Just a guess, but could his power supply going out cause the humm?

Good thought, but the fact that there's no buzz until he plugs into the network makes it a bit unlikely.

Have you tried the Voip test at testmyvoip during the same hours / while you are getting the buzz on the line?

what device do you have and have you had Vonage techs switch the phone ports

also what firmware do you have on your device

I'd be curious to see if the cable line coming into the house was properly grounded. Most cable modem power adapters don't have a grounding pin, so if the line itself isn't properly grounded very interesting things can occur. It might not be peak traffic times, but rather someone turning on a device that is backfeeding into the cable plant at intervals that would coincide with peak traffic times.

As has been stated earlier in this thread, Comcast can't make your line buzz. They can make your audio choppy, they can introduce delay, and they can cause disconnections if they want to. Nothing they can change on the IP network can introduce buzz/hum, static, or distortion.

Well, I'm telling you the facts: there's no buzz until I plug into Comcast's network.

Now, lest you think I'm dismissing you out of hand, I do get a similar buzz from running a fan or heater nearby the line. That is definitely an analog issue relating to interference the line. But of course I get that whether or not I plug into the network.

The buzz I'm getting is also "clickier" than the analog buzz from the fan, which is a lot smoother, as if each lost packet is a click and the net result of the clicks amounts to a buzz. I think I'm getting a digital problem that imitates an analog problem. Hell, maybe they're doing that on purpose to confuse people.

There appears to be nothing I can do about this. Guess I'll switch this weekend.

could also quite possibly be electrical interference. you never know. try a line conditioner

I'm reading this thread with interest.

For the past 7-10 days, I've been unable to use my Vonage line in the evening. It seems to work fine during the day. The symptoms are a loud clicking, or a long burst of static (from my end...a short burst and dropped connection from the other end, I'm told) and once I suddenly found myself listening in one someone else's conversation with crystal clarity.

Vonage Tech Support seems unable/unwilling to help me. I've rebooted everything, and I've simplified the connection to the point of: cable modem, wire to Linksys PAP2 Vonage device, wire'd phone. And it still happens.

After 3 exchanges with Vonage tech support, each of which giving me a long checklist of information needed or things to try, I was 'escalated' to the next level of support. Their 'help' was to ask if I had a phone splitter in use because that could cause the problem.

I mean, come on, that's escalated support? We covered that back in email exchange #1.

I'm not sure what to do or where to turn next. I've had Vonage for about 13 months and have been totally thrilled with the service until now. But if I can't use my phone (connections go wonky after 2-3 minutes,every time)...

Any ideas as to what I could try?

I have a similar issue and can verify that it was introduced when I was transitioned from Adelphia to Comcast. I have setup QOS on my router and the phone calls have improved. But....

After about 2 hours on the phone with 8 different people (adelphia tech, adelphia billing, comcast tech, comcast billing, etc). They have told me that there are issues with the transition and my service should be back to normal by today (13th), which i realize can be complete BS.

I can verify that they have cut my upload speed in half (768 down to 384) when I was transitioned without notice and without any change in billing. Comcast billing also stated that would be back to normal as bugs are ironed out. Comcast did issue me a $20 refund for the days being cut down to 384.

I was paying for 6mb down and 768 up with Adelphia, and now I am getting about 4 down and 384 up. My cable modem has been provisioned with comcast as a 6 mb down and 384 up plan.

Comcast "could" identify SIP packets and reduce the QOS for these types of packets (similar to what I do with QOS on my router, but I give SIP packets premium priority). I really doubt they would take the time...

Talldave, call my cell later today and maybe we can figure out some sort of QOS setup on your router to try and resolve this, or at least make your calls a bit better. You know the number we already talked this morning.
