Sip Trunking

A SIP trunk is a direct connection between your organization and a Telephone service provider using the Internet. It enables you to extend your voice phone calls using an Internet Prorocol (VoIP) beyond your organization’s firewall to anywhere in the World. In addition to Voice phone calls, SIP trunks can also carry Instant Messages, multimedia Conferences, user presence information, Enhanced 9-1-1 (E9-1-1) emergency calls, and other real-time communications services.
