What is the most significant advantage of a PRI line?

A PRI line has a better Quality of Service (QoS) than an analogue or SIP line. PRI connections have dedicated bandwidth that can't be used for anything else.

What is the most significant drawback of a PRI line?

A single PRI line can only take 23 simultaneous calls; businesses that need higher calling capacity will need to buy extra PRI lines.

What is the scalability of a PRI line?

Scaling a PRI trunking is more difficult than scaling SIP trunking due to the ease with which SIP trunking can be scaled. Adding a PRI line to accommodate more voice traffic necessitates infrastructure changes that could take weeks to complete.

What is a PRI Line?

A PRI line is a voice-communications-supporting telephone technology. ISDN (Integrated Services Digital Network) is a telecommunications standard that allows regular phone lines to transmit voice, data, and video traffic. PRI is a common interface of ISDN. A PRI line can send many lines of voice and data as electrical signals over copper wire using multiplexing and de-multiplexing technologies. A traditional telecoms provider must route voice traffic on a PRI connection.

A PRI line is more secure than an analogue line since that is far harder to retrieve them to monitor conversations, and it can also be more secure than a SIP line because traffic may be routed across the public Internet.

What is the difference between SIP and PRI?

A PRI is a dedicated voice-only connection for phone transmission. While PRI has some limitations in terms of scalability, it offers a higher-quality speech alternative than voice-over-IP. Businesses can leverage their existing Ethernet connection as a voice service with SIP.
