Telephone IP - PBX Service - IP PBX Service - PBX Service Provider

Telephone IP - PBX Service - Voip IP PBX Service - PBX Service Provider

An IP-PBX telephone switch is a dedicated server to switch telephone calls, managing all internal and external communications for IP telephony. This way all the extensions handled by this team finish in IP phones, telephone adapter ATA, Softphone or SIP servers.

An IP-PBX can connect remote extensions. Therefore an IP-PBX with office in Hong Kong, for example, can have several internal (branch) connected in Caracas. Users in Hong Kong and Caracas are part of the same telephone exchange as a digital extension to communicate with each other. These communications are free because it uses internet connection.

Another possible configuration is to hire minutes of IP telephony and a mix of technologies to lower costs. Suppose an office receives calls by the traditional method (analogue line) and make calls by several providers minutes. This can cut costs by up to 90% by telephone.

Because the advantage of IP-PBX is able to connect a group of people with other groups in remote locations, is designed for use by companies or organizations with a good long distance traffic, or branches of international companies.

PBX Systems - Strengths - Weakness

PBX Systems - Strengths - Weakness

A PBX, which is also known as a switch or telephone switching device in the phone, is responsible in the connection of office telephones in a business with the public telephone network. The only stronger competitor in a PBX 'would be a voice over Internet Protocol. There are many interesting points with regard to both, and you must ultimately decide which system best meet your needs phone system.

Features System of IP/Pbx

Today, it is expected that PBX systems handling a very wide variety of duties beyond just simple connection to a public telephone system. The initial functions of a PBX are to route incoming calls to the appropriate extension in an office and the telephone lines between extensions. Over time, many new features have been added, such as automated greetings for callers using recorded messages that, marking menus, links to voice mail, automated call distribution, teleconferencing, and more. The range of features offered by a PBX will vary, generally in proportion to the price of the system chosen. Some of the most popular answer calls that may include a custom business greeting, and the supply of a single business number that gives access to all employees and company departments. The system can offer a menu of options for conducting a call, such as connecting to a specific department or an extension and providing a directory of employee extensions accessible by entering the digits corresponding to employee's name. A PBX system can also evenly distribute calls to a department among available employees at that time, it allows transfers or calls between extensions, calls multiple extensions of the conference with the employee, provide detailed call records and management system in real time, place callers on hold while waiting for the jobs available in the department of music and messages of the game or custom whenever callers are waiting on hold. Although this is an impressive list of features, remember that not all are available at each of the PBX system. The most difficult is to provide automated call distribution (ACD), and generally, the merchants charged a premium for products that include this feature. If a feature is not included in the PBX system of the database, you can most likely be purchased as additional add on.

Strengths of the IP/Pbx

Hardware PBX (PBX phones) is a mature technology that offers many advantages for the right type of use. At a minimum, multiple extensions in one office can share the cost of telephone calls. No need to pay a separate line for each extension. Capital costs for equipment and can be amortized over time despise. Although management and system maintenance costs continue adding after installation, the systems of today are more robust and easier to handle than had been in the past. Incoming calls are typically free or cost very low. In more expensive systems, a certain level of the extension system allows for the better. Businesses that can reliably predict their needs can usually find a profitable system. As the features and functionality continue to be added, a PBX can add productivity to an office environment. Almost any feature you can imagine for telecommunications can usually find somewhere among the many vendors and offerings in this space - as long as customers are willing to pay the price associated.

Weaknesses of the Pbx

The biggest problems with the standard PBX systems revolve around the issues of flexibility, cost, and adaptability. Costs are a big problem in two separate areas. First, get one of these systems, PBX phone service can be extremely high. If you decide to buy a system that is at the lower end of the price scale, the team will have a few features, extensive options such as no voice mail or automated call distribution offers. Many smaller companies find they can not afford the cost of a PBX system, so we continue to call on individual lines, never developed a unique business identity. Another issue involves the cost of PBX systems maintenance and support system. As the team continues to add new functionality PBX, there will be a need for highly trained people to help maintain the hardware, software and roll out of improvements to the system and management system. This, in all likelihood, end up it is absolutely expensive. As with so many devices based on the infrastructure of hardware and software, the other problem with the PBX phone systems to be flexible. Most PBX hardware is limited in its flexibility to add more lines for internal and external support more users. The low end systems are extremely difficult in this respect. Small businesses may need to purchase a new PBX system every two years to accommodate its business growth. Flexibility also end up being an issue when it comes to features. While almost any feature can be purchased at the end, many times, the important features you can not add to an existing system, which would end up forcing businesses to buy brand new systems to get the features they need or want.

