One month in and so far we have no problems to report. We have the Basic Line package, a no-frills phone with no features, not even Caller ID or voice mail. No issues with service or quality. The few times the power has gone out, the cable modem switched to the built-in back-up battery and phone service continued without interruption.
The only problem we had was when Jeremy unplugged the cable modem to recharge his Nintendo DS. A quick lesson with Jeremy resolved that issue.
Based on our average monthly Bell Canada bill, we will save at least $1,440 over the next 24 months. That is a nice chunk of change.
