   Our network team has routed around the problem in Whitehorse. Calls there that rely on the call signalling network should work. We are looking at alternate routing for Yellowknife as well. --- Notre équipe réseau a contourné le problème à Whitehorse. Les appels qui dépendent du réseau de signalisation d'appels dans ce secteur devraient fonctionner. Nous examinons aussi un acheminement de rechange pour Yellowknife.
