Oracle Sponsors Research Upon Building a Business Case for SIP Trunks

By Arvind Arora, TMCnet Contributor


Growing global business activities have been compelling companies to look for alternative ways instead of international calling. Now, arrays of digital calling solutions are ready to offer them the required help in these moments.

A new research upon Session Initiation Protocol (News - Alert) or ‘SIP’ trunking offers valuable insights as to how this technology can be adopted as a feasible solution by enterprises. Supported by Oracle (News - Alert), the study states that more often than not, companies switching to Voice or Internet Protocol or ‘VoIP’ implement SIP trunking during the third phase of their transition.


During the first phase, organizations make a shift to IP-Telephony by putting in IP-PBX (News - Alert) and IP phones. Earlier, this was done using H.323 or a proprietary protocol but SIP has evolved into the new industry standard of late. The second phase is using VoIP/SIP to interconnect auxiliary voice communication systems, such as voice messaging, call recording and IVRs.

While the research doesn’t aim to offer a business case for IP telephony, at the same time it takes the telecom prices in the continental United States into account and provides a comprehensive cost benefits analysis on SIP trunking.

Further, the study explains that the business case for SIP trunking is a six-step process and also offers the process and metrics for all of them as well. First step within the process is to comprehend the business requirements for voice connectivity, such as what will be the availability, capacity, quality and security features that the company will require within the service. After this, the enterprise needs to analyze present infrastructure and rates to work out the current voice communication costs. Later, the requests for proposals or ‘RFPs’ need to be initiated so that the costs for migration to SIP trunks can be calculated.

Within the next step, it is decided whether the centralized architectural model will be adopted by the company or the distributed one, after which the business case is integrated with a cost-benefit analysis. Finally, other vital reasons apart from money savings in implementing SIP trunking are also established.

The study also comprises of instructions on how to create a ‘SIP Trunking Calculator’ that can suggest how much savings the enterprises are going to achieve by making the transition to the technology. A number of appendices offer prices for WAN connections, SLA parameters, a model for private SIP trunks and sample international calling rates that further support in defining the SIP trunking business case for companies.

In April 2013, Oracle released its Oracle Communications Converged Application Server 5.1, a carrier-grade, standards-based development and deployment platform for next-generation communications services. The new communication service offers integrated support for Java, Web services and IP Multimedia Subsystem (News - Alert) or ‘IMS’ standards, enabling communications service providers or ‘CSPs’ to rapidly deploy voice, video and data services.