VoIP Pbx against

Many businesses and individual business owners are considering the PBX to VoIP. There are some similarities between the two systems, but there are differences, too. Your responsibility as a business owner is to weigh the pros and cons and ultimately decide what would be the best option to meet your needs. Some things you need to consider include ease of use of the system and its employees, the costs incurred with the new system compared to your current phone system, the installation cost, and past, the quality of the system is reliable and whether your company's needs. If you understand the importance of these concerns, then you will see how important it is to make a comparison against PBX VoIP. This, unfortunately, will not be easy, and hopefully you've done some research online to get an idea of what may be the options. The fund, though, is that each company is selling the service will advise you that your service is in fact the best. This will discourage this. Be in your best interest and interest of your company better than your first one is clear what is VoIP.

Voice of Internet Protocol

Voice over Internet Protocol, or VoIP, can turn a regular connection, an Internet standard way to make free phone calls actually. The positive aspect of this is that using voice over Internet Protocol software that is available to make Internet phone calls, you are bypassing the phone company and their cargoes. VoIP is the revolutionary technology has the potential to reinvent the world's phone systems. VoIP providers have now been around for a while and are growing steadily. Important telephone systems are already in the process of creating the voice over Internet Protocol calling plans in several markets, and the FCC is investigating the ramifications of VoIP services. The overuse of the Internet Protocol voice has been a subject of interest almost from the first computer network. For 70 years, the voice was transmitted over the Internet. Technology for voice conversations transmitted over the Internet that has been available to end users since at least the nineties. In 1996, the first came with the VoIP Caller ID and voice mail as additional features, but it was only possible to talk to others having the same software. Has been steadily progressing ever since. Something that is extremely interesting and different systems over Internet Protocol is the voice that more than one way to make a real phone call.

Three different systems of VoIP Services

There are three different systems of VoIP services in use today. The first is the simplest and most common. Is through a device called an ATA (analog telephone adapter), which allows you to connect a standard phone line on your computer or internet connection for use with VoIP. The ATA is an analogue to digital converter. It takes the analog signal from your traditional phone and converts it into digital data passed through the Internet. You just remove the ATA from the box that came inside, fold the cable from your phone that would normally plug in the wall ATA, and you are ready to make calls. As follows to make a VoIP call is through an Internet phone protocol (IP), and these phones seem just like regular phones with a handset, fork, and buttons. Instead of having standard phone connectors, IP phones using an Ethernet connection. IP phones connect directly to a router and have all necessary right hardware and software onboard to handle the IP call.

Last, and probably the easiest way to use a VoIP phone, it is computer to computer. You do not even have to pay calls. There are actually several companies out there now who are offering the software free or extremely low cost that can be used with this type of VoIP. All you need is the software, a microphone, speakers, a sound card and an Internet connection. Preferably, the Internet connection must be fast as a DSL modem or cable. With the exception of its normal monthly fee for the ISP, there is usually no charge for calls from computer to computer, no matter what the distance may be.

Pros and cons of voice Internet Protocol (VoIP) service over home

Okay, so what about the service for the home? Although the best option for the landlord service is VoIP, there are pros and cons with respect to this measure at home. Home VoIP services have several traditional telephone services over the benefits. One of the main advantages of using VoIP in the home would be the low cost of operation. For the same services that VoIP provides, such as calls or calls in the country, the VoIP phone providers usually charge a fee lower than normal telephone charges. Another advantage of the popular VoIP service for home would be its flexibility. While normal telephones are permanently linked to their phone lines, an ATA may be taken anywhere in the world with you. One can tie it with a normal telephone and an Internet connection and make VoIP calls to any other ATA in the same network and not incur any additional costs. Honest, there are not many disadvantages of VoIP at home. The biggest disadvantage of home VoIP service is that it is dependent on a direct energy source, like a cordless phone. If power is lost, the current VoIP is also lost. Another connection with the home VoIP sound quality is contrary. The sound quality can be fickle, and some calls may be delayed and even echoes, too. This will lead ultimately to the calls that will not be as clear or as smooth as the telephone call.

Understanding Your Options

As you continue shopping for the best for your business, a PBX phone system or VoIP, you will want to consider both options before coming to a final decision. The biggest advantage of a system over Internet Protocol or VoIP is the voice the way you ultimately bear to say aloud the state or country. Because the rates are much lower with VoIP, many businesses consider when deciding extreme value to take this route instead of the PBX phone system. When it comes down to cost factor, VoIP wins hands swallowing. Fund, the more you end up saving on phone calls, more business and you can get more profit can be made. Another positive point is that VoIP allows for a less costly installation. VoIP services usually just connect to Ethernet, simply and easily. Most computers, systems and telephone, and fax machines already have this feature built inside. Realistically, everything you need to do is plug in everything and you're ready to go. But in the ongoing battle between the PBX and VoIP phone systems, when it comes to the desire to have extensions and the latest phone system features and uses of the PBX, you may not be able to achieve this through providers of VoIP service. Instead, you should stick with the PBX or other phone systems look possible.

