I am getting outbound fast busy on numerous calls to numerous numbers. I did a test to Boston from testyourvoip.com and here is what I get:

You have a lot of packet discards. Do you get similar results if you eliminate the router and plug your computer directly into the modem?

What kind of phone are you using? A 2.4 GHz cordless phone will interfere with your wireless router.

Yes, I am using a 2.4gHz phone. I believe I have a 900mHz laying around here somewhere. Think it will interfere with the other 900mHz sitting on this same desk? Smile

Typically fast busies meant the telco couldn't get a trunk line to complete your call. If the numbers you're dialing are not other Vonage/VoIP numbers, it has to go through their "media gateway" or whatever they call it to grab a physical dial line. If the call volumes are high and all the trunk/physical lines are tied up with other outbound (or inbound) PSTN calls, you'll get fast busies.

So is there anything I can do? This happens a lot and is very annoying. Is this typical of every Voip service? If not, I need to switch to someone other than Vonage.

Not much to you can do other than complain to Vonage.

I think they're having growing pains, not enough trunks, inadequate access links to the Internet, etc. I started with Vonage early last year and have noticed significantly worse call quality in December. It could be that a lot of new customers signed up over the holidays, or high Internet traffic volumes due to holiday shopping caused Global Crossing's backbone to be congested, or a whole host of other issues.

Before jumping to conclusions, get rid of that 2.4 GHz cordless and see how things work for a few days. Bradius may have fingered the problem perfectly, but you've got a known issue with that phone.

10-4. I'll do that and see how it goes. Go Dawgs! Smile

Just kidding, but I did notice your Yellow Jacket avatar. I went to Tech my first year, but it wasn't for me in several facets. Thanks again, Steve.

It's not the backbone ( at least not GX's ). Not going to go into how I can state this, but suffice to say it's true Cool

Pretty much it looks like the problem is that Vonage does not have enough Sonus GSX9000 ports attached to the PSTN to carry the traffic. Basically looks like they are cheaping out.

As a pretty ticked off customer of Vonage, I would like to get a real answer from them on why the fast busy issue is constant for me and is not getting better.

To make a call at this time requires 5 to 10 attempts. The interesting thing is that some of the fast busy calls I make, the other end actually rang and they answered but had dead air.

Currently I am stuck in "follow the script" hell with Vonage in attempting to get the problem resolved (last step was they did some "change", but won't tell me what it was, and told me to reboot the device). At least it's through email instead of trying to talk to someone on the other side of the planet. The English is at least mostly readable.

RT31P2 router, doesn't matter whether cordless phone or not (wouldn't matter anyways since I use 802.11a wireless in the 5GHz spectrum via a dedicated access point and don't have any problems with microwaves or cordless phones). Router is plugged directly into the cable modem and problem is there regardless of other network connections.
