I started to do research on the various proposals that are on the market for IP telephony or Internet (VoIP) and its importance to save costs on phone calls in the business and public administration, and the first search on Technorati I found several updated articles and writings on this subject and decided to abandon this effort for the sake of a good hypertext link. In comparison of IP telephone systems (VoIP) make a deep comparative description of the value proposition of the leading VoIP systems including the form of service, prices, savings and advantages of the following:
* Skype (VoIP + video)
* Vonage (VoIP + video conferencing, transmission of information such as fax, email, etc. And no charge for calls to mobile and fixed parts)
* Netzerovoice (VoIP + video conferencing, transmission of information such as fax, email, etc.).
* 4gPhone (VoIP + video conferencing, transmission of information such as fax, email, etc.).
* Gizmo (VoIP + maps or other services integrated into web 2.0)
* Dialpad (low prices for VoIP + telephony)
* Voiceeclipse (VoIP + package includes installation and terminals)
* Skypho (VoIP + package includes installation and terminals)
- I also add:
* Yahoo Messenger with Voice (Calls PC-to-PC + videoconferencing + service integration at all Yahoo!)
* Peoplecall (VoIP – PC-to-Phone and SMS)
The rise of IP telephony in the enterprise has created the need for access systems more productive, flexible and ergonomic, and IP phones (such as Linksys CIT20 shown here above) are found extraordiaria demand. Cisco, for example, has more than six million units of IP phones sold worldwide and has more than 30,000 customers worldwide of which over 80 have more than 5,000 IP phones each in their facilities. Currently almost 12,000 traditional phones replaced a day, according to the “Voice Market Shares Business in the Third Quarter of 2005″ Synergy Research Group.
Regarding the future of IP telephony – VoIP in public administration, which clearly does not arrive soon, I recommend this entry in k-government.
