SIP Trunking (Session Initiation Protocol Trunking) is a technology that enables businesses to make and receive voice calls over the internet instead of traditional PSTN or ISDN lines.
SIP trunks connect your on-premise or cloud PBX directly to a VoIP provider, allowing scalable, flexible, and cost-effective communication.
Calls are initiated using SIP signaling and transmitted over IP networks. Media streams use RTP, ensuring high-quality voice delivery.
Enterprises use SIP Trunking for unified communications, contact centers, remote offices, and international expansion.
