A SIP trunk is the use of SIP (Session Initiation Protocol) to set up communications over the Internet. Unlike in traditional telephony, where bundles of physical wires were once delivered from the service provider to a business, a SIP trunk is a connection from one point to another over the public Internet.

• SIP trunking reduces costs by eliminating the need for separate voice and data connections, and expands the potential for communications convergence using both voice and data together. As a company grows, all necessary infrastructures to handle additional voice/data traffic are already in place.
• Turn All Calls into Local Calls – This reduces long-distance charges, as SIP calls travel over the Internet to a termination point owned by a service provider.
• Get Rid of Costly 800 Numbers, but Not the Convenience – Instead of providing customers with an “800 number,” a SIP provides points of presence in multiple U.S. cities could establish local numbers in each city.
• Parallel your Cell Phone with your Desk phone – With SIP Trunking you will have the ability to receive calls to your cell phone and your desk phone simultaneously. You can answer your cell phone half way around the world and still transfer calls as though you were sitting at your desk.
• Direct Inward Dial Numbers – With DIDs through your SIP Service you can give each of your employees their own Direct line for as little as a dollar a month.

SIP trunking offers the benefits of converged communications and saves substantial expense by eliminating the need to purchase BRIs, PRIs or PSTN gateways. It also reduces expenses by terminating calls closer to the called party. When combined with a Panasonic Phone System you can take advantage of the many benefits of SIP with a system that pays for itself!
