SIP Trunking frequently asked questions
SIP Trunking is a popular method for delivering voice and other communication services over the Internet using the Session Initiation Protocol (SIP). It replaces traditional telephone lines by connecting a company's Private Branch Exchange (PBX) to the Public Switched Telephone Network (PSTN) via the Internet.
SIP Trunking uses the Internet to transmit voice data, offering greater flexibility, scalability, and often reduced costs, whereas traditional phone lines rely on physical connections.
SIP Trunking offers several benefits, including cost savings, scalability, flexibility, improved call quality, and integration with other communication platforms.
SIP Trunking providers route emergency calls to the appropriate Public Safety Answering Point (PSAP) based on the caller's registered location. Keep in mind you must keep location information updated with your provider.
Security depends on the implementation. Using recognized encryption protocols, secure networks, and working with reputable providers can enhance the security of your SIP Trunking services.
Call quality is influenced by internet bandwidth, network stability, and Quality of Service (QoS) configurations. Working with a reputable provider with a robust network infrastructure is key to ensuring high-quality calls.
