Telus has vowed to investigate a total failure of Calgary's 9-1-1 service early Monday morning.
"We're not going to leave any stone unturned," said Chris Gerritsen of Telus, "until we find out what's gone wrong, and fix it, and make sure it doesn't happen again."
Gerritsen said Telus accepts responsibility for the 30-minute breakdown that left 37 calls unanswered.
Fortunately, no critical emergencies were unattended and Gerritsen said the public shouldn't be concerned.
"The 9-1-1 service is a reliable service and it's been reliable for many, many years, Gerritsen said.
While Telus crews work to sort out what went wrong, so are experts from the city.
"I'm not as satisfied as I'd like to be," said Ald. Ric Mciver. "But the good thing is there's no denial and we have assurance everybody's working hard on it. So today, that's as good as it gets."
McIver said it will take at least three days, and perhaps as long as three weeks to track down what caused the failure. Meantime, the system is operating normally and the city says anyone who calls will get an immediate response from police or EMS.
