Number Porting Process Guidance
Last Updated March 2015

WHAT IS NUMBER PORTING?

Number porting is a change in the CP (Communications Provider) of a telephone number. Number porting does not change the allocated RH (Range holder) of a number, as the calls will always route through the RH systems.

We use BT IPEX (British Telecom IP Exchange) for all porting requests. BT IPEX have the best SE (Service Establishment) with Range Holders, facilitating the porting of most numbers, particularly from large tier 1 carriers. BT IPEX cannot port a number from a RH that it does not have service establishment with. In any case where BT IPEX do not have SE with a RH, they will attempt to create SE with them, a process that can take around 85 working days, however any errors found on the system they are attempting to create SE for will lengthen this considerably.

For a port request to be accepted by the CNO (Current Network Operator) / Losing CP (LCP) or RH, all of the information on the documents forwarded to the LCP/RH must match what is on file for that telephone number. It is always best to call the Losing CP and ask what is on file when filling out the porting document, and also inform them of your intention to port the number away from them.

WHAT HAPPENS WHEN MY NUMBER PORTS?

When a number ports from an analogue or digital line, the original line is ceased. This means that any and all additional services on the telephone line will also be ceased, e.g broadband. Prefixing on analogue and digital lines (ISDN) from BT happens at the exchange level.

When a number is ported to our service, the original RH changes the prefix on the number, so that it routes out to BT IPEX. It is imported onto the BT IPEX platform and programmed in their core routing engine, which then routes all calls to that number to our platform.

HOW DO I PORT A NUMBER?

In order for Vivid Telecom to port your number onto our platform, we need, for all numbers:

Proof of ownership of the number (in the form of a copy of the latest bill from the current CP)

  1. Authorisation to port from the subscriber (in the form of a GNP Letter of Authority signed by the subscriber)
  2. Relevant telephone number details (in the form of completed porting documents)
  3. Range holder CUPID (find on www.telecom-tariffs.co.uk AND check against Ofcom S1 allocation form)
  4. LCP CUPID (may also be Range holder, otherwise is the company billing you for the number)


We are unable to progress any ports without this information.

WHAT WILL CAUSE DELAYS?

There are a number of factors that can delay ports.

  1. Redcare / security tag exists on the line. You must cancel Redcare or transfer the service to another number before that telephone number can be ported.
  2. The Installation address is incorrect. You must find out the installation address that is on file with the LCP/RH against the number(s) you wish to port for the order to progress.
  3. LCP/RH failure to provide response. You should always inform the LCP/RH of an intention to port.
  4. No SE with LCP/RH. Unfortunately, you can do nothing to affect this.
  5. Incorrectly labelled (single line as multiline etc). You should always confirm the line type with the LCP/RH.
  6. Incorrect telephone details (main billing number, DDI range etc). You should always confirm with the LCP/RH all attached phone numbers, main billing number etc).

EXPORTING NUMBERS

The number porting process is always GCP (Gaining Communications Provider) led. This means that to export numbers, the subscriber follows the import process with another provider and not us. A letter of authority is still required with the new provider and this is checked prior to exports being progressed. Porting guidelines are industry wide so the process will be similar with another CP.

Any number that has been ported into to BTIPEX can be ported out again i.e where we are not the RH range Holder.

Geographic numbers where we are the Range Holder can be exported but there are two caveats to the BTIPEX platform to be aware of, both of which will be negated in the future:

  1. Once number(s) allocated by OfCom to IPEX have been exported away from IPEX, they cannot return to IPEX, importantly this includes any other IPEX Communications Provider.
  2. Number(s) allocated by OfCom to us which are built on BTIPEX can only be prefixed once. This means that the prefix cannot be updated making the move non-changeable until advised by IPEX as above.
  3. Non-Geographic numbers allocated by Ofcom to us and built on BTIPEX cannot currently be exported and is currently out of technical scope.

SINGLE LINE GEOGRAPHIC PORT PROCEDURE

STEP      PROCEDURE

  1. Customer submits to Vivid Telecom:Porting form, Letter of Authority, copy of latest bill.
  2. Vivid Telecom submit to BT IPEX using online portal with CRD (Customer Required Date).
  3. BT IPEX complete an automated look up on their systems, verifying line type and range holder.
  4. If details match records with LCP/RH, order is confirmed.
  5. BT IPEX receive response from LCP/RH confirming acceptance on DD/MM/YYYY@HH:MM
  6. Vivid Telecom notify customer that number has been accepted to port.
  7. At least 24 hours prior to port, Vivid Telecom will add the porting number into the customer’s account ready to receive traffic from BT IP Exchange.
  8. On date and time of port, IP Exchange automatically load number onto ENUM and direct calls from that number to Vivid Telecom so they are ready to catch traffic from RH.
  9. RH automatically applies porting prefix so calls are routed to IP Exchange
  10. Confirmation that number has ported is sent by IP Exchange to us.
  11. Vivid Telecom test-call after receiving completed port notification to make sure calls are routing correctly. If not routing correctly, escalate to BT immediately.

MULTILINE GEOGRAPHIC PORT PROCEDURE

  1. Customer submits to Vivid Telecom:Porting form, Letter of Authority, copy of latest bill.
  2. Vivid Telecom submit request to BT IPEX using online portal.
  3. BT IPEX then apply this information on a NPOR form manually.
  4. NPOR gets sent to BT Openreach, who send it off to the LCP/RH.
  5. LCP/RH then check the details on the NPOR and respond back to Openreach accordingly, if rejected providing reason why.
  6.   Openreach then send the response to BT IPEX.
  7. If accepted, a confirmation response is sent to Vivid Telecom confirming date and time the  porting process will begin
  8. At least 24 hours prior to the port, Vivid Telecom add numbers into customer’s account ready to receive traffic.
  9. On date of port, Vivid Telecom manually configure the number port on IP Exchange portal after the Port Configuration Window Start(s). This loads it onto ENUM.
  10. On date and time of port, Vivid Telecom call IP Exchange, give reference number(s) and/or MBN, and ask them to progress the port, and perform a test-call to make sure ENUM load is correct.
  11. Openreach then progress the port, where the RH applies the porting prefix, and inbound traffic on PSTN should then route through to Vivid Telecom.
  12. If there is down-time of 15 minutes or more Vivid Telecom ring IP Exchange requesting they escalate due to the down-time.

SINGLE LINE NON-GEOGRAPHIC PORT PROCEDURE

  1. Customer has to fill in a separate set of forms – typed, printed on company-headed paper and sent back to us with a copy of a bill from LCP. There must be an account
  2. number for the LCP on forms, address of the Losing Communications Provider, and a bill from them.
  3. If resellers are involved, lead-time stretches – all parties have to be informed of the port.
  4. Once all paperwork is received, Vivid Telecom send off to BT IPEX, who then either send off to the end-user’s LCP (this could be a reseller), or reject because of incorrect paperwork.
  5. BT IPEX, upon acknowledgement of the porting request to the end-user’s provider, then approach the RH with a port order.
  6. Once port order has been accepted, a confirmed date and time for the port to take place will be confirmed to IPEX.
  7. At least 24 hours prior to the port taking place, Vivid Telecom add the number into the end-user’s account ready to catch the traffic
  8. On the date and time of the port, IP Exchange build the number on ENUM, then contact RH to initiate porting prefix.

PORTING PRICELIST

You will notice that many companies not only charge for porting however for each port that fails you have to pay for them. The fees are dependent on the company you are porting to but can be anything from £35 and up.

The positive thing about us is we only charge you for successful ports meaning that we can retry 10 times and you will not be charged a penny.
