Sipura Phone Problem – Buzz, Buzz!

Well, its been all of one day and already I’ve discovered a problem with my Sipura SPA-841. The phone apparently suffers from the same power-line-noise problem that the SPA-2100 terminal adapters do. Its an ever-present electrical noise on the phone – even when you’re dialing.

I would have hoped that Sipura had worked out this issue a long time ago, especially since so many customers have complained about it in their terminal adapters. It turns what was initially a fantastic choice for a low-end IP phone into a crapshoot at best. How long until the noise on the phone overpowers the speech? From my experience with the TAs, this problem is only going to get worse.

I’ll keep an eye out for future degredation, but I’m not hopeful. Sadly, purchasing Sipura products is still a gamble.

Cheap Thoughts: Broadband Changes

Wouldn’t it be great if your local cable modem company opened the throttle inside its own network? I know traffic bound for the Internet costs the cable company money, but internally it does not. Why can’t I send files to my neighbors and friends at 10Mb/s? I think its wrong to download from one cable modem to another and be stuck at 40kB/s. Once it might have wowed me (“ten times faster than smoke signals!”), but now 40 kB/s is just plain slow.

I would think it would be technically possible. Each cable modem has an internal, nonroutable 10.x IP address. The modems could be made to “uncap” traffic going to these 10.x addresses. Or maybe I’m wrong in thinking the modems have routing ability. At the present, the routing is handled by the head-end for most modems.

Anyway, wouldn’t be great to have a 10 Mb/s metro LAN for the price of two cable modem subscriptions?
