SIP Trunk: what it is and how it works

IP technology has been developing for a long time, however, until the last decade, it has not become an essential tool in companies. For years, many companies have used VoIP for their internal communications – both in the same building, as between different, but all of their property – and only in part of their external communications, for which they continued to use conventional telephony.

 

Currently, more and more organizations are unifying their communications to use a comprehensive VOIP system, because the service providers began offering the so-called SIP Trunk, or SIP trunks.

 

While it is true that the evolution towards a one hundred percent IP system is slow, the trend is directed towards the adoption of this technology in an integral way and will continue in that direction for the next few years. This is due to the great advantages, not only economic but also operational and functional that VoIP technology offers companies.

 

What is SIP Trunk or the trunk

In order to use IP telephony in all communications and connections to the global telephone network through an Internet connection and thus emit or receive calls without having to use traditional telephony, with analog lines or through ISDN or primary links, We need an IP connection called SIP Trunk.

 

Through IP technology, voice is converted into data packets, in order to transmit that information over the network. In this process, the function of the Trunk SIP is to link the IP telephony service with the public telephone network.

 

For a company to benefit from this technology, which will provide multiple advantages, it must have an IP PBX, a good internet connection, an IP provider, an IP telephone or an IP adapter for analog phones and SIP clients that are the devices that will work as phones to receive or send calls.

 

Advantages of IP telephony

IP telephony is a breakthrough for companies, as it offers a number of possibilities that, with traditional telephony, would be unthinkable. These are some of the advantages of using a comprehensive IP telephony system for all company communications.

 

 

  • Reduce costs: the implementation of IP telephony in a company, according to experts, means a reduction in communications costs between 30 and 60 percent, depending on the type of company and its structure and organization.

 

IP providers offer their services in exchange for a monthly fee, which will vary depending on the number of numbers and the voice channels the company needs. However, this fee includes services such as voicemail or caller ID, among many others, which, through traditional telephony, represent an extra expense.

 

Another advantage, at an economic level, is that if a company hires IP telephony, the communication expense becomes fixed, which allows for greater forecasting and avoids unpleasant surprises.

 

  • Higher quality in voice calls: This technology allows you to offer great quality in voice calls. As telephony will use part of broadband to transmit calls, it is the IP provider who is responsible for prioritizing this data, compared to others, thus ensuring a maximum level of efficiency.

 

  • Integration with other applications: another of the important benefits of implementing IP technology is the ease of integration, especially if we use a cloud system. The possibility of integrating all the company’s management systems would be impossible, with traditional telephony and more complicated with a mixed system. However, with one hundred percent IP communication, it is a reality.

 

  • Remote maintenance: the IP provider is responsible for carrying out the necessary updates, as well as the maintenance actions that the system requires, monitoring its status at all times. In addition, the possible inconveniences that arise can be solved, to a large extent, remotely.

 

  • Scalability: the ease in implementing a VoIP system is such that it offers the possibility of making modifications quickly and without logistical inconveniences for the company when the needs of this vary.

 

  • Accessibility: finally, the possibility of accessing, from any device and anywhere in the world where there is an internet connection, offers the advantage that the company’s employees can carry out their tasks, without being physically in the offices, with the same security as if they did from there.
