Session Initiation Protocol (SIP) trunking is a technology that makes making and receiving calls through an existing Internet connection possible. It uses Voice over Internet Protocol (VoIP) system, which significantly reduces the cost of making calls through Public Switched Telephone Network (PSTN).
The technology is currently being used by thousands of businesses around the world because of the benefits it offers. These include:
Cheaper calls – SIP trunk connection allows you to call anybody from other parts of the world without incurring international phone charges. With this technology, making international calls is like dialing a local number.
A simple infrastructure – With SIP trunking, you will not need to install separate circuits for voice and data. This is because the technology relies on a data network for all types of communications.
Flexibility – SIP trunking can easily address the changing needs of growing companies as it allows users to easily add channels once they start to experience increased call volume.
Security – The network is securely protected against threat.
Reliability – Digital circuits are more reliable than PSTN networks and require lower levels of maintenance while providing a higher quality of calls.
