Numbers can in most cases be ported in to one of essensys voice providers.

To proceed with a port request, a ‘Letter of Authority’ needs to be completed, printed on a client's headed paper and signed by the client. The Letter of Authority is an industry standard form which contains the Losing Communications Provider (Occupier's current provider) and the Gaining Communications Provider (essensys provider). The Occupier will need to know their own provider and telephony set up to complete this form. We also ask for a copy of the full phone bill showing the address phone number and company name to ensure the details match.

Blank Letter of Authority can be found here. This is included to provide an example only as we must use the correct carrier form. This must be completed in full and printed on the client's headed paper. Once completed, you can send to service.delivery@essensys.tech.

You should also confirm at this time if any of the numbers will be used as a Main Number by the client, and if any other numbers on the client account should be removed following successful porting.

Once we have submitted the request, we should receive acceptance or rejection of the number porting order by the Losing Communications Provider within 10 working days. If it is a straight-forward port, the standard lead time is 19 working days, but thy can often take longer.

Once we have the porting accepted, we shall add the DDI(s) to essensys Platfom.

essensys will add a note to the case, advising that the numbers need to be activated on the essensys Platform and will provide a link to an article which will assist with this, in case you're unsure. It is crucial that this step is completed, or the numbers will not work once ported.

The number should cease with the Losing Provider on the day it ports over. If it is the only number on the account, the account should also cease. This does not always happen; therefore, we recommend the client contacts their provider to ensure their billing and account is correctly ceased AFTER the porting has taken place.

Please also note that if the client cancels their account before the number is ported over, then this could cause the porting to fail. If the client is tied into a fixed term contract with their current provider which goes beyond the porting date then they may be liable to pay a cancellation fee equivalent to the total amount of monthly charges to the end of their contract term.

Only clients who port numbers in to essensys can port them out.

All DDI’s assigned by essensys are part of a large DDI Block range assigned to an Operator and a Building. As these DDI’s are part of a large block range, they cannot be broken down into smaller ranges or single individual numbers to be ported away. This fractures the DDI Range, so is not allowed.

For clients who can port out their numbers, the process is led by the Gaining Provider. The client will sign a Letter of Authority and provide this to their new provider. The client may ask for details of their numbers, such as whom the Losing Communications Provider is, What address the numbers are registered to, and what the full DDI Range may be.

Once the client’s new provider has submitted the port request to the carrier, essensys will receive a “Leaving Notification”. This will detail the phone number(s) requested to leave, and the date/time they are requested to leave. essensys will issue this notification to the Operator to notify the numbers will be leaving. Operators will need to issue notification to the End-User to notify the numbers will be leaving, and give them an opportunity to reject the order if the port request is deemed unauthorised.
