled number as follows:
- Restrict CND: Dial 1831 in front of the dialled number
- Present CND: Dial 1832 in front of the dialled number
Voicemail
A voicemail facility is available with Direct Line (PSTN). Optus Direct Line (PSTN) voicemail works like a personal answering service for your business. Voicemail is not available on Direct Line (PSTN) services that have line hunt or call forwarding active. Up to 40 messages can be stored; unplayed messages may be kept for 28 days and played messages may be kept for a further 10 days.
