Due to ongoing changes in the business communications market, an increasing number of companies are changing to SIP trunking services. A Webtorials survey revealed that one-third of surveyed businesses are now utilizing SIP trunking, and it?s saving them an average of 33 percent in reduced costs. SIP controls 89 percent of VoIP, 69 percent of unified communications and 65 percent of video conferencing media. One-in-three companies are currently deploying this infrastructure.
Lower expenditure is not the only advantage; SIP trunking also offers other benefits, such as the ability to make IP-to-IP calls when possible, and flexibility to add new lines. If growth in this sector continues, SIP-based unified communications could regain 23 percent of productivity that has previously been lost on inefficiently run communications infrastructure in large companies.
To encourage new businesses to jump on the SIP band wagon, and to help businesses that already have, Sonus is collaborating with publisher John Wiley & Sons to produce two "For Dummies" books, one covering the field of SIP-based unified communications and one on session management.
The reader-friendly SIP Trunking for Dummies will explain exactly how the infrastructure can reduce traditional telecommunication expenses by up to 75 percent. Session Management for Dummies will detail how an SIP-based infrastructure can be used to utilize a range of applications such as unified communications and video conferencing across different vendor systems.
?Most enterprises are familiar with VoIP and probably have begun at least thinking about implementing Unified Communications (UC) ? a suite of integrated voice, video, data, and text communications delivered via the VoIP protocol known as Session Initiation Protocol (SIP)," said the authors of the ?For Dummies? books.
They go on to explain that although many businesses are deploying SIP trunking, they are still connecting their PBXs (Private Branch Exchanges) using legacy Time Division Multiplexing (TDM) T1 lines. This increases the expense and complexity of the system and also means that the enterprise is not fully ready to take the next vital step in unified communications. A much more efficient way to connect PBXs is to bypass the expensive T1s and deploy an IP network that can utilize SIP trunking.
For companies that have multiple locations, SIP trunking can be particularly beneficial. Michael Finneran, principal at dBrn Associates, explains, ?You might have 10 SIMS in three different locations in three different time zones. But if you are not using a SIM in your Los Angeles office, it is available to make calls in your New York office." (CU) Link
