Business Phone Systems: History of the Business Phone System

By Chavella Kelly
The telephone is a basic communication tool in business. In fact, it is quite common even for small and medium size enterprises to have their own PBX trunk. This business phone system provides local interoffice communication among geographically dispersed offices. Aside from that, it also routes long distance calling that is coursed through the local telecommunication company.

Converging Voice and Data

In the mid 90s, it was quite fashionable among IT strategists and planners to talk about the union of voice and data. For a while, this convergence only meant a physical aggregation of phone lines and data lines in one socket. People still needed to get a separate telephone and PC on their desktop. Over time, however, this evolved into a kind of hybrid interoperability between data and voice, rather than the true convergence promised in VoIP telephony.

The major telco grade business phone system suppliers were one in coming out with IP PBX machines that incorporate internet telephony features with traditional analog voice. At the turn of the 21st century, it was common to have conventional PBX systems upgraded with VoIP daughterboards to give them VoIP features. By 2005, digital VoIP PBX reached critical mass and started outselling traditional PBX machines. It was the turning point VoIP history. Today, nearly all PBX are digital with trunking features that allowed interoperability between conventional and VoIP business phones.

Features of a Modern Business Phone System

Today's business phone system have technological features such as IP-based video calls and teleconferencing, voicemail, dial-by-name directory calling from the desktop PC, auto attendance, auto-routing to cellphones, and interoperability between analog and VoIP phones, to mention just a few of the major features. Upgrading to accommodate more phone sets is another feature. The company may also opt to accommodate IP-based phone switching that comes with a full IP-based business phone environment as well.

Nothing exemplifies the modern business phone system than call centers. But these are more an integration of current conventional voice with digital features of a PC. The convergence between voice and data has yet to fully mature. Right now, most PBX systems used today are generally hybrids that combine conventional analog voice with digital VoIP features.

It will take a couple of more years-or maybe even an entire decade-for this to happen, and only if the major industry players will allow it. Doing this has a lot of advantages for corporate America's model of a business phone system. It can be expected, however, that it will be slow due to extensive changes required for the actual infrastructure.

Group Support For Sex Addiction Recovery Meets In Various Locations

By Nelda Powers The individual with a sexual addiction is dependent on excessive intercourse just as the alcoholic is dependent on drinking. Alcoholics Anonymous is an organization that holds meetings to help alcoholics. There is similar group support for sex addiction in many locations. The sexual addict is not the same as the sexual deviant. That individual seeks practices that are abnormal. They are often against the law as well. The sex addict is drawn to what are defined as normal sexual practices. He or she is a nonparaphilic sexual addict. The sexual deviant may be an exhibitionist or a pedophile, which are paraphilic sexual addictions. An addiction can be to internet porn as well as to in-person sexual encounters. It can be a daily or twice daily obsession, however, the actual sex acts fall within what is considered normal. It is only the frequency that is not. It is the inability to limit the frequency that is problematic. The symptoms of an addiction include the...
