SIP Trunking deployment was up 50% in 2013 compared to 2012, primarily driven by activity in North America.*
Increasingly, companies are utilizing Session Initiation Protocol (SIP) trunks to extend the benefits of IP into their connections with the Public Switched Telephone Network (PSTN). SIP trunks offer the potential for cost savings on telephone service charges and legacy equipment upgrades, flexibility in scaling call capacity, enhanced business continuity capabilities, unified communications, as well as a future-proof network solution plan.
