That almost sounds like an invitation to check out what business service your cableco offers. One thing to be aware of with DSL and cable modems is that there can be various ill effects as your line gets closer to its rated capacity; do not expect that you'll get a reliable 512Kbps upstream. VoIP is sensitive to loss, latency, and jitter. You may be able, for example, to only get 384Kbps reliably out of the link (before packet loss/jitter/etc wreck its suitability for VoIP). That's a good time to look seriously at a gateway package like pfSense that can prioritize certain classes of traffic while also limiting overall bandwidth. As an example, we noticed on the local business cable offering (2Mbps up) Shaped PL min avg max stddev 2.2M 3 6.4 251 557 176 2.1M 1 7.8 350 584 134 2.0M 3 6.4 271 535 132 1.9M 1 7 254 527 131 1.8M 0 6 79 339 90 1.75M 0 5.9 14 92 11 1.7M 0 5.4 13 77 10 1.65M 0 4.9 11 69 7 1.6M 0 5.4 13 55 9 1.5M 0 5.3 11 59 7 1.4M 0 5 11 57 7 1.3M 0 4.9 11 54 6 1.2M 0 4.9 11 52 7 1.1M 0 4.8 14 53 11 The max starts trending up after 1.6M (helps to graph it) and pretty much everything goes to hell after 1.75M. ...
