Take advantage of our secure network and the flexibility to customize your services


What is a SIP trunking phone system?

SIP trunking is an internet-powered voice solution for businesses that own their IP PBX system. You may have heard of VoIP (voice over internet protocol), a broad term for phone services over the internet. In addition to voice calls, SIP (session initiated protocol) trunks allow for transmission of a wider variety of media, such as text and video.
