FAQ (Frequently Asked Questions) - Number Porting

(Australia) What are the differences between a CAT A and a CAT C port?

Number(s) porting applications are not instantaneous and have lead times based on the category of the port from the acceptance by the current (losing) service provider:

  • Category A or Simple Porting: 2-10 (up to 15) business days
  • Category C or Complex Porting: 10-35 (up to 90) business days

How do I prepare for the cutover of a number?

In order to reduce the downtime on the day of the port and to allow the use of the number as an outbound callerID, VoIPcloud assigns the number to the customer account as soon as the porting is submitted.

From here, the number needs to be configured on an inbound number block and can also be configured as a callerID on the user objects.

Please remember to do test calls from services not associated with VoIPcloud because trying to do a test call from a device within VoIPcloud will result in false test results.

How much does a number port cost?

The Number Porting fees vary by type and by country. Associated rejection fees are also subject to this variance.

For specific pricing details, please look at the porting form. There is a section on pricing close to the bottom of the form.

How do I deal with a rejected number port?

Please note, that any reference to CAT A or CAT C ports is Australia-specific.

The number of ports is not a certainty. They can be rejected due to various reasons.

In order to get the number ported after it has been rejected, you will need to work with the customer and the losing provider to resolve the reason for the rejection.

Once resolved, you will need to notify the VoIPcloud number porting team through the comments section of the number port. The team will then help you resubmit the porting application upstream.

Please see below for some of the more common reasons for rejections and what you need to do to fix them.

Please note, that while these are the most common reasons for rejection, different
countries will have further specific rejection reasons based on their LNP (Local Number
Portability) codes.

For example, the UK LNP code allows for rejections due to there being security lines associated with the number and where there are no orders raised to cease or transfer these security services.

As always, if you are unsure of what the rejection means and how to deal with it, please check the advice that VoIPcloud LNP has sent back to you with the rejection notice or contact VoIPcloud LNP/support.
