Is Comcast tampering with its customers’ VoIP?

Leonardo Faoro - The VoIP Weblog


The odd things happening to VoIP users on Comcast’s network continue, even today.
First, there was my personal debacle dealing with Comcast support. Then, there was Jim Studnicki’s revelation of what certainly appears to be intentional penalizing of third-party VoIP traffic by Vonage. Then, just a few weeks ago, the Supreme Court decided, in effect, that Comcast and other cable companies don’t have to share their infrastructure with competitors. Now, another outraged Comcast customer has posted about his 14% packet loss when using VoIP.
This all begs the question—what in the world is going on at Comcast? It really does look like Comcast is intentionally blocking at least some RTP (VoIP) traffic in certain areas of the country. What has your experience been?

I just want to inform everyone to a new web site called VoIP Spear (www.voipspear.com) to measure your QoS. It's the Internet's best and most accessible QoS testing service. It utilizes packet loss, latency, and jitter to calculate a MOS score between 1 (very poor quality) and 5 (excellent quality) for your Internet connection. VoIP Spear runs 24x7x365 so you can always have an idea of what your VoIP QoS is.

VoIP Spear shows your QoS in easy-to-read charts. You can also have it send you email alerts when your quality drops too low.

VoIP Spear (www.voipspear.com) is free for personal use.
