Over the years, VoiP was a wide and also predominantly young audience now gradually accessible and with all its typical characteristics, including each with displayed the attendee’s presence “status”, so its current availability, increasingly familiar. VoiP applications for the business sector, however, failed at first, especially at the beginning but very noticeable loss of quality compared to ISDN, like the typical echo effects, transmission delays (with the famous “himself-in the word-fall”) or packet loss (with disturbing interruptions of language up to the incomprehensibility). VoiP private users that initially seemed reserved and not any time soon to gain real business relevance. The voice quality not comparable with the ISDN or “classic” telephony in General was easy over the years. Also seemed with the overall costs of national as well particularly for international calls as a result of deregulated markets the argument advanced in the Center cheaper phone calls with VoiP more and more to fade. CONVERGENCE provides important market advantages and even if modern VoiP need to shy away from in the meantime no qualitative comparison with ISDN more solutions, such as those from Microsoft and manufacturers other leading because of generally better bandwidth and now much better voice and compression algorithms, so in fact even today alone the argument of lower voice connections should be not really applicable for a complete – and therefore also quite cost – shift to VoiP technology. Rather, this aspect of ‘convergence’ must be considered now much more comprehensive: today not only to a cheaper alternative to ISDN telephony, but rather the integration of VoiP telephony into existing IT / database and telecommunications or in complete business process structures, involves so to reach this destination leading ultimately faster on relevant information efficiently to share and significantly improve overall the daily team collaboration and communication within the company, which then in turn important cost and competitive advantage generate can. It’s going to observable market consolidation so mission-critical aspects and significant cost savings through efficient communication as well as the creation of increasingly important competitive advantage through faster access to information and an overall significant acceleration of decision-making – particularly in difficult times. Microsoft used to do this, the concept of “collaboration” – so the ultimately much more efficient “cooperation” in the team – and the the “unified communications” (UC) as a next logical evolutionary step for the term established for some years of the “information be unified messaging”(UM): unified in a common Inbox messages, such as e-mail, voice-mail, fax, or SMS/MMS with ” modern unified communications infrastructure now extends to the “real-time communications”, so the cooperation communicating and working together in the team, the very significant especially in distributed, international structures efficiency and in turn can create competitive advantages!
