Choosing between PRI and SIP?

What You Need to Know

Your phone system is essential to the operation of your business. Whether you’re interfacing between teams, working remotely, or communicating with clients, your phone system needs to be reliable while providing excellent sound quality. If you are considering upgrading or replacing your system, there are certain factors you should ensure that you consider. First, however, let’s review the major kinds of phone systems.

What are PRI systems?

PRI, or Primary Rate Interface, is a method of digital connection that allows for multiple voice, data, or video transmission to occur simultaneously. PRI systems achieve this through physical lines or circuits. As you might have guessed, this technology has been around for some time (several decades, in fact), and is limited to 23 channels for data or voice per each physical circuit. Each of these circuits - a cable containing two pairs of copper wires - requires on-site installation.

What are SIP systems?

In a SIP (Session Initiated Protocol) system, communications are sent over the internet. These communications can include voice calls, video chats, data transfers, or instant messages. SIP systems do not technically require a telephone network at all, as any internet-capable device can process SIP communications. Each communication channel in a SIP system is called a “trunk.”
What are the advantages of SIP systems?
SIP providers give businesses much greater flexibility. For example, if a business would like to add a new line or troubleshoot any issues, their SIP provider can assist virtually with either request. SIP trunking is also much cheaper and easier to manage than PRI methods because there is no necessary hardware and because systems can be configured through easy-to-access administration portals. On top of that, SIP systems can be integrated with PBX phone systems to achieve optimal call quality and security.

Where do PBX phone systems come in?

Many businesses are upgrading to SIP systems that integrate with PBX phone technology. Essentially, a PBX (or private branch exchange) operates a company’s internal phone network, managing auto attendants, voicemail, recorded messages, and phone extensions for every team member. When integrated with SIP systems, calls can be made using Voice over Internet Protocol (VoIP) technology, freeing businesses from their local telephone companies and helping them save on costs.
