An unexplained network fault causing a lack of dial tone on landlines has hit TalkTalk consumer and business customers.
However, in spite of a number of customers taking to social media to report they were unable to place any calls as a result of the problem, TalkTalk said this was not necessarily the case.
“We’re experiencing problems with no dial tones on some landlines. If you're affected by this, you may still be able to make or receive calls,” the company said in a statement.
Other customers reported lengthy waiting times on TalkTalk’s customer service helplines to report the issue. TalkTalk acknowledged high call volumes, and advised customers to register for text updates on the situation.
“We're working hard to fix this issue and will provide a further update here by 2:00pm today,” said the operator.
This is the second major fault to affect landline calls in the UK this week.
Earlier this week customers of EE and O2’s mobile networks were affected by a fault that left users unable to place calls out to landlines.
The sustained outage occurred on the afternoon of Monday 11 January 2016, with a number of customers saying that they had completely lost their network signal.
O2 blamed the problem on an issue with BT’s network, although BT reported it was unable to find any fault.
Update: As of 2:00pm on 14 January, TalkTalk said that the fault had been resolved for the majority of customers, and it hoped to have any remaining issues fixed by the end of the working day.
