We've connected to a business phone service company thru our home internet connection using a Mitel VOIP phone very reliably for some years. Allows my wife to work from anywhere we can get an internet connection. But suddenly just a couple months ago, Comcast rolled out this Speedboost, bumping our service speed up alot , but it seems they also introduced alot of buffering and lag, which is causing the phone system to occasionally lose partial connection - usually the other person can still hear my wife, but she can't hear them, so the download (which reads over 85Mbps) seems to be the problem. In doing some testing, we seem to be getting dupack problems, and packets out of order, leading to a very poor quality of service rating for the connection. In checking with other people at her work, it seems there have been alot of similar reports, also all on Comcast. Comcast replaced all the cable ends, splitter, we replaced modem (twice), router, ethernet cables, and tried 2 different phones - same intermittent problem. Does anyone know if switching to Comcast business will resolve this, or is there a way to "downgrade' to the old, slower but much higher quality service, or any other suggestion? Multiple calls to service, and it seems Comcast can't help (most don't seem to understand) so maybe someone on the board here? Help!
