What is IP PBX System?
An IP PBX (private branch exchange) is a telephone switching system within an organization that switches calls between VoIP (voice-over-Internet Protocol or IP ) users using local lines. All users can also share a limited number of external lines. An IP PBX can switch calls between a VoIP user as well as between traditional telephone users, just like a conventional PBX. This abbreviation can be found in many texts, such as IP-PBX or IP/PBX.
Separate networks are required for data and voice communications with a traditional PBX. An IP PBX has converged voice and data networks, which is one of its main benefits. It allows Internet access as well as VoIP and traditional telephone communications to be made possible by one line per user. This allows for flexibility, which can be beneficial as the enterprise grows. It also helps to reduce long-term maintenance and operation costs. An IP PBX can be used in the same way as a traditional telephone system.
How does an IP PBX work?
IP PBX Phone Systems can place and receive calls over the Internet. It converts analog voice signals into digital. It then directs calls to a VoIP provider to handle the initiation and end of each call.
Session Initiation Protocol is the heart of IP-based voice services. This protocol is the standard for VoIP phone systems. SIP trunking is used to provide multiple voice channels for a PBX.
The inner side of a PBX is unchanged. As before, users can still call each other and check their voicemails. They can also set up call groups. It is by design.
A VoIP provider would provide credentials to one or more SIP trunking account accounts on the outside of a PBX. After authentication, incoming calls will be presented to your PBX for acceptance. Your SIP trunk can be used to automatically reach outside numbers.
The PBX determines whether calls are handled internally or transferred to the PSTN.
It is important to understand its limitations. But first, let us discuss the benefits of adding a VoIP gateway into your PBX.
