In what took 6 days to resolve turned out to be Rogers Internet blocking certain VOIP traffic to certain IP ranges.
This was not a complete blockage of VOIP which makes it really difficult to detect. Rogers was blocking certain voip traffic from a specific carrier. Voip service worked just fine from another carrier.
This was not a home setup that was running peer to peer software constantly. This was a business account that uses voip, encrypted traffic for a financial application, and encrypted traffic of online backup data.
This makes me believe that Rogers does employ software to automatically detect peer to peer traffic (even on business service) and throttle/shape/block suspicious activity. In this case I believe the software was fooled and started blocking legit voip service.
Thank you Roger! I love you as much as Bell now!
