Carrier Evolution

Among enterprises, use of SIP trunking has provided an average 33 percent cost savings over legacy access methods, a study conducted by Webtorials, and sponsored by Sonus Networks, has found. For 73 percent of respondents, “saving money” was among the key drivers for adoption. But roughly half indicated that ability to use “SIP-specific” features also was an adoption driver.

SIP Trunking, by contrast, is still in the early stages of deployment. In fact, roughly two-thirds of the respondents reported either “Significant Use” or “Extensive Use” of VoIP, while only about one-third of the respondents reported either “Significant Use” or “Extensive Use” of SIP Trunks. Among those using SIP Trunks, significant cost savings have been realized, with an average savings on the order of 33%, Sonus Networks reports.

Some 68 percent of respondents indicated their decisions are driven “mostly by cost savings” or “about equally” by cost and capabilities.

VoIP (89 percent), Unified Communications (69 percent) and video conferencing (65 percent) are the most important types of media to be controlled using SIP.
