SIP Trunks Insights

What is SIP Trunks?

SIP Trunks are virtual phone lines that use the Session Initiation Protocol (SIP) to enable voice communication over the internet. They replace traditional physical phone lines (PSTN) and are commonly used by businesses to connect their PBX (Private Branch Exchange) to an Internet Telephony Service Provider (ITSP), reducing costs and offering greater flexibility and scalability.
