Purchase ooma Core VoIP Phone System with No Monthly Phone Service Bills

I just received my Ooma phone system today, and it was simple and easy to setup. Went through the activation of the product and received a phone number and after that got a blue light when I hooked up the Ooma box. The reason behind giving the device 4 stars instead of 5, was one issue, I set up the device the way the instructions stated for consistent call quality (cable modem - ooma - router), on my network I have two slingboxes and use bittorrent software which all require ports to be opened to have full functionality. When I hooked up the Ooma the ports I had opened on my router were now being blocked by the Ooma box. You can go to the following site [...] and access the section to open ports but I still was unable to reach the devices even with the ports enabled in the port forward section. I also tried to put my router in the DMZ(of the Ooma device) and still was unable to get to the devices I opened ports for. I contacted Ooma support(which I didn't have to wait hardly any time, unlike other reviews stating the tech support is miserable) which they escalated my call to second level support that informed me that I will need to plug the Ooma into a port on the router so the ports are not blocked. The downfall of doing this is that the Ooma isn't providing the QOS and when downloading and uploading torrents I noticed my voice breaking up on a voicemail I left on my cell phone. Also setting it up this way the [...]site to access the Ooma was non-functional(even by IP address that the router assigned to the Ooma). I have the DD-WRT firmware on my Linksys WRTG54L router, I will have to setup my QOS and filter the traffic by the mac address of the Ooma device for exempt service(which I was able to get the mac address before plugging the device into one of the router ports). This is not a perfect solution(the reason behind 4 stars) but I guess for free phone service for life I can pause my bittorrent software when I need to use the phone. If you are not requiring any ports to be opened on your network, then this service is perfect and I would recommend.Get more detail about ooma Core VoIP Phone System with No Monthly Phone Service Bills.
