Frequently Asked Questions

What is SIP trunking and how does it differ from traditional phone lines?

SIP trunking replaces traditional analog or PRI phone lines with internet-based voice connectivity, allowing your business to make and receive calls over your existing data network. Unlike legacy systems that require physical copper lines and costly hardware, SIP trunks deliver voice traffic digitally—offering instant scalability, geographic number flexibility, disaster recovery failover, and lower per-line costs. Most businesses experience 40-60% monthly savings compared to traditional telecom contracts while gaining enterprise features like call routing, number portability, and multi-location support.
