This blog will clarify the key differences between SIP trunking and VoIP to help you make an informed decision for your business.
What is VoIP (Voice over Internet Protocol)?
Voice over Internet Protocol (VoIP) is a technology that enables voice communication and multimedia sessions via the internet. Instead of using traditional phone lines, VoIP converts voice to digital signals and sends them via the internet. This method is inexpensive and includes services like as call forwarding, voicemail, and video conferencing.

- Flexibility: Can be used on various devices (phones, computers, tablets).
- Advanced Features: Includes call forwarding, auto-attendant, voicemail to email, and more.
What is SIP Trunking?
Session Initiation Protocol (SIP) Trunking is a service that enables businesses to use VoIP technology to connect to traditional phone networks. Instead of using physical phone lines, SIP trunking uses a virtual connection. This approach can significantly reduce costs and improve the reliability of your phone service.
Key Features of SIP Trunking:
- Integration: Connects VoIP systems with the PSTN.
- Cost Efficiency: Reduces costs associated with maintaining multiple phone lines.
- Reliability: Offers better call quality and reliability.

- SIP Trunking: A connection between VoIP systems and the traditional phone network. It allows the usage of VoIP services while keeping PSTN connectivity.
2. Implementation
- VoIP: Implemented directly on devices like phones, computers, or tablets using a VoIP service provider.
- SIP Trunking: Requires a SIP trunking provider and integration with an existing PBX (Private Branch Exchange) system.
3. Cost Structure
- VoIP: Generally has lower setup and operational costs, especially beneficial for small to medium-sized businesses.
- SIP Trunking: Can result in higher initial setup costs but offers significant long-term savings for businesses with high call volumes or multiple locations.
