Migration to DV does not extend your contract, once converted to DV , its up to you if you want to plug a phone into the router , or take advantage of any equipment that BT will supply to integrate your own kit with DV , but obviously if you don’t connect a phone you have a ‘landline’ service you are not using, that your choice.
Some are being offered the opportunity instead of migrating to DV , to remove the landline from broadband using the migration to DV as the trigger , there have been some examples of customers being told that if it’s suitable for them they can simply opt out ( AFAIK this doesn’t extend the contract for broadband ) but if you unilaterally decide that you no longer want a phone service , it’s you changing the terms of the existing contract so a new contract is appropriate.
lit depends if you have been made the offer to drop telephony instead of migrating or not , if you have had the option to drop DV as part of the PSTN switch off it will state it on the DV migration communications / letter / email , what the process is , the appropriate customer service team to advise and if it affects your contract etc , if you have rang the usual customer services yourself , or arbitrarily taken it upon your self to drop telephony ( without the offer )
