IP-PABX stands for Internet Protocol Private Automatic Branch Exchange. It is a telephony system that uses internet protocol (IP) networks to manage and route voice calls within an organization or company. PABX (also known as PBX) refers to Private Automatic Branch Exchange, which traditionally used circuit-switched networks to handle internal telephone calls within an organization.
The IP-PABX system uses Voice over Internet Protocol (VoIP) technology to transmit voice communications over data networks, such as the internet or a local area network (LAN). By doing so, it leverages the benefits of IP-based networks, including cost savings, scalability, and integration with other data services.
Call Routing: The system can route calls between internal extensions and can also handle external calls by connecting to the public switched telephone network (PSTN) through VoIP gateways.
Unified Communications: Integration with various communication channels, such as voice, video, instant messaging, and email, providing a unified experience for users.
Extension Mobility: Users can log in from any phone within the organization and access their personalized settings.
Voicemail: Voice messages can be recorded and stored for users who are not available to take calls.
Auto Attendant: An automated menu system that allows callers to be directed to specific departments or extensions without human intervention.
Conference Calling: Support for multi-party audio conferences.
Call Recording: The ability to record and store calls for various purposes, such as training or compliance.
Scalability: IP-PABX systems are generally more scalable than traditional PBX systems, making it easier to add or remove extensions as the organization grows or changes.
Cost Savings: Since the system uses VoIP technology, it can reduce long-distance call costs and simplify maintenance.
Remote Access: Users can access the IP-PABX system from remote locations, enabling flexible work arrangements
