What are SIP Trunking and How Does it Work?
What is SIP trunking and how does it work? SIP trunking is an innovative communications technology for both home and business telephone systems. Unlike traditional unsecured landlines, which link the starting point to the end point through a series of complex PBX lines, SIP trunking is performed over your existing WiFi. You are able to talk to anyone, anywhere, using any broadband Internet connection at any time. This includes any device with a Web camera and/or microphone.
In this day and age, there is no reason why business communications cannot take place between mobile devices. Businesses can branch out with small office networks in different locations and still maintain unified communication with branch offices across the globe. This is much more cost effective than building out traditional long-distance or virtual branch networks. This is also much more efficient when it comes to using existing wiring. And, of course, this is all possible thanks to SIP trunks.
In essence, SIP trunking allows companies to provide their employees access to local, toll-free numbers as well as conference calls through their company’s Internet connection. Without this service, companies would have to buy their own cell phones and IP telephones to accommodate their employees’ call forwarding needs. These telephones and IP phones from third parties cost money. Plus, these systems rarely integrate with business communications infrastructure, such as cell phones and office networks. SIP trunks bridge the gap and enable business communications to be completed within the organization itself without outside connections.
SIP trunks are the voice over internet protocol that allows voice calls to be placed on Internet lines instead of using public phone systems or private connections like a router. This allows for much greater capacity and reliability than regular phone system. When VoIP telephone systems and IP telephones are implemented properly, they can dramatically improve the productivity of an organization’s workforce. In fact, some studies have shown that the increased productivity has been seen in just one year alone!
Most people familiar with how SIP works are already familiar with how SIP trunks work. But if not, SIP trunks make implementing phone system integration much easier. Basically, an IP phone server is first installed within a site that uses standard phone systems and IP phones. From there, employees can log in and use their current telephone numbers to dial into the Internet service provided by the company’s Internet backbone.
The beauty of this technology lies in its simple application. Almost every business with an online presence can take advantage of what is known as SIP trunking. For instance, if a website owner wants to create an instant messaging (IM) application that connects with a back office system via Internet, all he has to do is find a service provider that offers the technology and sign up for a monthly service plan. Within minutes, messages can be sent and received, and a user would only need to pay for what he uses.
SIP trunks are also used with websites and web based applications. For instance, companies may choose to place their own Internet phone system within their own data centers. This would allow them to offer free or low cost VOIP applications and voice communication over the Internet. Companies that use SIP trunks will also be able to make use of Internet based emailing and conferencing applications. All these can be done without having to set up a separate system for each application, which makes things a lot simpler and reduces costs.
As you can see, what is SIP trunking and how does it work is becoming increasingly important in both voice and data communications. It is also useful for companies that want to have a single data and voice communications system integrated with their Internet network. This would allow them to provide free or low cost Internet access and Internet phone service directly to their customers. The advantages of this are many. One such advantage is the reduction of costs to customers who no longer need to buy additional hardware such as phone lines or headsets.
