Best sip trunk providers8/22/2023 ![]() ![]() SIP connects the private branch exchange hardware to the internet. This system enables users to communicate both externally and internally through various communication media like ISDN and VoIP. This tremendous shift in the delivery of communication from the industrial revolution to the information age, which is also known as the digital age, have been made possible through innovations and inventions that have improved the delivery of vast amounts of information by the use of computers and telephones over a very short period of time.įor SIP trunking to work, there has to be an IP-enabled private branch exchange or PBX system. This technological revolution has made communication much faster, cheaper and easier to execute than it was during the industrial revolution. The technological evolution as relates to communication in the latter part of the 20th Century has impacted businesses and interpersonal communications in more ways than people could ever imagine. The introduction of DSL and cable towards the millennium improved internet speeds tremendously and led to greater demand for VoIP over traditional analog lines. This creation formed the basis which SIP trunking would ultimately operate.įurther developments in telephony and the refinement of IP PBX systems and VoIP gateways meant that SIP could support improved voicemail features like voicemail to email. The year 1996 was the defining moment in the history of modern telephony when Mark Handley, a computer expert and others including Eve Schooler, Henning Schulzrinne and Jonathan Rosenberg designed the Session Initiation Protocol. VoIP technology had previously not been made available to individuals and businesses until the year 1995 when the initial VoIP software was crafted for home and personal computers. VoIP communication was made prominent during the 90s but it was first used in the year 1974 when it was piloted through ARPANET. The history of SIP is better understood in retrospect by tracing the invention of the telephone and subsequent changes in telephony. It goes without saying that the telephone is part and parcel of SIP. ![]() Without the telephone, VoIP and SIP would be virtually unheard of. SIP Trunking relies on the use of a telephone or an analog phone line. Long distance call fees are essentially eliminated. SIP calling may not be free but is relatively cheaper than the use of landlines for long distance calls. Their capacities to deliver the service is what defines the difference between the two. Simply put, SIP trunking and Voice Over Internet Protocol technologies are one and the same thing. All that is needed for SIP trunking is an internet connection, preferably a Virtual LAN that is meant for SIP trunk calls only. SIP trunking on the other hand uses the internet to send unified communications which include integrated services like single number reach and extension mobility, voice and instant messaging. These signals are analog and mostly transmit voice communications. Signals are carried along the switches through electrical wires. Traditional telephone systems rely on networks which are operated by switches. To understand how SIP trunking works requires a look at traditional telephony which includes landlines. The elements of a call that SIP supports include instant messaging, video distribution, video and call conferencing, voice calls and online faxing. This is a signaling system that enables electronic devices to communicate through VoIP by managing the elements of a call. The acronym SIP stands for Session Initiation Protocol. ![]()
