Andy Abramson says Verizon is blocking VoIP on its FiOS fiber-to-the-home service. He apparently got a heads up from an AT&T user who said that his ActionTec router that “connects to the FIOS Coax won’t allow him to use AT&T’s CallVantage.” On the DSLReports forums, there have been some problems reported as well. We decided to check in with Verizon and ask them what’s the real story.

Their spokesperson emailed us back with this response: “There is no blocking of VOIP over FiOS. We have not been aware of any widespread problem like the one described. We want FiOS to work flawlessly for our customers, and this specific problem is being investigated. In all likelihood this is some specific equipment issue with the compatibility between routers involved here. “

It would have been great to know the router model number that is causing problems, because Actiontec is a Verizon-approved router vendor. If you are experiencing some problems, let us know. If not, then which service you are using and how is the performance so far?

    Vonage has been working without any trouble at my house for the last two years with Verizon FIOS

    I’ve had FIOS working with another VOIP provider just fine since day one. I also use the actiontec router mentioned. So it doesn’t seem to be a general problem.

    I just got Fios 2 weeks ago with the Actiontec MI424WR and I can confirm similar VoIP problems. I connect to my corporate voice pbx and since the switch we have had little or no service when running through the Actiontec. Interestingly, when we change the configuration to act as a bridge to our linksys router, everything runs fine.

    In troubleshooting the Actiontec, we encountered several SIP errors in the log. We chose not troubleshoot it since we didn’t want to deal with an unresponsive tech support. I’d love to be in touch with your verizon contacts and sort this out.

  4. My voip works fine with the actiontec router, however, other machines of mine do not work well with my actiontec because it’s a crappy router. I don’t think it handles DHCP timeouts very well – you’re much better off manually assigning ip addresses. You should of course assign ip addresses manually if you’re going to use the firewall.

  5. My Vonage voip on the high-speed FIOS option works better than any cell phone connection I’ve ever had, crisp & clear. Very close to copper based analogue. Six months, no problems. Superb service on minor adjustments. NJ. I do have a Vonage complaint: paying for unlimited dialing to the EU, but can NEVER get through.

  6. Works great for me … I only have FiOS Data 20Down/5Up and no phone service from verizon.

    Router is Actiontec MI-424WR.
    LinkSys PAP-2 NA

    Using Voipdiscount for outgoing calls
    Using GalaxyVoice for incoming calls

    (Stanaphone and Messagenet (Italian provider) both working great)

    Working great for almost a year.
    What was reported here is very likely a user generated problem.

  7. … To Eric Mandel, setting up two routers in cascade is not the easiest of tasks, and most home routers are not even built to do that efficiently this is why everything works when you have it in switched mode.

    As a possible solution, you might be running behind a double NAT in your configuration. You should disable NAT in one of the routers and enable RIP on both. This should get your setup to work. By the way, there is nothing wrong with the bridged configuration that you are using.

  8. … to Ed Huang, I agree that the DHCP is bad in the actiontec. I really do not know why they did not fix that yet. The problem is very simple, if a DHCP lease time expires since a coputer does not log in for long time, the next time the same MAC address tries to get an address the DHCP will not work.

    It is possible that this might be a workaround for some of the other pieces a.k.a. STB which might not work correctly. a.k.a. having the wrong MAC address during boot-strap. (Only guessing here)

    Another Net Neutrality Red Herring. Listen people. There is no conspiracy against you other than to get the most money out of your pocket. Taking a technology away from people is not the way to do that. As long as there is competition, companies cannot do whatever they want, or they will lose customers. I can’t wait to get FIOS, but if they want to block VOIP, then I’ll stick with cable. Or DSL. Or Satellite. Or WiFi. Or dial-up. There are plenty of companies out there who want my money and who can provide the service I want.

    Plenty lf FiOS users use OTT VoIP over FiOS. “Smith on VoIP” confirmed this by placing test calls over FiOS to Vonage, Sunrocket, & Skype . . . see http://www.smithonvoip.com/voip-commentary/vonage-works-fine-over-verizon-fios/
