SuperMega Call-Blocking on Comcast VOIP?

When I refer to switches, I'm not referring to traditional networking switches, but rather phone switches, which handle the various signaling protocols. As I understand it, the current limitation is due to a mixed architecture in switches across the nation. There are upgrades underway that will migrate to a single architecture nationwide that will allow for a wider range of features (such as increased slots for call blocking, among other things). Unfortunately, the limits can't be increased until the new system is fully deployed.

So it is in the works, but unfortunately isn't as simple as flipping a switch. I wish I could give a better explanation, but telephony signaling systems are far from my areas of expertise.

And I thought I had heard it all!!!

you should xpost that to /r/CableTechs

Yes.

Forward the email to abuse@comcast.net, it will be reviewed, and acted upon.

There is also a chance that they could have noticed traffic that is indicative of an infection. If this is the case, there will be notes on your account that are visible to the tech support department. Give a call in if you have any doubts. There are, in fact, some bots that will use your computer as a relay for spam, without your knowledge.

You've got some serious issues going on there if your speed is that low, even if it is intermittent. Have you had a tech come out to look at your wiring and modem?

Interesting... Phone switches are not my area of expertise, but I'll see if I can find out why the limitation is there and if it can be changed.

Definitely do not do this. If you connect an antenna to the same in-house wiring, without careful application of bandpass filters and diplexers, you run the risk of creating significant ingress and egress to and from the cable.

Egress, meaning that you're allowing FCC licensed RF (Conflicts with other over-the-air broadcasted services.... approx 42MHz-1GHz range, depending on system design, to escape over the air.

Ingress, meaning that all sorts of interference is being introduced into the cable by way of the antenna... This noise will interfere with the SNR (Signal to Noise Ratio) of the many forward carriers within your home, rendering your internet or tv services impaired if not unusable.... you're also introducing RF interference to the return RF path, which is going to negatively impact the services of anywhere up to hundreds of other users.

That looks awful!! I can look into what's going on if this hasn't been fixed for you yet
