SIP Trunking Insights

What is SIP Trunking?

SIP Trunking is a voice over IP (VoIP) technology that enables businesses to connect their private branch exchange (PBX) to the internet and the public switched telephone network (PSTN) using a SIP (Session Initiation Protocol) trunk. It replaces traditional phone lines (POTS or PRI) with a digital connection, offering flexibility, scalability, and cost savings. Businesses commonly use SIP Trunking to make and receive phone calls over the internet, integrating their voice communications with their data network.
