Thanks for choosing to port your phone number to Cerberus.  

As part of your number port to Cerberus we offer you the chance to perform a “pre-port test call”. This is an optional check to make sure that things are setup correctly before your port happens. It is not mandatory.  

If we have given you a date for your port to happen then the port will go ahead on that date even if you don’t bother with the test call. However, we recommend that you do use this free facility to help minimize the chance of problems when the port completes. 

The pre-port test call is a test call that happens before the port to the new solution so you can check: 

  • That your product is set up correctly 

  • Identify any potential faults before your number goes live 

  • Check call quality 

  • Check call routing 

The process enables you to check that the infrastructure in place at the customer environment is correctly configured and capable of supporting the porting numbers as required. It also provides you with peace of mind in the days and weeks leading up to port completion and allows you to give confidence and reassurance to your end customer that a smooth transition will be achieved. If there is a problem, then the test call will help you troubleshoot this and hopefully get it working before the port completes.  

You’ll receive an email from Cerberus when your numbers are ready to test. If you perform the test calls before you receive this email, then the test call will fail and it will break out to the existing phone service like a normal call. 

In order to make full and proper use of this test facility: 

If you are a MyCloud Voice customer you will need to configure your equipment (ATA, VoIP handset, softclient) to use the MyCloud Voice service for incoming and outgoing calls. 

If you are a Horizon or MyCloud PBX customer we recommend that you configure a test call plan for at least one of the porting numbers in each DDI range before triggering the test call. For port orders where the losing provider is anyone other than BT, we advise that you complete a test call for every porting DDI, or if the number range is extremely large, then a random sample thereof. 

We recommend that you have completed your pre-port test call by the day before the number is scheduled to port.  

To use the facility, you simply have to: 

  1. Call 03330 146 146 using a phone other than the one on the service you are testing, for instance a mobile phone. 

  1. Enter the porting prefix (on the confirmation email) using the keypad on the phone you are using to make the test call. 

  1. Enter the telephone number you want to test using the keypad on the phone you are using to make the test call. 

  1. Press # on the keypad on the phone you are using to make the test call. 

This will generate a test call to your new service. You should find that the call is routed in the same way that it would after the number port. If you are a MyCloud Voice customer this means that the phone on your ATA, VoIP handset or your softclient will ring, and if you answer that call both parties should be able to speak to each other.  

If you are a Horizon or MyCloud PBX customer then the call should be routed according to the dialing plan setup.  

You can use the test facility as many times as you like.  

If you find that the pre-port test call fails then please get in touch with the Cerberus Support team on 0345 257 1335 , or via email at support@cerberusnetworks.co.uk
