BT has accused its rivals of failing to contribute to the rollout of high-speed broadband in remote areas of the UK.
Earlier this week, a number of UK internet service providers (ISPs) sent a letter to Communications Minister Ed Vaizey complaining about the prices they face to access BT's carrier poles and ducts.
But the telecoms giant has hit back, telling PC Pro that other domestic broadband providers are failing to pull their weight.
The firm explained that it has equipped every telephone exchange in the UK for local loop unbundling, but to date, no rival ISPs have expressed an interest in improving download speeds in the countryside.
"BT is the only company who has installed broadband equipment in exchanges serving the last ten per cent of the UK," the company said.
"So we would question whether these [other] companies are genuinely interested in serving rural Britain given their track record."
BT is currently investing £2.5 billion upgrading its network infrastructure to support fibre broadband services.
