SIP Trunking.1611854698

SIP Trunking is the process of linking a group of devices together in a compact manner via a high speed Internet connection. SIP, as it is commonly referred to, is an acronym for session initiation protocol, which enables a caller to initiate and terminate phone calls using a unique number called an IP address. SIP Trunking is the technology that makes this possible. SIP Trunking allows users to use their Internet connections to connect to their phone service provider’s telephone system, where they can then dial telephone numbers dialed using a telephone keypad. SIP is also useful for connecting a computer to a telephone system.

SIP Trunking allows voice data to be transmitted over IP networks so that various users can connect to voice data as if they were making phone calls over the same network as the IP network. SIP Trunking is usually utilized in conjunction with Voice Over IP (VOIP), which is voice communication over the Internet. SIP is used in situations where there is an appropriate bandwidth available and Internet connection speeds are sufficient enough for voice data to be transmitted without delays.

In the past, SIP trunks required to be installed between two different Internet lines. Today, however, new developments have made it possible for SIP trunks to be installed within a single broadband Internet connection. In addition, SIP trunks can be installed within an existing PBX phone line by converting an analog voice signal into digital data using a digital telephone adapter (DTA). This conversion is referred to as digital to analog converters (DCA).
