What Is SIP Trunking?
SIP trunking, or Session Initiation Protocol trunking, is a method that enables businesses to make and receive calls over the internet rather than using traditional phone lines (PSTN). Instead of physical wires, SIP trunks use VoIP (Voice over Internet Protocol) to connect your business phone system to the public telephone network through the cloud.
SIP trunking replaces bulky hardware with flexible, internet-based calling that’s cheaper, scalable, and perfect for modern communication needs.
Why It Matters:
- Cost Savings: No need to pay for separate voice and data lines.
- Scalability: Add or remove channels without physical upgrades.
- Cloud Integration: Works seamlessly with cloud-based systems like Telerain’s Omnichannel Contact Center Software.
