A company is promising to cut landline phone service costs to consumers in Whitehorse, Yellowknife and Inuvik, N.W.T.

Iristel claims to offer local phone service at half the cost while allowing customers to keep their phone numbers.

The company says it uses VoIP, an internet-based phone service.

This is the latest change since the Canada Radio and Telecommunications Commission ended NorthwesTel’s monopoly on telecommunications in the North last year.
