Choosing between SIP Trunking and PRI

Many businesses are now switching to SIP trunking systems vs. PRI. While the purpose of either system is to help employees make and receive calls easily, knowing how things work makes transitioning easier.

How the systems work

PRI is a technology which has been in use for nearly five decades. This interface has multiple lines that carry voice and data over copper lines. It requires signing up with a telecom company to get cabling and equipment so that information can be transmitted. A major advantage is that companies don’t need Internet lines to make or receive calls.

SIP trunking, on the other hand, is a method which supports VoIP calls using the Internet. It supports video conferences, data transmission, and many more. This is a great alternative to PRI, as there is no need for bulky equipment or long-term contracts. It is also cheaper, as it can be bought on an as-needed-capacity. One way to use both systems is to have a hybrid phone system that offers both PRI and SIP trunking.

Choosing between PRI and SIP trunking

These are competing technologies, and each offers distinct advantages. Some businesses choose SIP because it offers cost savings and reliability, as well as promotes improved collaboration. Some others choose a hybrid approach so that they can use legacy technologies.

Here are the factors that influence business owners’ decision:

– Cost: Many companies find that SIP is cheaper to implement and operate than PRI. Organizations who want to scale their systems find SIP more attractive to work with. PRI works well for small businesses that don’t need advanced features.
– Information security: While PRI is considered more secure, tapping and intercepting information is not very difficult. On the flip side, SIP trunking requires technical knowledge to configure and implement. For those who don’t have IT security, public connectivity can pose risks.
– Flexibility: In the SIP trunking vs. PRI debate, SIP wins because it is flexible and scalable. PRI requires the purchase of additional capacity. SIP can be implemented right away; whereas, there is a need to wait for PRI capacity.
– Reliability: Because PRI is heavily dependent on equipment, it is easy to lose connectivity if the infrastructure is old or the weather is too harsh. SIP is more reliable, as fiber optic networks provide the basis for connectivity.

Your choice will depend on your organization’s needs. For those who want quick connectivity, cost savings, and agility, SIP trunking is the best choice. PRI works better for small businesses that don’t require the features offered by SIP technology.
