What is SIP trunking?
When selecting enterprise phone services, the decision usually comes down to SIP trunking vs PRI phone service. While both technologies connect users to the Public Switched Telephone Network (PSTN) through an on-premises PBX (Public Branch Exchange), there are significant pros and cons associated with each.
For those unfamiliar with SIP service, here’s a short primer on “What is SIP trunking?” that covers both the details of the technology, as well as its benefits and drawbacks.
What is SIP trunking phone service?
SIP stands for “Session Initiation Protocol”, a set of rules that establish how connections between two endpoints are initiated, managed and terminated on an IP-based network. SIP trunking uses Voice over Internet Protocol (VoIP) to route voice traffic through an enterprise’s data network rather than over telephone lines or physical connections to the PSTN.
What is SIP trunking’s biggest advantage?
Because SIP phone service requires no telephone lines or physical connections, it can significantly reduce operating costs and complexity while providing users with next generation collaboration features to increase productivity. SIP trunking enables employees to use tools like audio and video conferencing, unified messaging, soft phones, simultaneous ringing and presence to stay connected with colleagues and clients more easily.
What is SIP trunking’s most significant drawback?
SIP trunking may not deliver the quality or security of a PRI service, as traffic is often routed over the public Internet and may be subject to network interference, packet loss or jitter, as well as the security concerns associated with Internet traffic.
