High-quality calls made over a primary rate interface are established much quicker due to their dedicated line structure. PRI environments allow for granular location information from a caller to be delivered to call centers.

This would include the caller's building address, the floor they're on, and subnets within that floor allowing for emergency responders to quickly and accurately locate the caller. SIP trunk carriers often don't provide this granular information. This would be a problem on a college campus for example. If someone called from a campus with SIP trunks, the center would see that the call is coming from the college campus but NOT what building the call is coming from, what floor, etc.

Every circuit will need a physical connection and hardware to terminate the connection. Due to this requirement, scaling your system up will mean installing additional hardware and new circuits. Primary rate interface is not going to be the solution that best meets the needs of every organization. PRI is great if you're a heavy user of telephony services and prioritize top-notch call quality.

Primary rate interfaces will provide you a quick connecting, secure, and reliable voice solution. This comes at the price of high upfront costs for the installation of fixed infrastructure and a potentially lengthy install period. The cost of one PRI line can be less than separate analog trunks.

ISDN also helps businesses simplify their telecommunications system. With the direct inward dialing DID feature, also called direct dial-in DDI in Europe, one PRI connection can handle local, long distance, voice, data, video conferencing and faxing, and all of those functions can be done simultaneously because they can be assigned to different channels.

DID also allows outsiders to call an extension directly instead of having to go through a PBX auto attendant. In addition to being able to assign individual channels to a specific user or purpose, a business can have one main number for several channels. If multiple people call at the same time, the calls can land in any channel that is free, instead of requiring the user to dial another number manually when one line is busy. SIP trunking, the technology that supports voice over internet protocol VoIP , may be a better choice for businesses that are looking to upgrade their traditional phone infrastructure or scale rapidly.

SIP trunking is sold on demand. ATM networks are connection oriented networks for cell relay that supports voice, video and data communications. Category: technology and computing computer networking. What is replacing ISDN? Is ISDN still available?
