I had T-Mo @Home until the TA hardware died, at which point t-mo upgraded me to a Linelink. The Linelink is smaller, consumes less power, is easier to setup, and ultimately is a piece of garbage.
I have several reasons. First and foremost, the Linelink stops working randomly. Never during a call, but at some point while idle it loses the connection to T-Mo and cannot place or receive a call. There is no warning - I still get dialtone and the indicator LEDs on the linelink look normal. This happens randomly but regularly - sometimes after a few hours, sometimes after a couple of days. Please don't tell me it's my ISP, my router, the color of the moon, or some other lame excuse unless you can provide solid technical reasons. And on the subject of a network-related issue, I have used the linelink with two different ISPs (Cox and CenturyLink) and two different routers (a Mikrotik RB750GL with Cox AND CL, and a Zyxel C3000Z with CL). It has exhibited this problem with both providers and both routers.
The next problem is with the voicemail. I have an answering machine and would prefer to use it rather than T-Mo’s voicemail. But even with the T-Mo voicemail completely deleted (according to customer service), a caller will still get the T-Mo voicemail if the Linelink is “crashed” or if a call is in progress and the person on the call does not respond to call waiting in time. Since voicemail is “disabled” I have to way to check these messages. Problem number three is call waiting. I have called T-Mo support time after time complaining about this, and they have set the call waiting delay to the longest they can, so they say. When a second call beeps in, I have to respond *before* the second beep or it will go to t-mo voicemail. That’s a couple of seconds from first beep to lost call - not even enough time to excuse myself politely from the first conversation.
T-Mo - I *require* one of two answers from you. Either that these issues will be fixed ASAP, or that they they will never be fixed and I should find another provider for my land line.
