Got Questions?

A PRI line is a telephone technology that allows for voice conversations. ISDN (Integrated Services Digital Network) is a telecommunications technology that allows voice, data, and video traffic to be sent over ordinary phone lines. PRI is an ISDN interface. Using multiplexing and de-multiplexing methods, a PRI line may carry numerous lines of speech and data as electrical impulses through copper cables. A PRI connection is required for a standard telecommunications operator to transport voice traffic. PRI telecom services allow two-way access between an ISDN-compliant PBX or Key System and the Public Switched Telephone Network (PSTN).


PRI stands for Primary Rate Interface.

A PRI is a voice-only connection used for phone communication. While PRI has certain scaling limits, it provides a higher-quality speech option than voice-over-IP. Using SIP, businesses may use their current Ethernet connection to provide phone services.

A PRI line is more secure than an analog line since it is far more difficult to extract them to monitor conversations, and it may also be more secure than a SIP line because communication may be routed through the public Internet.


PRI offers Thirty (30) channels.


The Quality of Service (QoS) of a PRI line is higher than that of an analog or SIP line. PRI connections have dedicated bandwidth that cannot be utilized for anything else.


A single PRI line can only handle 23 simultaneous calls; businesses that want more calling capacity must purchase additional PRI lines.
