Hello

I lose my dial tone after a few hours. Comes back if someone calls but I have to reset my vonage adapter to get the dial tone back.

I took my vonage adapter to a friend's house in STL with Charter Cable Internet and did not have this problem. Could it be my modem? I've tried two different modems here (Motorola and Ambit) and have had the same problem. Here are my details...

1. Your location
Dallas, TX

2. Your ISP name and type (cable, DSL, wireless etc)
Time Warner, Cable

3. Upload and download speeds
Upload 461120, Download 651472

4. Modem make and model
Ambit U10C018

5. Type of Vonage adapter used ie RT31P2 or PAP2
VTA-VD

6. Setup of Network ie Modem---->Vonage Adapter-->PC
Modem & PC plugged into Router and Router goes to Vonage Adapter

7. Issue you are experiencing ie dropped calls, choppy audio etc

there's a high probability it has something to do with your ISP or modem . i would suggest you call timewarner and verify everything.

Try a different Phone and see if that helps.

This certainly sounds like a non-Vonage issue. However, that includes your router as well as the modem and the actual cable service. Start by plugging the VTA directly into the modem overnight. If the problem goes away, then look at the router. If it doesn't, then look first at the modem and then to your ISP. It would also be a good idea to plug your computer directly into the modem and re-run the VoIP test. See if the packet losses and average round trip time go down.

By the way, are the speeds reported by the VoIP test consistent with what your ISP promises? The download speed seems pretty low for cable.

If I plug the VTA directly into the modem, were do I plug the cord that's coming out of my modem?

Right now my modem has 1 Ethernet port. There's a plug going from there to the main "Internet port" on my router. Then my VTA is plugged directly into my port #1 on my router.

My PC is not plugged into anything because I have a Linksys USB wireless setup so my PC doesn't need to be plugged into the router. (By the way, I was having problems before I got the wireless setup).

I appreciate everyone's help. So frustrating. Been going on for 8 months now.

The idea was to run the cable from the modem into the VTA only for one night. That would leave you with no internet service at all for the duration of the test. Just run the one cord from the modem to the VTA. We want to see if you can keep a dial tone for more than a few hours that way. My guess is that you can't, and that the issue is with your modem or the cable service. This test should confirm it.

Gotcha! OK will do but for now I've tried another phone and so far so good. I'll let it go overnight and see if I can keep my dial tone. If it's gone I'll try running it directly from the modem. Appreciate everyone's help!

It appears it was indeed the phone! Just bought a Uniden TRU9485 and I've had a dial tone for 15 hours straight now. (My old phone was a Uniden DX15586). I'm keeping my fingers crossed but I think my problem has been solved. Thanks everyone.
