It is said that the SIP trunking industry has taken a toll on the current dynamics of industries, companies, and enterprises. Also, it is said that SIP trunking has set foot on the world which works well for home-based businesses and other small scaled businesses. According to research and studies, it has grown 67% from 45% in the recent past which leaves us in predicting core value, dynamics, and other essentials. Most of us, however, are unaware of complete dynamics, core value, and other essentials. Here, in this article, we are about to discuss every bit.

SIP Trunking – What it is? 

It is an abbreviation of the “Session Initiation Protocol”. The main function of SIP trunking is to bridge the gap between internet communications; letting people send and receive messages, could be either voice or text. Also, it facilitates other types of unified communication that are carried out through the internet.

SIP trunking is workable with the help of a PBX, also known as “Private Branch Exchange”. It replaces conventional calling through telephone lines which are technically called “Primary Rate Interface). In recent past telephones were the only means of communication, a reliable means that transmitted voice signals.

PSTN (Public Switched Telephone Network) used to carry telephone calls and mostly had copper phone lines that were connected to the telephone sets. What is PSTN? It is a network of switches that transfers circuit. In order to connect two points to complete the process of calling, it always needs some physical connection – phone sets. SIP trunking is, therefore, a virtual phone which doesn’t need a telephone set; communication between two or more individuals is carried out via the internet.

SIP Trunking – Association with SIP Channels 

SIP trunk chains with several SIP channels (SIP channel is equal to one outgoing or incoming call). Since it holds an array of channels, users don’t need to buy more than one SIP trunk service at a time because it can place and receive an unlimited number of calls. However, the determination of channels required depends on the number of business calls one needs to do every time.

SIP and VoIP – Difference

Voice Over Internet Protocol (VoIP) is interchangeable with SIP. However, it cannot be the same as they have some dissimilarities too. VoIP, just like SIP entertains any call that is placed on the internet. It has a group of phone calling protocols in the world of technology. SIP is one of the many types or examples of the protocols. Nevertheless, SIP is the most important one for a reason – it enables VoIP to function.

Call Quality and Levels of Carriers 

Reliance on business communication systems on quality stands still. The quality, however, has to be the same, optimum and excellent, for both audio and video calls. Tier 1 carriers are needed to connect with the internet’s best quality calls. It means that to avoid distortion in the line and to sound better than calls on the telephone set, there is always a need to keep a check on the network which is used (this has to be checked by the SIP provider).

Quality of Service and Router Setting 

QoS or quality of service is based on the router’s setting. That actually reveals the quality of network which should be preferred to make a voice call over additional data traffic. Although a little delay in receiving signals can never be felt; but it definitely causes disorder in the calls. When QoS is enabled, it makes sure that the quality of audio will remains high. This quality has to be maintained through the sharing of intensive and sensitive data. For example, while downloading and streaming of files and content.
