Porting my Landline from voip provider

Hi all

ported my land line from BT to a SIP provider couple of years ago as I was going to use a VOIP service. 

Now I have VM any time chatter package, How can I port my number from Local phone voip provider to VM?

Thanks

    What you are proposing we would never do.
    We have 3x SIP/VOIP numbers I will never allow them to become trapped in an ISP bundle.

    These bundles, especially with VM are impossible to unpick. 

    If the VM analogue telephone service falls well short of what you have got used to from a real VOIP line, you are stuck.  

    Yes it is an analogue service from the VM Hub, it is an RJ11 socket so you can not use a VOIP phone or an app on a mobile.

    Ask VM to do the port (do not contact your SIP provider), keep the SIP provider's number alive and supply to VM the SIP provider details, like CLI, account holder name, service address and account reference must be exactly correct as even small differences can cause rejection.

    But where do you get this information from? If the losing provider is a landline operator, like BT, VM, Sky, etc, they are well organised, have a unified system and all the information is on their bills, but SIP providers are far less organised (they often have often have a billing database, a service database, a porting database and an upstream carrier database) and are permanently under-resourced (they have 1–2 people handling all ports, support staff who are also doing sales and billing queries and no out-of-hours porting capability at all). So, you've got to do some work to give this port the best chance of working and, as a starting point, look at your bills but call your provider and ask some questions:

    What is the exact CLI format you hold for porting, e.g. 020 8123 4567 (note the spaces).
    What is the exact account name used for porting?
    What is the exact service address you hold for this number in your porting records?
    Who is your upstream underlying carrier? Many SIP providers don't own their number ranges and so lease them, and that carrier’s rules determine whether the port is accepted.
    Do I need a PIN or code to authorise this port and, if so, what is the exact code for porting to Virgin Media?
    Is this number part of any forwarding, hunt group, PBX, or voicemail configuration? If yes then this is a problem as porting is number-only, so ask them to temporarily remove or detach those features and leave the number as a standalone terminating line until the port completes.

    Good luck!

    You can port your number back to VM but do be aware of the limitations of a VM landline.

    On a VM landline, the phone connection is provided from the back of the VM hub via a telephone socket (not a network connection). The telephone socket is designed to take an ordinary domestic telephone connected via an adapter from VM.

    The connection behaves as a conventional telephone wall socket and does not have all the features one might use on a true VOIP connection (as far as the customer is concerned).

    Once you have move the number to VM, it will become part of your VM bundle and VM often makes it very difficult to unbundle the number, should you wish to move it again in the future.

    If the above is what you want, a VM person should be able to assist when they reply to your topic (usually within 4 to 5 days of your first post).
