What is SIP Trunking?SIP Trunking is an open industry multi-media signaling standard that allows voice equipment to interoperate with the enterprise voice equipment over an IP network. SIP Trunks enable enterprises to create a single, pure IP point-to-point network connection to the internet cloud. An enterprise SIP proxy peers with a carrier SIP proxy, with the appropriate federations and security protections between them. Through this logical network channel, SIP sets up and tears down voice calls, from where the call is routed via the IP backbone to its destination.
Why SIP make sense for your enterprise?SIP Trunking and networking means reduced monthly recurring cost of separate PSTN and data circuits to the premise. Costs associated with capital and operating expenses for dedicated PSTN interface hardware can also be eliminated. This means reduced hardware costs and eliminating the need for costly SIP gateways. These savings are especially greater for enterprises with multiple offices.
In addition to hard cost savings, SIP Trunking also delivers operational network efficiencies by improving communications between enterprises and their customers and business partners. The initial wave of VoIP benefits has been primarily limited to intra-enterprise communications. Communications between enterprises, even those that are VoIP enabled, still require a circuit-switched hand-off that impacts voice quality, adds complexity, and introduces unnecessary expense through intermediate carriers. With SIP Trunking, it addresses network bottleneck, costs, and flexibility issues. SIP Trunks allow the enterprise to take advantage of SIP termination and origination services that effectively transition PSTN connectivity for long distance and local access calls. The enterprise only requires a single point-to-point connection to Networld's cloud. Communications between enterprises still require circuit-switched hand-off but it is now being handled by the IP backbone to the closest PSTN gateway, where the call is converted to TDM for the last mile.
For enterprises with multiple locations, calls from one location can be re-directed to another location without interference to customers and business partners. Features and Benefits of a Quality SIP Provider
