Why You Need SIP Protocol For Voice Communications
March 1st, 2010 by ftsSIP (Session Initiation Protocol) is the communications technology for person-to-person real time traffic over the Web. Its defining specifications come from the SIP working group of the Internet Engineering Task Force. SIP provides access to the public switched telephone network for voice data at 3 kHz bandwidth and common number dialing using Voice over IP (VoIP). It can also be expanded to deal with IP telephony in conjunction with video and instant messaging. Future improvements will enable SIP applications like video conference calls, application sharing, home monitoring, and interactive gaming.
SIP is in most cases associated with a method to provide the functionality of typical telephony over an IP network. It is replacing the older, less flexible protocols used in the old days such as H.323 and MGCP. These earlier protocols worked at a very low level to link IP phones to the public telephone network. SIP, however, provides a sophisticated and straightforward way to network the enterprise. For example, SIP uses email addresses as the SIP address in place of a telephone number over the regular telephone network.
Suppliers of SIP hardware are quickly crafting new hardware and software to take advantage of this new Internet communications scheme. SIP telephones, PC client programs, SIP servers, routers, and firewalls are now on the market from companies such as Ingate Systems and Cisco.
Prior to installing a SIP solution in your business, you should think about the appropriate settings of your corporate firewall to accept SIP. Many of the common firewalls currently installed in business offices are not developed to support the SIP protocol. First, SIP media streams are transferred over dynamically allocated UDP ports that are often closed on firewalls. Second, SIP clients inside a firewall can not be reached using IP addresses since these addresses are local and unique to the LAN. Third, you need to ensure that either your T1 line broadband carrier or Metro fiber service is able to handle the SIP protocol from your internal network to the outside world. Your IT administrator will need to evaluate how to correctly support SIP to get around these technical issues. By including a SIP proxy and registrar for controlling the firewall, it is feasible to deal with complicated SIP scenarios for reliable and confidential communications.
SIP trunking provides multiple benefits to the business user such as cost savings, networking versatility, and emergency disaster recovery. It can do away with the huge subscription expenses of basic rate interfaces and primary rate interfaces. It also optimizes the bandwidth usage by delivering both voice and data over the very same connection. Businesses will have the manageability to route calls to favored carriers and the redundancy of using several service providers.

You can make these phone calls on the internet at a fraction of the cost of using a home phone because consumers all over the word using broadband internet are sharing the cost of the back-end network used to deliver the phone calls opposed to att having to build a network from the ground up for phone calls to take place on a standard land line.

VoIP, Why Replace Your Conventional Phone With VoIP
October 25th, 2009 by ftsIt is a fact that communication is one of the most important things in life. One example of a communication tool is the postal mail. However, because of the advancement in technology, more and more people now prefer email than the traditional postal mail. This is because its faster and much more convenient than traditional mail.
The fact that the internet have provided a fast way to communicate with your family, friends and business associates, people have been trying to develop this technology in order to improve information exchange. In today’s business world, it is crucial that you should have a fast way to communicate with other businesses in order to stay on top. Even small businesses are now taking advantage of the Internet to communicate with their clients. Without the Internet technology in your business, you will end up losing money instead of profiting.
The internet is now used by a new kind of technology that people call VoIP or Voice over Internet Protocol. This kind of technology uses the same principle of the traditional telephone but in a very different way. Instead of wires, VoIP uses the internet to transmit and receive data. This means that your voice will be transmitted digitally and in turn, will result in better quality and at a much faster transmission rate.
VoIP is what people today call the telephone of the future. It offers cheaper long distance calls and other features that is impossible or that is expensive in a conventional phone system for free. For example, VoIP offers features such as caller ID, audio conferencing, video conferencing, call forwarding, answering machine, call barring, and other features as a standard package. This would normally cost a lot of money in conventional telephones.
The fact that data is transmitted over the internet in digital signals, it also means cheaper phone bills and more reliable and much clearer connection. VoIP also offers free calls for anyone. The only catch is that the person you will be calling through your VoIP internet phone system should also be subscribed to the same VoIP service provider you are subscribed in. This will mean free calls wherever you are in the world. All you need is a high-speed internet connection.
These are only the few advantages of VoIP. There are more advantages that you can benefit from this phone system. Today, because internet connection is much stable than before and power outage doesn’t happen frequently, VoIP is indeed the phone system that you should get.
Basically, there are two types of VoIP internet phone system that you can use. One is the software and the other is the hardware system. In the software system, all you need to do is download and install the VoIP software in your computer. Your computer will be the one to act as the telephone. All you need is a microphone and a speaker hooked up in your computer. If you prefer to speak the way you do in a traditional telephone, all you need to do is purchase an internet phone. Some VoIP service provider lends you the internet phone for free as long as you stay with them.
However, if you prefer getting your own internet phone, you can purchase it in your nearest computer store in your area. Some phones have video capabilities while some looks like your conventional telephone. You can also convert your analog telephone to an internet phone by attaching an ATA. This tool acts like a converter. What this does is it converts your analog phone to a digital phone.
The only main disadvantage of a VoIP phone system is that when you get disconnected from the internet, you will also have no phone. And, since internet phones needs an external power for it to work, you can never use it in case of power outage. Analog phones have their own source of electricity in order for it to work even when a power outage occurs.
However, if your main priority is to save a lot of money on long distance calls, the VoIP phone system is for you. You can never imagine how much money you will save with all the great features integrated and also the cheap phone bill that comes with it. VoIP is definitely the telephone of the future.

