Phone branch exchange (PBX) is the traditional telephone system that many companies have gotten used to. Many people are worried about switching from their traditional PBX system to an IP (internet protocol) PBX system that incorporates VoIP and SIP. Although there is nothing wrong with the traditional PBX system, an IP PBX system can benefit your company and prepare for the future in more ways than one.

First of all, when it comes to installation and configuring, IP PBX is a lot easier to operate. The traditional PBX system is almost impossible to install on your own. Furthermore, anytime you need to upgrade or add more services, you will need to pay another installation fee. With IP PBX there is a software program running on your computer which means anyone with an understanding on basic Windows can install and configure the IP PBX system. Furthermore, VoIP Telephone systems are scalable which means you can easily add more phone lines or extensions. Your company is most likely going to grow; make sure it does not outgrow your telephone system by upgrading your traditional PBX to IP PBX.

Another plus with the IP PBX system is that you do not need separate phone wiring. It uses a computer network connection. For those who are moving offices or for companies with several different branch locations, an IP PBX can save you precious time and effort on installation.

IP PBX systems use standard phones and there are no vendor lock ins. All IP phone systems use SIP as a protocol which means you can choose any SIP VoIP phone hardware for your service needs. You are in the driver’s seat.

Then, of course, there is the price different. IP PBX phone systems can save you a small fortune on international phone calls, branch to branch calls, and national phone calls. IP PBX also includes free features such as call waiting and caller ID. You cannot deny the price drop with IP PBX systems.

These are only a few of the differences between the traditional PBX and the IP PBX telephone systems. The more you know about the traditional PBX versus the IP PBX, the quicker you will want to make the switch.

VoIP security has been called in question recently, though there is little evidence to indicate that VoIP security is any less than conventional telephony systems.

VoIP voice data is transmitted via a packet-switched data network using IP. VoIP systems can carry a significant higher number of calls, and very much faster, than traditional PSTN networks due to compression of the voice packets, modern broadband technology and a number of other gateway developments which have reduced the previous packet delivery problems to an extent that the protocol is now a viable mainstream telephony solution to most business needs.

VoIP security should therefore be shown to be at least as effective as that of traditional telephone systems.

There is actually very little difference between VoIP security and that required for any other type of data transmission system. Look on it the same as you do your email system. The same as your office LAN if you have one. You probably have a system in operation whereby only authorized personnel can use certain aspects of the network. VoIP security can, and do, use the same techniques.

However, having said that, let’s have a look at potential weak points in VoIP security that budding hackers may see as good points of attack.

IP PBX CALL MANAGEMENT BOXES

PBX stands for Private Branch Exchange, and is piece of software running on a server. It’s function is to deal with all the switches and connections involved in the telephone system. These can be attacked by hackers or viruses which could compromise sensitive data. VoIP security systems are designed with this risk in mind.

PBX equipment should be placed behind firewalls, locked down and regularly monitored for unwarranted intrusions using intrusion-detection software. It is also possible to put the server in a different domain from the rest of the system, making it much more difficult for intruders to reach. PBX security is a basic aspect of VoIP security systems

GATEWAYS AND DATA PACKETS

The gateway’s job is to convert voice to data packets, transmit them then receive and convert the packets back into voice. These are a potential VoIP security risk in that thy can be hacked into unless there is an access-control system in place to prevent unauthorized people from accessing the system. VoIP calls should only be permitted to specific people, and most good VoIP security systems allow only authorized user to operate VoIP systems under password control.

The data packets themselves can be hacked into using data-sniffing techniques. This can be a serious VoIP security risk and packet sniffers, as they are often called, capture binary data passing through your network and can reroute it to a computer on another network for decoding into a readable form. In order to do this, the ‘sniffers’ has to be on the same network wire as the packet is using to reach its destination. The problem in installing an effective VoIP security system is that there is usually a lot of information passing at any one time, and the hacker has a higher probability of getting useful information than from a conventional telephone system.

Encrypting VoIP traffic and routing it through a virtual private network would reduce the VoIP security risk, and most corporate systems have multiple encryption layers for external messages. Internal security could be improved by running internal VoIP messages through this corporate network. Small businesses should seek the advice of their supplier, or of a security expert if they feel that they may be subject to such attacks.

However, VoIP security advisors can point small to medium companies in the right direction. Corporate VoIP security is generally not so much problem in that it is normally contracted out to expert advisers.

In the final analysis, however, there are no real differences between VoIP security and the normal security concerns associated with any data network service, such as normal office internet and email LANs. The security firewalls and restricted access to use, common on these systems, should suffice to deal with VoIP security

You have heard about VOIP, but you have no idea what it is. Is this just another telephone carrier that has come along since the breakup of AT&T many years ago? Well, that is part of it, but this is another step further along as this system directly relies on the internet.

So, what is VOIP? It is Voice over Internet Protocol, a way of routing voice conversations using the internet or any other IP-based system as you continue using a regular telephone instrument. Okay, but how does it work? Can you be working on your computer and talk at the same time? Is there special equipment you need?

There are several companies that provide VOIP service. There is a cost savings because you have a single network to do everything-it carries both voice and data and on the same internet lines. If you have the right company that can carry both the voice and data lines together, there might be no additional cost to combine these two features.

The VOIP telephone system can help by automatically routing incoming telephone calls to your VOIP phone, regardless of whether or not you are connected to the network. You can take you phone with you on a trip and whenever you connect to the Internet you can accept incoming calls.

You can get free telephone numbers for use in some countries. People using this system can work anywhere as long as there is a sufficiently fast and stable Internet connection available to them. Like your other telephone system, you can usually get 3-way calling, call forwarding, automatic redial, and even caller ID.

