That is a little erronious but understandable. Phone providers are required by law to have 911 service and connect to the regional 911 center. Anchorage has 2 dispatch centers (APD/AFD) and APD always answers first. UAA has a center that gets all 911 calls for landlines at the campus, but not cell calls. ASD does not have a 911 center itself.
The state does not operate a single state-wide center either. In Mat-Su AST is dispatched by Wasilla Police which has a center, and Palmer Police have their own with Fire/EMS for the Borough. Fairbanks has a city center, a University center, and an AST center. Kenai has a joint center.

These come from various funding sources, and it's also important to remember that building a consolidated center is very expensive, on the order of millions of dollars. Mat-Su has looked at this for years, but there simply is no money (and no agreement) on how to make it a reality.