How VoIP Broadband Phone Works
October 25th, 2009 by ftsThe VoIP broadband phone technology uses the packet switching abilities of the Internet in providing phone services. Compared to circuit switching, VoIP has provided several advantages. In packet switching, several phone calls can occupy the same number of space which is only occupied by one phone call in circuit-switched networks.
Take for instance, if you are making a 10-minute call from PSTN, it would also consumed a full ten minutes transmission time with 128kbps rate. But with VoIP, a 10-minute call is equivalent only to a 3.5 minutes transmission time with a 64 kbps rate. Therefore it allows you to extend your call time to another 3.5 minutes to consume the entire 128 kbps or accept other calls at the same time. This estimate reveals that 3 or 4 calls can still fit in the remaining spaces utilized by one call in the traditional system. The data compression can reduce further the size of every call.
Packet switching incorporated to VoIP works in this manner:
1. ATA accepts the signals send by the receiver after the user picked it up to answer. ATA is the most common and simplest way of service using the Analog Telephone Adaptor device which converts analog signals to digital signals. It allows standard phone connection to your computer or internet connection for VoIP use. The converted analog signals are transmitted on the internet.
2. Dial tones will then be sent by ATA to let the person know that there is an internet connection.
3. The person can now dial the telephone number of another party he/she wants to talk with. The ATA will convert the tones to digital data and store it temporarily.
4. The telephone number is sent to the call processor of the VoIP Company as a request form to ensure that the format of the data is valid.
5. Call processor will determine the person whom the person is calling. This is a hardware piece capable of running a mapping or database program (soft switch). Soft switches know the network endpoints, phone numbers associated with the endpoints, and current assigned IP addresses on those endpoints.
Soft switches contain the user’s database and phone numbers. If ever it does not have the needed information, the request is handed over to several soft switches until the answers to the request are found. Once the user is found, the soft switch also locates the device latest IP address similar to the requests. This relevant information will be sent back to the IP phone or softphone allowing data exchange among two endpoints.
The translation of phone numbers to IP addresses happens through a soft switch which connects two devices on either way. So, if one end is doing the call, the signal is sent to another end through ATA making the telephone ring. Soft switches should work in tandem with the network devices in making VoIP possible.
6. If the person picks up the receiver to answer, then the sessions between the two computers is established. Each system will know that data packets from other system are expected to arrive. The typical Internet infrastructure will handle the call like e-mails or web pages. However, the protocols used by both systems must be the same for them to communicate. Two channels is implemented, one for the direction and the other is for the session.
7. There is an allocated time for conversation wherein packet transmission occurs between the two computers. These packets are translated by ATA into digital signals after receiving it and then convert it again into audio analog signal to be heard. The ATA also keeps an open circuit between itself and the analog phone as it forwards the packets to IP hosts on another end.
8. The receiver will hang up when the conversation is finished. This will close the circuit between the ATA and the phone.
9. The soft switch will receive a signal from the ATA informing it to terminate the session. Packet switching let the data networks understands how technology works. The abilities of how computer communicates are immediately gained by telephone networks.
Compared to any other emerging technology, VoIP has provided essential advantages and most developers will still keep on refining it until it replaces the existing phone systems worldwide.

