Calls cutting out

Posts: 7 · New Forum Member Joined: Jan 06, 2007 Posts: 7

Everyone I talk to complains that my calls keep cutting in and out. I have ripped apart my home network thinking that it was an interference issue. Im now down to my Vonage router (RTP300) my cable modem (Comcast) and a corded phone with no change. Ive adjusted the bandwith saver setting to its minimum setting and now Im out of ideas. Any suggestions would be helpful.

is this on incoming & outgoing calls?
by cutting out do you mean the people you are talking to hear your voice randomly dropping out?
is it only your voice that is dropping out, or is it the people you are talking to also?

as Steve has suggested, if you run the Voip speed tests on this website and also on testyourvoip.com with a test call to Boston, we should get better information on possible suspects.

I would run both once with your current setup, then run them again with your computer connected directly to your modem.

If there are/are not significant differences in results, it should point the finger somewhere.

Hi,

I've had Vonage since nearly the inception. With rarely an issue. Last fall I added another line to the service. Now and again during the day while using the second line, the volume of the person I am speaking with drops considerably - they can hear me but I can not hear them - so much so that I have to call them back on another line...usually my mobile.

Here is what I have: A Toshiba PCX2500 Cable Modem, with the Vonage supplied Motorola VT1005V Voice box. The cat5 is connected directly to the voice box, then from the voice box to the D-Link router. So I shouldn't have a firewall issue, nor a router issue as the router is after the voice box. This is the way Vonage had me set the system up when I phoned to report this issue. Previously the wiring was from the modem, to router then to the voice box. My issue has happened both ways.

I have run the speed test provided on this site, which is pretty nice. It says my call quality is in the 90% range one time and 53% another. Obviously the line is not consistent. Download Speed is 2.6mmbps (T2 speed)and upload is 435kbps (satellite speed). The system also says I should be able to support 4 lines...well - it seems to me 2 lines is too much. When I get these drops in volume, I am in the house alone - it's just me and 2 pc's. Are cable is Comcast...

Any suggestions would be appreciated! And sorry if this issue has been covered many times - but I could not find it anywhere.

Thanks-

BJ

MP6365, we really need the detailed results of the tests. Look on the advanced tab for the forum test. You can copy and paste on the testyourvoip site.

Bj021, you'll get better response if you'll start a new thread. Give us all the technical details listed in the sticky message at the top of the forum. Include the technical details and tell us more about this volume drop. Is it accompanied by distortion, noise, or anything like that?

I am also experiencing the identical problem with choppy audio. I am also in Baltimore using Comcast. I'll be curious to see what additional posts will be added on this topic.
