The 1300/1800 service is, in itself, a call redirection or re-routing system.

When a customer originates a call from their phone (the A-number) to a 1300 or 1800 number (the B-number), they are actually routed (diverted) to your designated phone number (the C-number) which is not displayed to the caller.

Calls can be routed depending on the phone number being called, the location of the caller, and/or the time of day, and can be further re-directed if the destination number is busy or not answering ...

Routing options for Our 1300-1800-numbers.

Our Routing Options are a set of features that offer you the possibility of determining one or more destination numbers based on the location of the caller, the time of the call and the location of your destination number/s.

1300/1800 number routing can be based on the following options of which you (our customer) can choose ONE:

• Origin Dependent Routing
  - Australia Wide Routing (1 area)
  - State Based Routing (8 areas)
  - Region Based Routing (58 areas)
  - Mobile Based Routing (203 areas)
  - Exchange Based Routing (4942 areas)
  
• Time Based Routing
• Call Splaying
• Call Forwarding on Busy/No Answer/Congestion
• Emergency Routing Procedure

Australia-wide Routing - Standard configuration

Routes all fixed wire (landline) and mobile calls to one answering point.
Note that this feature allows mobile calls (prefix 04) to be treated differently to calls from landlines in Australia (eg. barred)

State-based Routing - usually for companies with multiple State offices

Routes fixed wire (landline) calls to one of up to 8 answering points based on the state of origin of the caller and all calls from mobiles to a single answering point.
States are NSW, ACT, Victoria, Tasmania, Queensland, Western Australia, South Australia and Northern Territory

Region-based Routing - usually for companies with multiple regional offices (additional setup fee applies)

Routes fixed wire (landline) calls to one of up to 58 answering points based on the region of origin of the caller and all calls from mobiles to a single answering point.
Examples of regions include Sydney, Wollongong, Newcastle, Gosford

Mobile-based Routing - usually for multiple mobile sales staff (additional setup fee applies)

Routes calls to an answering point based on the geographic area of the caller.
Each of the 203 call collection areas can have two answering points - one for fixed wire calls (landline) originating calls and one for mobile originating calls.
This is the only feature that allows mobile originating calls to be sent to multiple answering points

Exchange-based Routing (additional setup fee applies)

This feature provides customers with a much greater level of detail when selecting their call collection areas.
It allows the customer to define call collection areas based on Telstra's Exchange boundaries where calls are routed to one answering point for each group of one or more Telstra exchange areas as designated by the Customer.
With this feature customers have the ability to route calls from approximately 4900 call collection areas up to a maximum of 1000 answering points.
Note that mobile originating calls can only be routed to a single answering point.

Time-based Routing

This feature allows calls to be redirected depending on the time of day and the day of week.
It can be further combined with the origin dependent routing services to allow calls from different areas to be redirected across the country. *Currently we are not allowing this feature to be combined with exchange based routing.
Each customer can have up to 11 time lists for their office.
A time list covers a single set of 24 hours which is applied to selected days of the week and holidays of the year (both public and business-based).
Each time list can provide time-based diversions for up to seven C-numbers.
A common scenario would have a customer having one set of numbers for weekdays, and another set for weekends and public holidays.

Call Splaying

Calls are routed to different answering points based on a pre-set ratio. Up to 20 numbers can be used. Percentages must equal 100%.
Call splaying can only be combined with Call Forward.
*It cannot be combined with Timed Based or Area Based routing.

Call Forward on Busy, No Answer or Congestion

With this feature if there is a failure to connect to a specified C-number it is possible to re-route the call to another phone number.
This can be done using a timer. If the call is not answered within a specified number of seconds the call is re-routed to an alternative C-number.
A customer may request up to three consecutive forwards for each answering point.

Emergency Routing Plan (ERP) (additional setup fee applies)

Allows a customer to quickly implement an alternative pre-set suite of phone services for their 1300 & 1800 numbers.
This feature can include Origin Dependent and Timed Based routing.
*It cannot include call screening.
A customer may specify up to two ERPs for each 1300 or 1800 number they hold.
