You will have to get into the programming mode and change Memory Block 4-01 for the port of each phone you want to ring. The corresponding light for the button is OFF for no ring, GREEN for ringing, and RED for delayed ringing.

I have the same problem for this hpone. The phone can answer and make call but not ring, of couse the answer machine function does not work. I used Rogers home phone and now the Linksys voip adaptor. But the phone works well with landline. I think the ring votage may not enough to ring the phone. Anyone get the solution?

I just bought a new Uniden DECT 6.0 phone and had a similar problem. It wouldn't ring when plugged into my Linksys voip router, but my old 5.8 GHz did ring. It would get a dialtone and make calls, but when called via an outside line, it would appear as if it was ringing. If I picked up during this "silent ring," it would answer and take the call. It wasn't a ringer volume issue. I called tech support, they said on the main headset, unplug the battery, then unplug power from the base, then unplug the phone cord from the base. Wait 15-30s. Plug the phone cord, then power, then reinstall the battery. Press the End button on the phone. Put the phone on the base for 15-30s. Pick up the phone. Press and hold the Find button on the base. Do this Find thing 3 times. Put the phone back on the base. Wait 10-15 minutes. Then try calling it to see if it rings. Worked for me, finally got it to ring before I decided to return it.

Your ISP connection speed may be inadequate. Typically, the upload speed (outgoing voice) is much slower than the incoming speed. To check majicjack recommends that you test your system on http://www.speakeasy.net/speedtest/ .
It's also possible that your internet provider is purposely delaying the outgoing latency in order to discourage VoIP that THEY don't provide. I think this is (or at least should be illegal) but in any case a complaint to the FCC might be in order.
