This was purchased to fix a serious broadband outage. I had high hopes as the router seemed to connect to the telco and subsequently performed the duties of a wired and wireless router well and with good speed. However, NO voice is transmitted to landline phones. Carrier Consumer Cellular (technically AT&T under the hood but MUCH superior to customer interaction) is selling a device that WILL offer this service, and other cellular routers are clearly cheaper, so this device isn't for us, although it looks and has been well made a good performance for what it does. (As it turns out, broadband has been restored, so such a device isn't needed just yet.)
