Telecoms companies have so far migrated 16 to 17 million lines from the copper network to digital VoIP, which uses a broadband connection instead, in what is described as the biggest technological upgrade since analogue TV was switched off in the early 2000s.
BT faces criticism for its tactics in pushing customers to make the switch, with some accusing the company of deliberately pausing broadband services to force reluctant households to upgrade. The deadline for completing the migration is the end of January.
The digital landline switch is a major infrastructure project affecting millions of households across the UK. Providers are under pressure to meet the deadline, but the approach has drawn backlash from customers who feel coerced rather than informed.
