Description: QSIG is a signaling protocol used for communication between private branch exchanges (PBX). This protocol allows the interconnection of different telephone systems, facilitating call management and information transmission between them. QSIG is based on the ISDN (Integrated Services Digital Network) standard, enabling it to leverage digital transmission capabilities for more efficient and higher quality communication. Its main features include the ability to support multiple types of services, such as voice, data, and fax, as well as the possibility of establishing connections between different telecommunications equipment manufacturers. Additionally, QSIG allows the implementation of advanced functions such as call transfer, caller identification, and conference management, making it a valuable tool for businesses looking to optimize their communication infrastructure. Its relevance lies in its ability to integrate heterogeneous systems and improve interoperability between different telephone platforms, which is essential in business environments where multiple communication systems are used.
History: QSIG was developed in the 1990s as part of efforts to standardize communication between different telephone systems. Its creation was driven by the need to facilitate interoperability between equipment from different manufacturers, especially in business environments where multiple PBXs were used. Over the years, QSIG has evolved and adapted to new communication technologies, maintaining its relevance in the telecommunications field.
Uses: QSIG is primarily used in business environments to connect different telephone systems, allowing for efficient call management and data transmission. It is commonly employed in organizations that use multiple PBXs from different manufacturers, as it facilitates interoperability and system integration. Additionally, QSIG is used in IP telephony applications and in the implementation of unified communication solutions.
Examples: A practical example of QSIG is its use in a company that has multiple branches, each with its own PBX. Thanks to QSIG, these PBXs can communicate with each other, allowing employees to make internal calls at no additional cost. Another example is its implementation in unified communication systems, where voice, video, and data are integrated into a single platform.
