Incoming calls do not complete-end up in voicemail

I've been trying to get this resolved via vonage support for nearly a month now.

Most incoming calls (not all) call in, get 2 rings on the vonage side and we pickup and hear nothing, dead air. On the calling side they hear 3 rings (pretty consistent) and then goes directly to voice mail.

Sometimes incoming calls work fine, seems to be 1 out of 3 or 4 on average. There seems to be no correlation between where the call is coming from or time.

My current setup is Time Warner cable, 5mbit down and around 700kbit up.

RTP300

NAT router is a linux box running IPTables, traffic shaping has traffic on all vonage related ports getting highest priority. None of the vonage related ports are being blocked.

No packets either to the adapter or from any of the vonage IP's or ports are being dropped (all drops logged to syslog).

This problem started in december (not sure exactly when, we don't get all that many calls), and so far no luck fixing it. I've been through 5 or six 'updates' to my RTP300, another one pending until I get home to disconnect/reconnect.

What really bothers me about this is why is this taking so long to fix? There is obviously a problem, there is presumably a solution. I'm currently capturing all traffic to the RTP300 so I can perhaps figure it out for myself.

Anybody else experience this? Suggestions?

When you log into your Vonage 0n-line account and click Features>Voicemail Settings (configure), how many seconds do you have configured before the call is sent to voicemail?

If it is not enough, you might want to increase it.

I have mine set to 30 seconds and that seems to give me enough time to answer and it gives my answering machine enough time to pick-up.

Probably should have mentioned, been there Wink

. It was at 40 seconds, I changed it to 50 seconds with no change in the symptom. I would think that a 10 second increase would have made some noticeable difference (at least one more ring on the calling side perhaps).

Thanks for the idea Wink

Check the values in your Call Forwarding. It sounds like your calls are being snatched away from you even though you are answering.

This will, also, forward your calls to voicemail if not answered in time.

Oh yeah, I'd be happy to post the results from the voip-speed-test but this site is using NukeSentinal which apparently decided to block me because I browsed here using Lynx (text based browser). Hopefully they'll get that straightened out..

I'm pretty sure it's not my ISP though, I've got plenty of speed and it's been very reliable.

That was the Call Forwarding that is configured in your Features section of you Vonage on-line account.

Currently my call forwarding is disabled, website says will forward to voice mail in 50 seconds.

Considering the time it takes from dialing to voice mail (even though the vonage side picks up after 2 rings) is somewhere in the neighborhood of 15-20 seconds, if it's 'timing out' there's a problem on their end for sure.

That one IS a head-scratcher. Good luck in getting it resolved.

Yikes, I was hoping for some help here Wink

....

I guess I'm also hoping to find out if anyone else is having this problem. I wouldn't be surprised if it was time warner (they have their own more $$$ Voip), but if that was the case I'd expect it to happen all the time.

Latest from Vonage customer service, they've move the line to the other phone port on the adapter. I'll move it tonight and see what happens...

Now this is interesting, when I connect the RTP300 directly to my cable modem (powered down of course, for about 1-2 minutes). When I power on the power light lights (of course) and the Internet light blinks, and continues to blink... I left it that way for 5 minutes and it never properly hooked up. When I connect it back up to my switch it works (as much as it does).

I checked was to make sure it was using DHCP, and it is (and was). This is rather interesting, almost wonder if Time Warner is detecting a competitors product and blocking it. Hookup up to the switch and through my firewall would of course not allow them to see the RTP300.
