What is the Difference between Pri Trunk & Sip Trunk


What is a PRI trunk?

A PRI trunk is a type of digital circuit that is used to carry voice and data traffic. PRI trunks are commonly used by businesses that have a high volume of long-distance or international calls. PRI trunks can also be used to connect PBX systems to the public switched telephone network (PSTN). SIP trunk is a type of VoIP (Voice over IP) that uses the Session Initiation Protocol to connect to the PSTN. SIP trunk can provide significant cost savings for businesses that make a lot of long-distance or international calls. SIP trunk can also provide additional features and flexibility that are not available with PRI trunks.

What is SIP trunk?

If you've been researching VoIP solutions for your business, you've probably come across the terms "PRI trunk" and "SIP trunk." But what's the difference between the two? A PRI trunk is a physical connection between your PBX and the telephone company's network. A SIP trunk is a virtual connection that uses the Internet instead of a physical connection. SIP trunk offers many advantages over PRI trunk, including lower costs, flexibility, and scalability.

Difference Between SIP and PRI trunk?

There are a few key differences between SIP (Session Initiation Protocol) trunk and PRI (Primary Rate Interface) trunk. SIP trunk uses a packet-based connection, while PRI trunk uses a circuit-based connection. SIP trunk is typically less expensive than PRI trunk, since it uses an existing IP network and doesn't require the installation of special equipment. SIP trunk can be used with a variety of IP PBX systems, while PRI trunk is typically used with a traditional PBX system. SIP trunk can be more flexible than PRI trunk, since it can support multiple concurrent calls and can be easily scaled up or down as needed.

What are the Benefits of a SIP Trunk?


A PRI trunk is a physical line that connects your PBX to the PSTN. A SIP trunk is a virtual line that uses the IP network to connect your PBX to the PSTN. The benefits of a SIP trunk are many. The biggest benefit is that it is much less expensive than a PRI trunk. A SIP trunk can also be easily configured to work with almost any PBX. Additionally, SIP trunks typically provide more features than PRI trunks, such as the ability to easily scale up or down the number of channels as needed.