So, is this system right for you? There are definitely advantages and as with all systems, some disadvantages. How do you choose? That depends and you should do some extensive research to make sure that the VOIP telephone system will work for you.

Well, you might actually be using a VOIP system at your office and not know it. The VOIP telephone systems have offered businesses high-powered telecommunications capabilities once available only to the largest, most expensive companies’ systems.

Today, advanced VOIP solutions enable all employees, whether they are down the hall or a thousand miles away, to respond rapidly to customers and business opportunities by allowing their phones and computers to integrate into one seamless system.

Check with your telecommunications people in your organization as they can tell you whether or not you are already using the system through work. They will also be very knowledgeable about the positive and negative components of the VOIP system and will probably be able and willing to talk to you extensively about their experiences with it. Remember, they are the people in your organization that must keep the computers and telephones up and operational for the company.

So, what do you think? Do you want to take the plunge and try the VOIP telephone system? Go ahead and take a chance if you think it will work for you. If it does not, you can always change back to a regular telephone.

With the advent of widespread broadband Internet connections, consumers are discovering what businesses have known for a while. Voice over IP telephony, or VoIP as it is known, can be a viable and cost effective alternative to the Plain Old Telephone System (POTS). As VoIP upstarts are popping up everywhere, most notably Vonage, Packet8 and Skype, even the big Internet Service Providers are offering voice over IP packages to their residential subscribers

Such features as caller ID, call forwarding, automatic redial, and even 3-way calling are standard on most VoIP packages, whereas many phone companies consider them add on’s and will charge you extra. But the real kicker is, if it is right for you and you pick the right Voice over IP solution, you should be able to reduce your phone bill by half or more.

How Does Voice over IP Work?

IP Telephony is a packet switching technology, as opposed to circuit switching as used by the PSTN (Public Switched Telephone Network). The PSTN method uses copper wires to physically connect one caller to another through a series of circuit switches, as illustrated by the switchboard operators of old.

In voice over IP, the analog voice is converted into digital packets that are routed through the internet, and in the case of one of the parties being on a PSTN connection, the packets are routed to the nearest local switching station and placed back on the PSTN. If both persons are using VoIP, then there is no reason to use the PSTN, and the entire conversation takes place over the Internet.

Needless to say, this is much more cost effective than using land lines for the entire distance. If a caller in New York uses VoIP to call a PSTN number in Seattle, the call doesn’t leave the internet until it reaches the switching station in Seattle, making it for all practical purposes, a local call.

The Drawbacks of Voice over IP Telephony

There are some points that one should seriously consider when thinking about dumping the POTS. VoIP generally requires a Broadband Internet connection, which in turn requires power. If a power outage should occur, you have no telephone service. Battery backups could solve this problem, but not on a long term basis. Internet Service Providers (ISP’s) also have a tendency to go down occasionally, though they are getting better all the time. Calls can be forwarded to your cell phone if your power is out, but in real disaster situation, even cell phones are not a perfect backup, as seen by Hurricane Katrina. Faxing over an IP network has proven to be problematic. Fax machines scan a document and convert the data into sounds, which don’t travel well over the internet. In IP telephony, much progress has been made on a standard called T.38, whose mission is to convert the fax sound into sendable data. Another option is iFax, the T.37 standard that sends faxes as an email attachment or a remote printout using the Internet Printing Protocol. Today, separate Fax lines can be added by most VoIP providers for an extra charge.

Emergency services such as 911 are also an issue with IP telephony. It is the nature of the Internet that tying a particular node to a geographic location is quite difficult, and street addresses are not easily routed to a nearby call center. In the U.S., the FCC has mandated that VoIP providers implement Enhanced 911 (E911). Providers are making progress by encouraging their customers to register a street address to their phone number, enabling them to route emergency calls to a nearby call center.

Voice over IP and Broadband Connections

While a broadband connection is not absolutely necessary, it is what makes VoIP shine. Many households are turning to DSL or cable modems for their internet connections, and wireless broadband WiFi hotspots are popping up everywhere.

The problem with DSL is that it is provided by telephone companies which for the most part require you to have a landline, pretty much defeating the purpose. Some regional Telco’s are starting to unbundle their DSL services by offering “naked DSL”, an Internet connection without the analog line on the local loop. When you think about it, there really doesn’t seem to be much motivation for the Telco’s to promote VoIP, as it would effectively be like cutting their revenues in half.

If your household has cable television, you more than likely can get broadband access through a cable modem. Most cable providers charge around $50 a month for broadband internet access, and for those who utilize the Internet often, a high speed internet connection is well worth the price. Some cable IPS’s offer residential Voice over IP for $40-$50 a month. Through the pure play VoIP companies like Vonage or Packet8, you can get VoIP for around $15-$25 a month, potentially eliminating the need for a land line at all.

Wireless networks also work great for VoIP, and are especially convenient if you travel a lot. Hotspots all over the world allow you to call anywhere using a WiFi VoIP phone. Internet phones come in all shapes and sizes with all kinds of bells and whistles. From a full business desk phone from Cisco, to phones indistinguishable from cell phones, even regular cell phones that are VoIP capable – new products and technologies are coming out every day to get you better connected for less.

Voice over IP telephony has come of age. If you have access to a broadband Internet connection, you could conceivably cut your phone bill by half or more, never pay long distance charges in the U.S. and Canada, and pay way less for International calls as low as 3 cents per minute. Sound quality is usually as good as a cell phone connection. To test you current broadband connection, visit http://www.TestYourVoip.com and download the java applet.
