Voice over IP Truth and Fiction I draw my opinions after running my own IT support and business equipment company for over 25 years.After I sold that company I spent many years in both the IT and Telecommunications arenas. I have been certified to sell Cisco Call Manager and have successfully sold and implemented both premise based and hosted IP telephone solutions to businesses large and small.The term VoIP stands for "Voice over Internet Protocol" and it encompasses a wide spectrum of voice communications solutions. Virtually every phone carrier in the country uses VoIP somewhere in there backbone to reduce the cost of transmitting voice from one point to the other.The telecommunications marketplace has been dominated for decades by the carriers, AT&T;, Southwestern Bell and Windstream etc.; the phone manufacturers; Avaya, Nortel, NEC etc. and the dealers who do the installation and support who refer to themselves as "interconnects."Arguably, the greatest advancement in productivity to take place in this industry was voice mail and that was nearly 2 decades ago.Over that same period of time, Wireless technology (cell phones) has gone frombriefcasesized portable phones with huge batteries that cost several hundred dollars each with extremely expensive minutes that only the most successful executives could afford to free phone with a plethora of features along with very cheap minutes by comparison. They have made pocket size cell phones with cameras, voice mail, text mail and e-mail available to virtually everybody.Business class telephone service, on the other hand, has done little to advance in that same time frame. The "interconnects" business relies upon their customers' need for services. The manufacturers rely on systems that are built to become obsolete so they can keep the factory open. And the carriers continue to gouge their customers even though deregulation was supposed to put an end to that. The truth is that the carriers have a monopoly on all local service in their area and have operated as any monopoly would.When Cisco brought this technology to the forefront at Fortune 1000 companies they explained how companies with multiple locations could bypass their local carrier(s) and talk inter-company over the company's internal network using VoIP. They also were able to route long distance calls using the least cost route through their network. They have dominated that marketplace ever since.This technology turned voice into data and the telecommunications world has not been the same since.Once voice became data, the pace of enhancements parallelled that of the computer world rather than the telecom world. Over the past 10 years reliable VoIP solutions have been implemented in businesses of all sizes replacing the obsolete triumvirate of carrier, Mfg and interconnect.Since voice can now be carried over the Internet, the local phone company can be taken out of the loop. Before VoIP, phone systems were proprietary, limiting your options for repair and replacement. If you wished to change phone switches, you had to buy new phones. That was a good idea for the manufacturer and interconnect but the customer was held captive.So who do companies call to obtain information about VoIP? Typically, they will call the local Interconnect who sold them there last phone system because they have had a long and happy relationship with them. Unfortunately, this is akin to asking the wolf to guard the hen house.Most Interconnects are telecommunications people not IT people, regardless of what they may claim. Replacing an analog phone system with a VoIP system would drastically reduce their revenue stream for service and support. The open architecture of true IP phones eliminates the need for expensive service agreements. Many Interconnects will portend that their "digital" phone systems are IP phones but this is not true. Those digital phones are still proprietary technology running over old phone company architecture. They simply use their proprietary digital technology to connect to the carrier's old wires. They can connect to remote locations using a company's network but, in most instances, that remote location has to buy a separate phone system to operate their phones.When asked, the typical Interconnect will say that VoIP doesn't work, that it is unreliable and that your phones go down when the Internet goes down. That is usually all that someone needs to hear and they spend their good money investing in decades old technology.The truth is that the Internet was created by the Military to provide a more dependable communications infrastructure in the event of a nuclear attack. The Internet does not go down.On the other hand, how many times do you hear radio and TV instructions to call neighboring police and fire departments because their phone lines are down?Of course your link to the Internet could go down. Your router could go bad. Your cable or T1 connection could be cut. However you face the same risk with traditional phone systems. Your phone switch and associated line cards can fail and your phone lines can be cut just as easily if not more.The quality of the voice transmitted over VoIP can be far better than traditional phone solutions. High Definition voice is available for VoIP and it is far clearer than anything available under current telecom technology.There are a host of different solutions that can claim to be VoIP. Premise based IP PBX solutions, like the Cisco solution, can implement VoiP within a company. However, many IP PBX vendors liked the model of the older phone manufacturers and try to keep their solutions proprietary with costly implementation and continuing support costs. There are open-sourc IP PBX solutions available based upon a platform called Asterisk. This Linux based program offers more features than most companies could ever use but, if you are not careful, you may end up without any support options. Make sure if you choose this option that you choose a local company that provides a turn-key supported Asterisk solution,The traditional world of Telecom has offered a solution called Centrex for many years. This option offered the functionality of the phone system from the Carrier which required a smaller investment in phone hardware. However, since it cut into the profits that the Interconnects were making on the hardware it never reached its market potential. Carriers even offered higher commissions on Centrex line to Interconnects. This ended up with clients getting Centrex lines to run their expensive phone systems. Who were the winners here?In the VoIP world there are numerous IP Dial tone providers. These are the people who compete with the Carriers. They bypass the local carrier and typically can save 50% or more on a company's local and long distance. More importantly, they are not governed by the same set of rules as traditional carriers. This means that, in most cases, they can put all of your telephone numbers with one provider. This eliminates the cost of call forwarding numbers from "FX" (foreign exchange numbers) or any cost to inter company calls.So any company who is looking to save money on their phone bills or upgrade old fashioned phone systems with a more productivity enhancing system should, at least, investigate VoIP with an open mind.There are many ways to create appropriate phone solutions. You do not, necessarily, have to replace a perfectly good phone system to take advantage of VoIP. You also do not need to run an IP phone system over a VoIP provider.
