	VOIP system can successfully compact telephone voice data less than 10Kbps, and transfer the shortly by Internet / Intranet system. Then the leased lines have been used to bypass the phone charge for long distance calls. Also, our VOIP system support several different standardized voice compression algorithms, such as G.711/G.723.1/G.729A are implemented.

	VOIP utilizes the interaction of voice message to assist users more easily for data entry, such as user ID, password, telephone number, computer IP...etc. It also helps the users to understand the status of system condition.

Once a broad understanding of IP technology has been established, it is important to consider the details required of a successful operating system.

VOIP technology, as with all telecommunications technology, is governed by sets of standards that have been established by the International Telecommunications Union. For VOIP, H.323 is the most widely supported protocol, followed by Session Initiation Protocol (SIP) and Media Gateway Control Protocol (MGCP). The above standards representing a "common ground" between systems, making VOIP system compatible or support different relative existing systems for communication, conference calling, and virtual meeting applications. (e.g. NetMeeting)


	The greater advantage of our VOIP system is its can seamlessly compatible with most of PABX communication system without any additional hardware component, integrate with all forms of office communication and transfer any information to any member or branch at any time for improving the capacity and productivity.

	Our system can be automatically connected with a designed VOIP gateway by simply entering the preset "Hot-keys". The users are not necessarily to find out the corresponding IP every time before dialing, more user-friendly design.
