Analog Lines are 100+ Year Old Technology!
Analog Telephone Lines, also called Plain old telephone service (POTS) is voice-grade telephone service employing analog signal transmission over copper loops. POTS was the standard service offering from telephone companies from 1876 until 1988
POTS remains the basic form of residential and small business service connection to the telephone network in many parts of the world. The term reflects the technology that has been available since the introduction of the public telephone system in the late 19th century, in a form mostly unchanged despite the introduction of Touch-Tone dialing, electronic telephone exchanges and fiber-optic communication into the public switched telephone network (PSTN).
PRI’s are 20+ Year Old Technology!
The Primary Rate Interface (PRI) was first defined in 1988 and is still popular today with traditional service providers. PRI used to be the standard for providing telecommunication services to offices. It is based on the T-carrier (T1) line in the US.
Current Technology!
Session Initiation Protocol (SIP) trunking has been commercially available since the early 2000’s. SIP trunking is a Voice over Internet Protocol (VoIP) standard by which Cloud service providers deliver telephone services and unified communications to customers equipped with SIP capable telephone systems. (IP-PBX)
The architecture of SIP trunking provides a partitioning of the Unified Communications network into two different domains of expertise:
Private Domain: a VoIP solution created on the customer’s network.
Public Domain: a VoIP access solution to the Public Switched Telephone Network (PSTN) in the Cloud
The interconnection between the two domains must occur through a SIP trunk.