Features Of VoIP Phones And The Great Ease It Provides
October 25th, 2009 by ftsVoIP (Voice over Internet Protocol) Phones are really no ordinary phones; they are considered mobile but still needs to be connected through a wire. Its functionality is far more modern than landline and mobile phones though VoIP phones have features that can be found too in a typical landline and most cellular phones.
In landline and mobile phones, caller ID, voicemail, fax, 3-way calling, call blocking, call waiting, call forwarding, Last number redial, 411 directory, local number portability and 911 service are the most present and offered. These types of phone services may have other features aside from listed above.
With a VoIP phone service, those features enumerated above are only basic features that every device and service have. Some operators or providers do not ask any extra payment for the basic features.
For a clearer understanding of all the basic features of a VoIP phone service, here are some information to read.
CALLER ID
This is a feature that will let a receiver know the caller’s number and identity. Every time your phone rings, the caller’s number and identity will be displayed in the screen. Actually, only the number of the caller will appear in the phone’s display screen unless otherwise, the caller is included in the saved contact entry phone memory. However, callers that have the same network provider as yours will have their name displayed on your phone every time they call.
The term for the caller ID varies according to the provider and country. In some countries, caller ID is rather termed as Caller Line Identification Presentation (CLIP), Call Line Identity (CLID) or Call Capture. Call Display is what Canadians refer to caller ID. When a caller ID is provided through ISDN phone line, it is called a Calling Line Identification or CLI for short.
VOICEMAIL
This is a good feature to busy persons that doesn’t have enough time to catch all calls for the day. This is basically a recorded voice message of the caller whenever nobody answers the phone. Answering machines are the counterpart of the voicemail feature. The difference between the two is that, voicemails are saved in the network and can be retrieved through a network system, while in answering machines; voice messages are stored in the machine’s memory or in older versions in a recordable tape.
Voicemail are activated when a caller reached the maximum rings programmed by the network. When the maximum allowed rings are reached, the network automatically diverts the call to the voicemail.
FAX
This feature is commonly known as IP Faxing. While landlines use its own network to send and receive fax messages, VoIP phone services utilize the internet to transmit and accept such messages. This feature works by transmitting fax data on the internet and is forwarded to fax servers. Fax servers then convert the data and are transferred to a normal telephone connection. It is then received by the party the message is sent to as a normal fax.
3-WAY CALLING
Using this feature will allow you to talk with a maximum of 3 persons at the same time. This means that the conversation is heard and done by the three parties. Telephone Conferencing and 3-way calling is the same in terms of its purpose and concept. However, in telephone conferencing, one may call more than three persons at the same time.
In the future, multiple-way calling will now be available allowing one to call more than three persons at the same time.
CALL BLOCKING
Call blocking is a basic VoIP phone feature in which one may block a caller. This can be possible if you add the name and the number of the person you want to block in your blocking list. Calls from a blocked caller are automatically rejected and your phone will not ring.
Many people use this feature for call management purposes. Unwanted and unsolicited calls are annoying and for sure you do not want to be disturbed by such. With the use of the Call blocking feature, you can filter callers and allow those who you want to hear only.
CALL WAITING
The concept of call waiting is very simple; allowing two callers to be on the line while one is on line and the other is on hold. With call waiting feature, important calls can no longer be missed. Many people use the call waiting feature because it greatly aids them to receive and answer all calls while they are in the phone.
VoIP phones do have other features that are not present to landline and cellular phones. Because VoIP phones use the internet for connection, there are plenty of features that are supported by wide internet capability.

Though the softphones sounded highly thrilling when they came out first, they had some drawbacks: You could talk to somebody only when that person was online and had a computer with the same softphone as you were using.
While this basic way of making free calls remains popular even today, the internet telephony has advanced a great deal over the years.

