oh yes that's a problem with the flux capacitor on the rear opposite diagonal side of the Vonage device which is corrected by turning it upside down and holding it at a 192 degree angle for 5 hours.
or if that doesn't work, you can post your network setup, devices and model numbers, isp, so on and so forth. a detailed test result (not just the mos number that everyone loves to post) from testyourvoip.com using the boston server is also helpful.

I hope it is okay if I jump in here too. I have the same type of problem. At first it was consistently after about 18-20 minutes into the call (first 2 days of service last week), I would appear to have gone mute to the other party. I can hear them just fine, but suddenly to them I've gone silent. But this weekend, the time is all over the place 8 minutes, 23 minutes, etc into the call. I altered the bandwidth saver to get additional data points as I first thought maybe my ISP was throttling the upload, but that theory doesn't seem to hold water anymore as the times and bytes sent vary so greatly now. I have the RT32P2 (E model) with firmware 1.28.00 and voice 2.0.13 LIVd. I've put it behind another router to monitor the packets, and see they are still being transmitted though to the internet and even when the other party can't hear me anymore, so the adapter/router is still sending out (and I wasn't using the internet connection for anything else at the time so conflicts on my end for the bandwidth) ... but where the packets go after they leave my house could still be a problem) I have plenty of upload bandwidth in the line. (consistently 512 kbps up to several web 100 NDT servers. Also the voice test says the connection can serve more than the 1 one phone line I have). Anyway, we've learned to 'hang up and recall' to continue talking..... Very annoying....

I have Charter cable 5M down (varies greatly between 3-5 depending on source test machine) but 512K up very consistent. Cable has been no problem for over 18 months, however I have only had Vonage for about a week; but if this 'auto mute feachur' keeps up, we may not keep the service.. Other than the 'auto mute' feature, I am very happy. Good sounding voice quality (until I go 'mute'), good features, etc.

here's my "me to boston" numbers:
MOS
4.3 / 5.0
(Best with G.711 is 4.4)

Degradation Sources
Codec 0.57 79.5%
Latency 0.05 6.8%
Packet Discards 0.10 13.6%
Packet Loss 0.00 0.0%
Codec G.711 (PCM at 64kbps,
20ms RTP payload,
80kbps IP BW)
Round-Trip
Latency 211 ms
Packet Discards 0.4%
Packet Loss 0.0%
Loss Periods
Min: 20 ms
Avg: 20 ms
Max: 40 ms
Random Loss
Jitter
Min: 2 ms
Avg: 20 ms
Max: 128 ms

From what I can tell, 0.0% packet loss should be pretty good statistically. Not sure how to interpret the jitter. Could there be a bug someplace in rebuilding the packet buffer when I have a max jitter case and a random lost packet? How should I interpret the packet discards?

Also, here's a web 100 NDT output for other datapoints on the basic internet connection.

I have found that you can improve the situation by setting the Voice Qos Uptream Rate to "Enable" and 512kbp/s in your RT31P2 Adapter. The port can be found in the Gaming section under Qos or after you log in http://192.168.15.1/qos.htm

changing the Qos upstream rate from 256 to 512 was one of the things I tried and it made no noticable improvement as expected. In fact, the first set of calls in that mode we "auto mute" about 8 minutes into the call. Also, lowering the bandwidth saver from highest to mid point actually seemed to make the 'auto mute feachur' happen faster. But then again, that could just be the day. I also experimented with forwarding the specifc ports to the linksys but that made no difference either (when the linksys is beind a netgear WGR614v3 as supposedly the linksys doesn't handle the VPN I need and thus can't be #1 after the modem). So I'm back to 90kps for bandwidth as that gives the best sounding voice ... at least until "they can't hear me any more...."

Well I am having the same issue. No probs at first then this "I cant hear you, you cant hear me" thing appeared. No hardware problems and I have lowered my quality setting. I will search my router for this "auto mute" function.

So is there any explanation for this? I live in Central New York (syracuse). I dont see the need to post all of the information that aboat2 did. unless somebody can explain why they need all that info. I would prefer to give only pertitent information to solving the problem.

Thanks

Sorry if it appears I posted to much, but the webmaster asked for details from testyourvoip.com page as well as network setup, device models, etc. By the way, the router isn't supposed to have a "auto mute feachure" ... that comment was in the same spirit as John's "flux capacitor ... holding at 192 degrees for 5 hours..." comment. But, yes I do indeed have the problem of the call unexpectedly going silent from my end. and it is very frustrating Confused

LOL. I dont think your posting too much. I just think thats alot of info to solve a problem somebody somewhere is getting paid for!

At any rate I still am going to find that 'auto mute' feature!!! LOL

Later
