Webtorials has released its annual State of the Market Report, titled “2015 Unified Communications, SIP, and SBC Plans and Priorities.” The report observes a significant shift in recent years from UC solutions based on a single-vendor to standards-based, multi-vendor solutions—with Session Initiation Protocol (SIP) as the “key enabling technology” adoption for the shift apparent in both enterprise and Service Provider networks.
SIP usage has also grown significantly because service providers are offering better SIP prices and bundles, delivering SIP trunks as a replacement for traditional T1, PRI and analog trunks; SIP support for multiple interactive media has also been a factor.
Among the other key findings:
- Of those who responded to the survey, 72% had either partially or fully deployed UC solutions, and most of the rest were or would soon be in the planning phase.
- Most UC and enterprise voice deployments are premises-based, though that is expected to drop as future deployments move more to the cloud. Hybrid deployments are the preferred approach to UC in the future.
- Respondents indicated a desire to move from proprietary to standards-based solutions, although the movement toward that goal is not happening rapidly.
- A dramatic increase in the use or planned use of SIP for various functions over previous surveys. The largest increase was for “Web conferencing” at 131%, and the overall average increase for all functions queried was 80%. The smallest increase was 21% for “Enterprise voice” because it already had a 59% usage that increased to 71%.
- As an integral part of UC capabilities with SIP trunking, the functions of session border controllers (SBCs) are becoming much more recognized. The primary reasons cited for SBC deployment involve security, with ensuring a high quality of service also showing great importance.
