What is SIP Trunking?
The term “SIP Trunking” is probably quite a familiar term to anyone who works within or is an enthusiast of the field of Voice of IP (VoIP) solutions. Until the late 2010s, the term was rarely used, but its importance was steadily increasing.
Basically SIP Trunking is a technique where by an IP based phone system can manage numerous telephone numbers from one individual account.
The classical SIP method is characterised in that each end user device for each number requires its own account. In contrast, SIP Trunking makes it possible, to manage multiple extension numbers via one account.
Since the ISDN shutdown in many countries, the transition to SIP and SIP trunking has seen companies and organisations around the world adopting SIP trunking services and reaping numerous benefits from lower costs to greater flexibility and scalability as employees can now be reached on the same number, on multiple devices without any complex call forwarding etc.
