According to numbers from The Eastern Management Group, the SIP trunk communication industry is growing by 5 million supported devices per year. Additionally, the industry will only grow in the coming years, as an Infonetics Research report stated 58 percent of American businesses said they will use SIP trunks in 2015. This is a large increase from today's numbers, which stated 38 percent use SIP trunks.
Cost and a decreased bottom line are two of the biggest factors in the growth of SIP trunk adoption. Techday stated businesses could cut their communication costs in half by utilizing SIP trunking technology for their voice calls.
Furthermore, many VoIP plans supported by SIP trunks have a variety of cost options, including unlimited calling and other features. Some systems also allow use of multiple SIP trunk providers, enabling the caller to use "least-cost-routing" to select the most cost efficient provider for the location being called, according to Techday.
A true testament to the cost saving abilities of using SIP trunks is the case of Finish Line, a national retailer of sports footwear and apparel with 700 locations. Derrick Mitchell, Finish Line enterprise voice supervisor, stated in Network World that the company saved $2 million in communication costs over three years using SIP trunk supported calling.
Hosted and Open Source Telecommunication
Hosted PBX sales are also increasing, further driving increased adoption of SIP trunks, stated No Jitter. Although hosted IP-PBX systems have a smaller installed customer base compared to other unified communication technologies, the market is significantly growing. While hosted PBX comprises less than 10 percent of all PBX sales, the percentage of shipments has more than doubled in the last few years, with 3.6 percent in 2010 increasing to 8.7 percent in 2012.
Open source telecommunication software, like Asterisk, also makes up a large portion of the SIP phone market, according to No Jitter. The average size of open source PBX systems has increased by 60 percent, from 34 endpoints in the total open source market to 54 endpoints in open source PBX appliances.
Sangoma's analog, digital and BRI gateway products support a wide range of line codes and protocols, allowing enterprises of all sizes and with all types of telephony equipment to improve
