SIP Trunking
SIP trunking enables businesses to converge voice and data on a single network. It is available to customers who have SIP-capable IP PBXs. The SIP trunking service will deliver multiple simultaneous calls over an Ethernet circuit instead of traditional ISDN circuits. Instead of using physical trunks with copper wires, SIP trunking establishes virtual IP channels for real-time communications over an Ethernet connection, be it voice, data, video, or messaging. SIP trunking is essentially the IP version of a PRI (Primary Rate Interface) trunk. It provides customers with access to and from the PSTN for voice calls. The SIP trunk is provisioned between the customer’s IP PBX and the Hargray Network. SIP trunking will support direct inward dialing (DID) and a limited set of call features such as caller name and number. Customers who purchase SIP trunks will have IP PBXs that will serve as the primary source for many features.