Why So Amazing About Voice Over IP
July 23rd, 2009 by ftsVOIP (Voice Over Internet Protocol) is simply transmitting Voice over the internet or other networks.
VOIP comes in different forms like strictly computer to computer transmission, Computer to Internet Phone or Phone to Phone. Computer to computer voice transmission is fairly common now, most people don’t think twice about it. For example, Windows Live messenger now allows you to have voice conversations with your contacts. Ventrillo is a widely used program among internet users, especially among players of Massive Multiplayer Online RPG’s like World Of Warcraft. It is very simple: join a channel and you can hear and speak to everyone in that channel, all you need is speakers and a microphone.
In terms of making and recieving calls with your computer to actual telephone numbers the most popular program is probably Skype, which is used by millions of users a year. It can be used on Windows, Macs, Linux and even on mobile devices like the IPhone, devices with Windows Mobile or Nokia Nst-4. Very handy if you need to make a lot of long distance calls, Skype allows users to have a regular local phone number from a variety of distant countries, so you will pay the same rates as if you were using a local phone number. You can also make calls between two computers using Skype. You can also purchase Skype phones connected to your network via Wifi. There are a few drawbacks with using this service however. For starters, if your computer is not turned on or if you lose your internet access you cannot recieve calls and wont know people are calling you. Also you can’t call emergency numbers like 911 if you are in trouble so you can’t safely rely on it as your only phone. The pro’s outweigh the negatives though and it is a great technology to use.
Then there are VOIP home phone providers, just like regular service providers they charge for phone service. Your phones will look just like regular only instead of being connected to the phone lines your phones will be connected to your router by Ethernet or wireless. One of the main Voip providers in the U.S, Canada and the U.K is Vonage. Vonage is currently offering unlimited local and long distance calling for $25 a month. Some of the other major VOIP service providers are:BroadVoice, Viatalk, VOIP.com, Lingo and numerous others. VOIP phones cannot use traditional 911 services because they cannot see where you are calling from but many offer e911 to route 911 calls to the appropriate jurisdiction. In many cases this feature has to be activated for an additional price. Another concern with VOIP is that you must have a certain internet speed for it to work effectively, you also need to be constantly connected to the internet so if you are still using dialup then forget it.
Voice Over Internet Protocol is a important new technology that has been gathering steam for some years now, in the future many believe that the majority of phone calls will be over IP based Networks.

Benefits Of Making The Switch To VOIP
June 26th, 2009 by ftsIf you are still using landline phone service, then there is a good chance you may be paying too much for your phone service. Make the switch to VOIP phone service and you could be saving a lot of money over time.
So what is VOIP? Voice Over IP or VOIP is a system that allows users to make phone calls over the Internet’s broadband connection. Using one of three styles of phones (Analog Telephone Adapter, IP Phone, or Computer to Computer) the caller connects to the system and the call is routed via the IP address and connected. Long distance phone calls made over VOIP are either free or very inexpensive, making it a great rival for the outdated and very expensive phone company.
Why Make The Switch To VOIP? Well, there are a number of reasons to purchase VOIP. For many people, the main reason to switch to VOIP is that it is much more inexpensive than paying for landline phone providers. The reason it is cheaper is because it uses multiple packet switching technology, rather than phone companies who use a public switched telephone network (PTSN).
The PSTN uses the circuit to make a call. During the period of the call, the circuit is open, barring any further use of that particular area in the network until the call is ended. The voice over IP network however, uses packet switching to be MORE EFFICIENT and therefore CHEAPER. With the old circuit networks, there was a constant need to add more and more circuitry to keep up with the demands of an ever growing base of communication customers. Packet switching allows data to be “packeted” and then sent along the network via whatever pathways are most open at that moment. The packet then makes it to the intended recipient in a matter of seconds, directed by the IP address that was used to begin the call.
Another reason purchase VOIP is that it is also very effortless up, which makes it a cinch to start using right away. Making the switch to VOIP also entitles you to most, if not all or even more, of the features that landline phone services provide.
There are a lot of VOIP providers out there who claim that they are the “best”, so it can be difficult to judge which VOIP provider to switch to. Out of all the providers on the market, Phone Power has the be the best one on the market. Because of the number of features, cheap price, and call quality it is definitely the best one to pick. There is a very good Review for Phone Power that goes in depth on the pros and cons of Phone Power.
Overall, Making the switch to VOIP is highly recommended as long as you have a high speed internet connection like DSL or cable. Don’t wait to get VOIP, because you will just be wasting more money on your landline phone service, when you could be SAVING MONEY with VOIP. VOIP service is only increasing in popularity and advancing in technology, so it makes sense to switch to VOIP. After all, people communicate every single day, so why should you pay more to do it?
