Porting with an ​Exchanged Based Diversion (EBD) - What's involved?

What is an EBD?

Exchange-Based Diversion (EBD) is a process where a service number is converted into a virtual number at the carrier level. This removes all associated complexities from the number — such as line hunts, Telstra DOT features, or other legacy configurations — allowing the number to be diverted cleanly at the exchange.

Once applied, the number can be ported as a Category A (simple) port.

Prerequisites

Before requesting an EBD, the following conditions must be met:

1. DIDs must be active and portable.
2. The numbers must not be in an active porting process.
3. Temporary DIDs (Temp DIDs) must be available for diversion.

How many Temp DIDs are required?

• If routing does not matter:
  • Only one Temp DID is required to divert all numbers.
• If each DID must be routed individually during the EBD period:
  • You must allocate Temp DIDs equal to the number of porting DIDs.
  • Example: If you are porting 3 numbers, you will need 3 Temp DIDs.

EBD Request Process (Telstra)

1. The account holder contacts Telstra and requests to be connected with the Telstra LNP (Local Number Provisioning) team to discuss porting their numbers out.
2. The account holder must confirm the numbers are active and portable.
   • If they are not active, request that Telstra reactivate the numbers and make them portable.
3. The account holder requests EBD (Post-Paid) and provides the required Temp DIDs for exchange-level diversion.
   • Note: EBD must be Post-Paid for the numbers to remain portable.
4. Telstra applies the EBD. This usually takes 1–3 business days.
   • Important: Once applied, all existing call forwards will be removed.
5. After the EBD has taken effect, you can request Aatrox Communications to submit the DIDs in a PAF as a Category A port.
   • Standard CAT A porting timeframe: 6–10 business days from acceptance.
