Below is the official RFO (Reason For Outage) from Comwave;
Dear Valued Customer,
We wanted to update you on recent toll-free issues you may have experienced.
Comwave uses several backbone networks for Toll-Free, and two weeks ago we added Bell Canada. While balancing traffic, unfortunately, Bell inadvertently left several hundred phone numbers in limbo between networks and without a carrier which ultimately resulted in out-of-service phone numbers. Bell also had issues with toll-free origination from the United States. As of Friday afternoon, we have reinstated all toll-free numbers back to the original Comwave network and have halted all further plans with Bell until further notice. After a decade of reliable toll-free service that has never given us a reason for second thought with our core network, we are not impressed with Bell.
Should a change be contemplated in the future, we will be consulting with you.
We understand how important phone numbers are to the businesses you support. Please accept our sincere apologies and let us know if we can help further.
