Technology: VoIP Phone Hype.....Phooey

VoIP Phone Hype.....Phooey

Written by Michael Lemm

I hold no ill will towards marketing, but do become offended when someone feels I should lose my critical analysis skills and buy into marketing hype.

For example - revolutionary new technology allowing 1 digit calling? Easy connect to VoIP via cell phone? Yada yada...hype & emotion... &..well you get repparttar idea.

The way VoIP works, there are several critical aspects to insure anything close to toll quality calling. First is repparttar 133351 instrument used. Next is repparttar 133352 inside wiring. Assuming both of these are not a problem, repparttar 133353 access line becomes repparttar 133354 next major factor. Here there are 3 points. First is quality of repparttar 133355 access line - its ability to deliver error free bit streams. Next is repparttar 133356 bandwidth. As a shared application, repparttar 133357 bandwidth must be sufficient to serve repparttar 133358 needs of both VoIP and all other applications simultaneously. Third is repparttar 133359 logical distribution of that bandwidth. In effect, repparttar 133360 bandwidth must be split between VoIP and repparttar 133361 other traffic to insure VoIP has a consistent available rate of communications between repparttar 133362 premise and repparttar 133363 POP.

Getting all of repparttar 133364 above correct is not trivial, and those who attempt a pure plug and play approach stand a fair chance in being disappointed with their VoIP service. But let's assume this all goes well (at both ends for an end to end VoIP call). The next issue is travel over repparttar 133365 Internet from ingress POP to egress POP. Different carriers have different paths, which impacts latency. A VoIP session is probably repparttar 133366 most sensitive to latency of all common applications (although live video is probably repparttar 133367 most sensitive). The carrier incentive is to keep as much traffic as possible on their own facility. This is a business need, not a technical need, but it does impact repparttar 133368 quality of service users experience. Multiple carriers provides protection against failure, but it does not insure true shortest path routing. More important than multiple carriers is repparttar 133369 ability and willingness to purchase priority transport of packets based on IP header information or other protocol approaches, so that a VoIP call continues as a high priority session and with sufficient bandwidth across repparttar 133370 carrier's network.

DS3 Service in the Los Angeles Market

Written by Michael Lemm

Searching for a DS3 in Los Angeles? Bandwidth has never been cheaper and Los Angeles is no exception to this. Many telecom companies built out their infrastructure in Metro cities and with repparttar

crash that has taken place since 1999 many of these companies have seen repparttar 133350

usage of their pipes decrease significantly. The infrastructure that was laid is a fixed cost that companies are eager to recover. The result of repparttar 133351

reduced number of businesses in repparttar 133352

market seeking service and repparttar 133353

drop in pricing has created a buyers market.

In a buyers market remember that you can push and probably get concessions from repparttar 133354 carrier but also remember that all carriers are not created equally. Many carriers may appear to offer a bargain price but you may be several hops from repparttar 133355 internet and have a problem with latency. You may also be using a small carrier that hasn't actually checked repparttar 133356 capacity of repparttar 133357 CO before you sign your contract and can't even deliver repparttar 133358 service they promised. The only way you'll discover this is when you start using your connection and find that at peak traffic times your connection is bogged down at a level below that which was guaranteed.
