Session Initiation Protocol and Short Message Service (SIP and SMS respectively) refer to frameworks that allow devices to communicate directly with one another without the need for a central routing computer. It seems rather surprising that a mere framework can so radically change the face of communication, but in the few years since their explosion onto the communications world, SIP and SMS have done just that.
The brilliance of SIP and SMS is that they are able to bypass the traditional telephony model whereby a line had to be routed through a telephone hub and maintained for the duration of a call to complete the conversation.
The process of routing and establishing connection as well as maintaining connectedness throughout the call in increasingly congested phone lines is quite an expensive venture.
And like all good for profit businesses, telephone companies were happy to pass the costs of operation on to consumers in the form of high long-distance bills.
That has all changed, however, since the advent of SIP and SMS.
Because the SIP and SMS code is based on computer communication and not telephone communication, it is able to work much like the internet itself.
That means that when you place a call through SIP or send a message through SMS you do not have to pay the cost of a router connecting your calls, but rather the technology automatically finds the person you are trying to communicate with and rings their line.
What is established is a stable but temporary connection in between you and the person you are speaking with.
When you are done speaking the connection is severed.
That means that unlike traditional telephone companies, SIP and SMS providers do not have to maintain millions of lines that are not being used, but rather they simply rely on the very precise code built in to the phone to create and sever connections as needed.
This creates a perfectly efficient system, which consequently explains why SIP and SMS providers are able to offer long-distance communication so cheaply.
SIP and SMS were designed not only with efficiency in mind, however, but also integrated ease of use in the model.
Because the designers were fully aware that telephone users have become used to having a handset and phone number, this has been integrated into the SIP technology.
Under the system SIP users can make calls from their number through a regular handset just like they would ordinarily.
However, because the system is based on internet and not telephone line communication, the benefits do not stop there.
Rather, SIP allows users to take their phone and plug it in wherever there is internet access.
And when they do, they can make and receive calls on their very same phone number.
So for instance, a business traveler can take his office phone with him on a trip and receive calls to the same number, on the very same phone, although physically he may have moved across the country or even across the world.
The fact that the system is based on internet communication also means that users get the benefit of paying their bill and adjusting their services all from a single website.
That is not to mention extra services like conference calling, which is significantly cheaper with SIP than with traditional telephony.
SIP and SMS allow users to send messages and phone calls from around the world with the ease of making a local call. Because the system is internet based it is able to offer a wide array of services and features that typical providers are simply not able to touch.
But by far the most important benefit of both SIP and SMS is the cost.
Due to the fact that the system is peer-to-peer, users are able to save tremendously on long-distance charges over their much more costly land-line competitors.

What to Do When She's Cold On the Phone
Recently, I received the following email from a member of the
on-line Speed Seduction? discussion group.(Yes, we actually offer
round the clock, 24 hour encouragement, advice on support with
and for thousands of Home Study course owners around the world!
How's that for backing up our clients and our products?)
Anyway, he asks about an important issue: what happens when a
woman who was initially warm to you, suddenly turns cold on that
first follow up phone call? Many guys blow this "test" and wind
up walking away from some potentially awesome women and fun,
fulfilling relationships. So let's hear what he has to say:
?Hey All,
After learning SS for four months, I have gotten some pretty
exciting results; specifically people react to me in a completely
different way. I am able to get rapport and...

Have you heard that you can make phone calls over the internet cheaply? Have you had a chance to try it? Most people that have had a chance to try it have experienced hit or miss quality, dropped calls as well as some speech delays. But there are some steps that you can take to really improve the quality and consistency of you VoIP calls over your internet Connection.
There is a lot of buzz these days around Internet based communication, VoIP, replacing regular/traditional telephone service. Much of the buzz has been created by/around a company called Vonage, who?s motto is ?Leading the Internet Phone Revolution?.

Explanation of EMF Protection Devices
by: Juliette Pickup
Look in your pocket or in your bag or on the table next to you. In one of those three places it is probable that you saw a device that could cause your injury or death at some point in the future. What is it you ask? What is it that I carry with me everywhere? What is this object that you say could hurt or kill me or possibly those close to me that I care about? It is your cell phone. The make and model are irrelevant; they all produce unnaturally high amounts of EMF or electromagnetic fields.
If it was just a threat to ourselves there might not be such awareness, but it's the fact that people near us that could be adversely affected as well. Those little bundles of joy that are the centre of your life are affected more than anyone else. The question you need to ask is: What can I do about all this? I don't have the power to get EMF emitting cell phones banned or anything like that....

The internet can be a great place to buy your next cell phone.
How many times have you been in the mall and were harassed by some pushy wireless telephone dealer?
The internet store is a sharp contrast to this type of environment.
On the internet, you can take your time, research a particular phone, and search for the best deals.
In addition to this, internet dealers generally have better cell phone deals than their brick and mortar competitors.
But how do you take advantage of these better deals?
In 2004, the government approved number portability.
Number portability allows you to keep your cell phone number, even if you switch carriers.
The implications of this are crucial for taking advantage of internet cell phone deals.
Internet dealers often offer some very innovative and high end cell phones for...

Overwintering the Garden Pond
by: Doug Green
It seems that there are always questions in the fall about winterizing plastic ponds. To begin with, clean out all the gunk (composed of fish and plant waste) at the bottom of the pond. Specialist garden catalogues have a little gizmo that attaches to a hose and when the hose is run, the gizmo acts like a vacuum cleaner, sucking debris from the bottom of the pond. Or you can put your pump on the pond bottom and...

2006 Honda Element: Unique Freak?
by: Matthew C. Keegan
I admit it. When I saw my first Honda Element a few years back I thought it was one of the most hideous looking vehicles on the planet. Then I saw the Scion xA and Scion xB, so I quickly relegated the Element to third place. I confess that my earlier feelings about the Element have changed, possibly because I see so many of them on the road these days and perhaps because I see its usefulness. No matter,...
