Is my ISP blocking my VOIP?

Considering that I was able to get an RT31P2 router with the bandwidth set to 30Kbps to work over a dial-up connection, I highly doubt upgrading to 4MB is necessary. What's your upstream rate?

I will note, the RTP300's don't currently use the bandwidth saver, just a full 90Kbps all the time. Awesome fax & data connections over it though.

The up stream currently is 250kb/sec, the up stream is good, its the latency, and high packet loss issue, that we have to deal with. All of this started August 1st 2005. We can use the phone between the hours of 1:30 AM to about 5:30 - 6:00 AM. Between these hours the phone is clear as a bell, with no chop. After that the chop starts out dropping letters in words and progresses to the loss of complete sentences. I can not say this enough, the Vonage techs have been wonderfull! Thank you guys and gals.

It is the same for me. I can use the phone until about 7:00 AM or so.. clear.. and then during the conversation.. I have problems hearing the other person.. every 4 seconds or so.. there is a gap in conversation... The person on the other end has no problems hearing me.. So it appears that voice coming in has problems.. This appears to coincide with test results from testyourvoip.com

So this tremendous packet loss inwards appears to be the results of the dropped voice bits...

Whoa... a 1.0!!! I'm getting ~3.4-~3.6 over the dial-up connection. Something's definitely screwed up there. All packet loss, I see, but not 100% packet loss... so maybe the ISPs just waaay oversold compared to the bandwidth they have.

But why did our phones work untill August 1st? Here is something worth reading from the FCC dated 08/05/2005, FCC Adopts Policy Statement, New Principles Preserve and Promote the Open and Iterconnected Nature of Public Internet. http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-260435A1.pdf
I thought I would share. When I run PingPlotter on my end it does show 100% packet loss.

Its 8:00AM and my phone is working, I haven't had phone service at this hour in over a week. Not holding my breath.

It's 2:58 PM and the phone is still working. Received a call back from city hall cable liaisons office. We explained the situation, and all the problems with the cable company, including how rude the local office personel were, and the song and dance routine from the supervisors over the phone. Good luck to those of you still struggling with their ISP providers. We are the ISP's customers, and we have rights!!

My phone is working also.. testmyvoip.com is great.

I forwarded to Champion Broadband the results from my 3days... I guess all our complaints worked.. Lets keep each other updated...

That was the reason I started this thread, was to see if anyone else had the same issue with the same ISP. What really set me off was the way the cable company passed it off as not their problem (we don't support that), and you should get our service.

Power to the people!
