SIP Technology - What are the benefits?

The Session Initiation Protocol (SIP) is a signaling protocol that is transforming the telecommunications industry. Some signaling protocols as well as peer-to-peer technology already exist; however, SIP is fast becoming the standard in this field.

SIP is a stable protocol, extremely efficient, flexible and secure. Vendors meet on a regular basis to test their products together to insure interoperability. These meetings are called SIPit for SIP Interoperability Tests. If you are looking for a way to have applications interoperate with other tools, equipment, and servers; SIP is a sensible choice.

SIP Based Trunks

SIP Trunking is a new product in the VOIP industry that offers many benefits to small and medium businesses. It can reduce or even eliminate the costs associated with the purchase of hardware media gateways. SIP Trunks are provided over the same circuit used for data/internet reducing costs of carrier services. It reduces toll charges from SIP origination/termination services to the PSTN for external long distance and local access calls. SIP utilizes bandwidth more efficiently and supports multiple forms of communication (including video and instant messaging).

Similar to ISDN.PRI dedicated service, SIP offers DID's (Direct Inward Dialing) that allows every extension on your system a unique phone number. This allows better call control and simplified dial plans. SIP Trunking is an improvement over legacy VOIP solutions because each trunk is a dedicated channel. Finally, SIP simplifies adding, subtracting and changing lines.
