the benefits of a pri are REPLETE

PRI (Primary Rate Interface) is a voice technology that has been widely-used since the early 1980′s. It is an interface standard used on an ISDN (Integrated Services Digital Network) to deliver multiple lines of voice and data into a business’s exiting PBX via one physical line, called a circuit. PRI is a high-capacity service carried on T1 trunk lines between telecommunications central offices and your location.

Most businesses have their PRI circuits in the form of T1 or fractional T1 lines. A T1 line carries voice and data via 24 digital channels.

Physical hardware is not always old school

This technology is sometimes considered “old-school” telephony by virtue of its physical hardware which often requires servicing from a telecommunications company for deploying, upgrading and troubleshooting.  The benefit of this type of circuit are that its often touted as the more secure telecommunications method as traffic travels through a private telephone network.

It’s not uncommon for businesses to have 50 DID numbers on 1 PRI Circuit. In other words, your business can have 50 different phone numbers, 1 for each employee of the company, all coming across a single PRI Circuit. As long as you don’t have more than 23 people on a call at the same time, this is a perfectly viable option.

high quality service

PRI circuits always have a guaranteed amount of bandwidth set aside for each call that cannot be used for any other purpose thus ensuring a high level quality of service.  Please speak with a representative at Vive Communications to determine if a PRI is the right fit for your company.

Alternatives to PRI

Since PRIs provide blocks of 23 channels, there isn’t much room for flexible scalability. In addition, because PRIs are Circuit Switched, it’s sometimes a hassle once your company grows to a certain point; gaining multiple locations or a large number of employees. you need. 

PRI circuits also don’t make sense for very small companies with 1 to 5 employees, since you’re purchasing 23 call channels for only 5 people.

The main alternatives to PRI Circuits are:

  • Analog POTS Lines: these are just like the old land-line you would get at your house, 1 number for 1 dial tone and 1 phone call
  • Dynamic Integrated Services: although not as commonly used, since data requirements are much higher now, some providers are able to take an existing PRI circuit over a T1 and transmit data with it as well.
  • SIP Trunking: This is a newer method of voice transmission that uses your existing data connection, and SIP capable PBX, to send and receive phone calls
  • Hosted VoIP: This is very similar to SIP Trunking, except that you don’t use a PBX in your office. Instead the PBX is hosted in the “Cloud” by a service provider. You get all of the features of a traditional PBX, without the expensive hardware.
