GCI's IMG Failed again for the 2nd time in less than a week, rendering calls from cell to landlines impossible in village.

Call from wifi and it'll result and the call dropping before even connecting. Call from the cell network and you a call "completing" but get an error message

No other carriers work up here, not even roaming, on the cell network. But if you have ATT, TMobile and are on wifi, your calls to McGrath landlines will work.

Why? The IMG is a router that takes the calls and distributes them to where they need to go.... and ATT, etc's central system is not in Anchorage like GCI's is.
