About UMS (uniied Message Service)

Communication in many fields is more dependent on computers and computer networks. For example, many companies and subsidiaries use the Central Fax solution. The fax server solution supports both fax, email, and voice mail to convert and connect different messages through one server. This kind of development is called the integrated message system-UMS. With the rapid development of information technology, the history of "waiting for news" is gone forever. Due to travel and other "On Road" reasons, the remote access market changes cannot be understood in a timely manner to communicate with customers, this often leads to competition against orders and misses business opportunities.

About VoIP (Voice Over IP)

IP speech refers to a technology that transfers standard telephone services over an IP-based data network. The deployment of VoIP further expands the concept of an integrated messaging system. On the one hand, this solution enables voice relay to connect to the ubiquitous IP terminal devices, catering to the trend of voice-to-Data Network migration, making it more convenient. On the other hand, the various features of Internet telephony will easily integrate integrated messaging solutions, even the entire telephone system.

The main advantages of VoIP are:

Bandwidth efficiency: the combination of voice and data can make full use of existing data bandwidth resources. In analog telephone networks, voice is transmitted over a 64 Kbps TDM channel at a frequency of kHz, which wastes other bandwidth resources and uses advanced data/mode conversion technology, it is sufficient to transmit a single voice at a rate of 5.3 to 8/12 Kbps to ensure the quality of the call. In this way, voices can be transmitted simultaneously on a 64 Kbps line using a data cable, therefore, the bandwidth utilization efficiency will be greatly improved.

Reducing telephone usage fees: VoIP can use existing data networks, such as the Internet of the international network, or internal networks of enterprises, to send local and long-distance calls, you do not need to pay for each call. At the same time, the remaining bandwidth for voice transmission can also be used to transmit other data. This method is more effective when using an existing data network to send long-distance calls. Software PBXPrivate Branch Exchange group switch): the VoIP PBX technology is software-based. This makes it easier to expand, upgrade, and maintain vswitches than traditional hardware group switches.

About DIVA server card and Voice Gateway
