As enterprises move on from legacy voice communications systems like the public-switched telephone network (PSTN), Session Initiation Protocol (SIP) trunking has emerged as a popular method of facilitating voice communications over the Internet. SIP trunking offers enterprises many advantages over legacy systems, including reduced costs, scalable architecture and enhanced reliability. But SIP trunking also creates new security challenges for enterprises, like SIP floods and toll fraud.
This essential guide covers the SIP trunking basics to ensure your enterprise is prepared to successfully deploy SIP trunks in your network. Read on for more of SIP trunking explained.
