Finding: Businesses Embracing SIP Trunking in Big Numbers

The communications cost for businesses is no small matter, and it gets more expensive as the company grows. Developments in information and communications technologies (ICT) have introduced cost-effective options with features that were previously only available to enterprises. Session Initiation Protocol (SIP) trunking is one such development, and more businesses are deploying the technology to access the benefits it offers.

In an article by Pejman Roshan (News - Alert) on, he explains why more businesses are turning to SIP trunking. He cites the recent 2015 SIP Trunking report by review website Software Advice on how information technology decision-makers select SIP providers. The report revealed the adoption and growth rate of the technology have surpassed expectations, while at the same time delivering high levels of satisfaction among users.

According to Roshan, “SIP Trunking’s accelerated growth is a sign of its effectiveness. Users continue to learn its value and benefits, and more and more IT departments are making the transition, which makes VoIP and landline/cellular calls easier to connect.”

SIP trunking makes it possible for organizations looking to expand the capability of their communications solution without a large capital expenditure or on-premises infrastructure. With the right SIP trunk from an ISP, businesses can get global connectivity over the Internet with many of the features that are essential in today’s digital communications ecosystem.

The Software Advice report revealed 69 percent of IT decision-makers in the survey have already adopted SIP trunking in their organization, and 73 percent said they are “very” or “extremely satisfied” with the audio quality of calls connected by their SIP providers.

One of the benefits of SIP trunking is the ability to consolidate services, and fifty-three percent have fully consolidated their phone systems, broadband Internet connections and SIP trunks into a single provider. However, there is still some concern in deploying the technology as decision makers said security, quality support and pricing models are issues in choosing SIP providers.

Considering the current digital threat landscape, it is no wonder companies are concerned about finding the SIP provider that will deliver the most robust security protocols. Close to one in four of the respondents said they chose their provider on the basis of its security capabilities.

If you are looking for a company with a strong security system in place, one of the capabilities you should look for is secure real-time transport protocol (SRTP), a codec that allows for the encryption of audio streams. A more widely available protocol is transport-layer security (TLS), which can also be used to encrypt the actual SIP messages that control communications sessions instead of the content, such as the voice or video call.

As with any technology an organization chooses to deploy, it must be selected based on what it can deliver for their particular needs. While SIP trunking may be the ideal solution for many organizations, it may not be for some.
