    During the past few years, cloud communication systems have become increasingly popular in the business sector. Organizations around the globe are looking for different ways to add value to the business, using cloud backups, fiber internet connectivity, and phone service for businesses (cloud-based).

    According to the estimates of a 2016 survey, it was revealed that by 2017, 62 percent of the companies would be using SIP trunking. However, to understand how this technology can be successfully implemented, companies should utilize it to its full potential. Two of the commonly used terminologies in the cloud-based communication environment are IP Trunking and SIP Trunking.

    Many believe that these are two different names of the same technology, but it is not true. IP Trunking is used to deploy Voice over Internet Protocol (VoIP) at an enterprise level, using SIP Trunking or any other technology. Both SIP Trunking and IP trunking are VoIP technologies, but they are completely different.

    What is IP Trunking?

    IP trunking is the deployment of VoIP technology in a large-scale business environment. It can also be referred to as VoIP implementation if you incorporate unified communications (UC) feature in this technology.

    In IP Trunking, the voice is transmitted using data connectivity; which transmits electrical signals via it does not use analog phones to transmit data. It is not the same as other VoIP tools like Voyage or Skype. In fact, this technology is specifically designed to meet the reliability and security requirements of a company.

    Deployment of IP Trunking at an Enterprise Level

    There are a number of ways to deploy IP trunking at a company level. For example, businesses can either subscribe to the cloud-based communication services, or it can be deployed as an on-premises system, in which case, the enterprise will manage and own it.

    A business might also need SIP Trunks or PBX trunks for the successful deployment of IP trunking. SIP trunks are used to manage different types of multimedia, including instant messaging, emails, presence, video conferencing, voice, and more. On the other hand, the purpose of a PBX is to support the voice transmission.

    You can use this technology as an alternative to the PSTN (publicly switched telephone networks). It allows you to save cost, enable you to communicate even when you are traveling, reduce the overall risk by improving business communication, enable you to incorporate multimedia features to enhance functionality, and allow scalability. However, to ensure the quality of service with IP trunking, make sure you have sufficient data connectivity.

    What is SIP Trunking?

    Sip Trunking, on the other hand, are communication protocols that are used to manage multimedia transmissions. SIP stands for Session Initiation Protocol. The purpose of this technology is to support the key action that is required to receive or send calls. It can be used to transmit information, terminate the calls, and also to place a call. Telephony services with SIP trunking can either be hosted through a partnership with service providers, or it can be managed on premises.

    The alternative to SIP trunking is TDM (time division multiplexing) or PBX trunking. This technology is best for businesses that are planning to switch to UC tools. Companies can easily achieve IP trunking via PBX or media gateway, but it might also require SIP trunks and features such as call routing via SBC (session border controller).

    Benefits of SIP Trunking

    By using SIP trunking, businesses are able to use different media types. This technology offers support and flexibility in terms of using different multimedia. SIP trunking serves as an open standard, which makes it is easier to integrate it with other technologies.

    It allows you to get an immediate return on your investment. Businesses that shift to SIP technology without making capital expenditure usually tend to increase their cost savings. It enables businesses to grow faster across different locations by consolidating remote users and different locations. SIP trunking offers scalability and allows companies to expand rapidly with greater flexibility by opening new locations and setting up remote users.

    With the help of this technology, business employees can connect their mobile devices through user-friendly VoIP applications in a secure environment. This enables the frequent flow of communication and allows mobile workers to stay connected via the on-premises VoIP systems.

    All in all, IP trunking and SIP trunking are two different technologies with different uses and functionalities. Depending on the business requirements and the size of an organization, some prefer using SIP trunks, while others go for IP trunking.