Understanding Services

Something that is also extremely important to understand is the service that each of them has to offer. While the PBX is a system that lets you have multiple lines connected to an online service, you must also understand that VoIP is strictly through the Internet. Due to the large difference between the systems, allows a product and a totally different result. You also will want to remember and observe the importance that services tend to change all the time, too. An example of these changes is that with the ongoing development of new services and products, is becoming much less expensive PBX systems now installed. In the past, the cost of installing a PBX phone system was so high that forced many small businesses and even larger majority to look elsewhere for their needs. Now, because of new developments, they can fill those needs more options than ever before. The PBX is becoming much more affordable for these companies, thanks to new, improved technologies. One can expect the battle between the PBX telephone systems and technology excessive Internet voice (VoIP) is turned on for quite a long time. You will be sure to have different reasons for the desire to choose a product over another, across the range of reasons for the cost to voicemail. The best suggestion is the simplest. Do the research for each company, and do your research on the web to see just how well your decision will fit your needs. The answer to the question about which to choose, the PBX or VoIP, only you can decide ultimately by the business and the individual.

When trying to decide between the PBX telephone systems and VoIP systems, many factors must be taken into careful consideration. It's something you can not tackle or do quickly. The time must be taken, the investigation must be made, and the cost and flexibility should be taken into consideration. Then and only then will you be prepared to take the right decision for your employees and your business.

Settings description of PBX and IP PBX

It is increasingly more common for organizations to acquire, install and maintain hardware components, such as the central switch (PBX) or IP PBX, which are required to admit their own telephone systems. Many organizations purchase their own telephone equipment and train its staff to reduce costs associated with maintenance of its telephone systems and because they want greater control of telephony features offered.

For an organization to possess and maintain a telephone network, you must purchase the hardware needed. It should also take into account the daily maintenance of telephone equipment and training necessary for your staff to manage the telephony system. This topic discusses the different types of telephone systems and business or organizational components of telephony hardware required. It also provides examples of different types of telephony configurations.

A PBX is a legacy PBX telephony device that switches calls in a telephone network or circuit switched. A legacy PBX is a PBX that does not have a network adapter and can not transmit packets. Not being able to transmit IP packets, some companies and organizations have replaced legacy PBX to IP PBX. For a list of supported PBX for Exchange 2007 Unified Messaging, see Telephony Advisor for Exchange Server 2007.

Most companies use medium and large PBX. PBX enables users or subscribers to share a number of external lines for making telephone calls are considered as external to the PBX. A PBX is a much less expensive to provide each user with a telephone company outsourcing. A PBX can be connected telephones, fax machines, modems and other communication devices.
Typically, the PBX equipment is installed in the organization itself and connects calls between phones in the organization and the telephone company. Normally, there are a limited number of external lines, called trunk lines, to make and receive calls outside the company from an external source such as the PSTN.

To enable a legacy PBX for use with Exchange 2007 Unified Messaging, you must implement a gateway IP compatible. For a list of IP gateways, see Telephony Advisor for Exchange Server 2007.

IP PBX An IP PBX is a PBX that has a network adapter compatible with the IP protocol. It is a piece of telephone switching equipment that normally resides in an organization or company rather than being located in the offices of a telephone company. There are two types of IP PBX: IP PBX and IP PBX traditional hybrid. Both traditional and IP PBX, IP PBX hybrid are consistent with the IP protocol for sending voice conversations in packets based VoIP phones. However, hybrid IP PBX also connects traditional analog and digital phones.

IP PBXs are frequently easier to manage than the legacy PBXs, because administrators can easily configure the IP PBX through an Internet browser or another IP-based tool. Furthermore, it is not necessary to install cables, wiring, patch panels or additional. With an IP PBX, to move an IP phone based simply unplug it and plug it back elsewhere. This avoids the costly services needed to move a phone from a legacy PBX provider. Likewise, organizations that own an IP PBX do not have to bear the additional costs of infrastructure needed to maintain and manage two separate networks for circuit switched and packet switched. For a list of supported IP PBX for Exchange 2007 Unified Messaging, see Telephony Advisor for Exchange Server 2007.

IP PBX Configurations

An IP PBX is a PBX that supports IP phones to connect through an Ethernet LAN or packet switching. Send IM conversations into data packets or IP. An IP PBX can have multiple interfaces. These include interfaces to a data network and other interfaces that allow connection to a telephone network or circuit switched.

The development of Internet protocols in real time has been correctly can send voice messages and faxes by a data network. Among these protocols of the Internet in real time including VoIP protocols that are used with Exchange 2007 Unified Messaging: Session Initiation Protocol (SIP) over Transmission Control Protocol (TCP) for voice and T.38 messages to faxes. These protocols have been successfully able to send voice messages and faxes by a data network. VoIP protocols in real time are necessary to maintain order and control the delivery and synchronization of data packets to send voice messages through a data network or circuit switched. Failure to use these protocols to maintain and control the delivery order and synchronization of data packets, the voice of the people would decompose and the sound would be inconsistent or images could be confusing. For more information about the VoIP protocols that are used in Exchange 2007 Unified Messaging, consulteDescripciĆ³n protocols, ports, and unified messaging services. For a list of authorized IP PBX in the Exchange 2007 Unified Messaging, see Telephony Advisor for Exchange Server 2007.
