OSAKA -- NTT West Corp. on Tuesday suspended connection services to a company in Fukuoka that allegedly made "wangiri" phone calls in such massive numbers that it threatened to paralyze NTT's telephone networks, NTT West officials said.
The Nippon Telegraph and Telephone Corp. unit said it has cut off services of 10 lines contracted to the company.
It is the first such move since contract revisions were made Aug. 2 empowering NTT firms to suspend service for up to six months to unscrupulous subscribers in cases where they may disrupt phone networks, such as by "deliberately making a massive number of calls" that are intended to go unanswered.
