Aloksri,
After you run the test, you should see a button saying Detailed Results..those are the ones I am interested in seeing. It should show latency, packet loss etc. Can you run it again and post the detailed results?

Hello Trowski, I just saw your reply today, so I will post the Detailed results in the evening today. However one new thing I found out over the weekend is that if I dial any 800 or 866 numbers, the call goes through fine without any problems. However with anyother number I get a total silence (even though the other phone rings and the other person can hear me faintly). Not sure if anyone else had anything like this.
I have seen from previous posts that few aread codes many note get connected, but in my case it is just the other way round!

Wow. A lot of people with one way audio. I've been trying to get service up completely for 2 weeks now. It seems that the SLA's with Voip carriers are still too low for me.

Good luck all. Sorry to have to give up. Maybe I'll be back next year.

Ya, lot of people with one way Audio. This forum is my last resort, if it does not work then I probably will fall back on the more reliable world of wired phone lines.

Trowski, here is the result from www.testyourvoip.com when I place a call to Boston:

From what I see, the latency and the media delay might be a bit on the high side...Who is your ISP and what modem do you have?

My ISP is Comcast
My Cable Modem is RCA DCM425 and was brand new, when my service was started 3 months back.

Oh well, finally I could get it to work Lol

. The persistance with contacting Vonage and spending frustating hours waiting on the phone for tech support finally brought success. Basically to summarize this is what happened to get my problem resolved
1) I call Vonage support (4th time in 2 weeks) at around 10pm and navigate through their modified system.
2) After waiting for like 45 mins on phone, I finally got to a CSR. I think now it directly goes to a higher level engineer depending on the options selected.
3) He asked me to describe the problem (again) and then asked to verify the lights on the adapter.
4) He then asked me to reset the router to factory default, but the user Id and password used was undocumented, the userid being user and password starting with tivo*** (dont remember the last 3 chars)
5) Once the router got reset to factory default, he asked me to hold saying that he will do some checks on the background.
6) I wait for like 5 mins and then he asked me to dial the number, which then started working fine and I could dial any number and make outbound calls.

He mentioned that for some reason, my adapter was not sending all the data when making the call and not following the connection protocol properly. The reset with something unknown being done by him in the background did the trick.

So now I will test it out for next few days to make sure it is working fine. The voice quality has imporved and the time before I get the dial tone has reduced to almost negligible.

Thanks Trowski for your help too.

I have also experienced one way audio for about 3 weeks now. I have called Vonage probably 5 times. The first time they said that the adaptor had never downloaded the new firmware, so they pushed that down the line. Then the next couple of calls, they made minor adjustments to my box, but that didn't resolve the problem. The last call, they ran a trace route and said that the fact that I am hopping through 9 different comcast nodes in Boston may be the problem and that I should call them and have them fix that. Can they really changing my routing for me just via a phone call? The first rep I talked with was clueless. I am waiting to hear back from you all before I try again, because it isn't worth sitting on hold for no reason if they can't do anything about it.

Voip test results are below. I don't fully understand what numbers are good and which aren't, so hopefully someone can explain.

My one way audio is only on outgoing calls, and occurs about 98% of the time. I will dial the number, and then hear nothing except for a click when the other end picks up. They will hear me, but I can't hear them. I haven't had a problem to 917 calls, or 818 calls, but 781 and 617 never work.

Thoughts?
