In this documentation, we will introduce a few key terms you will encounter while integrating SIP with Vapi through SIP trunking.
SIP is a signaling protocol used to initiate, manage, and terminate real-time communication sessions over IP networks, such as voice and video calls. It is essential for tasks like call setup, modification, and termination, enabling devices to connect and communicate efficiently within the network.
Call Termination refers to the process of routing outbound calls from one network to another, ensuring that calls reach their intended recipients. This is a critical component in completing calls across different telecommunication networks. Termination involves carrier agreements, quality of service considerations, and associated costs, particularly for international calls.
Call Origination is the process of receiving inbound calls on a network. This involves assigning and managing phone numbers, allowing users to receive calls from the Public Switched Telephone Network (PSTN) or other IP-based networks. Origination can include local or toll-free numbers, with calls routed to the recipient within the network or passed on for further processing.
Understanding these terms will help you navigate the process of integrating SIP with Vapi through SIP trunking, ensuring effective communication across networks.
