Voice over Internet Protocol, or VoIP, is a mature technology that first came into being in the 1990s. This technology, which allows the transmission of voice calls over the Internet, has grown rapidly since then. More than 20 years later, different companies, particularly those with multiple offices, are now using VoIP in so many ways.
Uses of SIP trunking
Many companies take advantage of the VoIP technology with SIP (Session Initiation Protocol) trunking. Businesses with regional branches or those with a campus of buildings mostly use this protocol. It allows some companies to have phone numbers in different countries without having their physical presence. If you have a hostel in Japan, for instance, and you want to have a phone number in Australia or the United States, with offices somewhere else, then a SIP trunk line can be a big help.
Great for remote staff
You can also use this to your advantage if you have remote staff. They can pick up the phone wherever they are, and answer customer queries, support or sales questions. Or you can have a local California phone number, and it gets routed to your line somewhere else. This is a virtual phone setup that routes calls to wherever you are in the world. The great thing about this is that the calls are technically free since they are already part of your Internet expenses. You only need to have the necessary SIP trunk infrastructure.
Reselling the technology
If you want, you can also resell SIP trunk services. SIPTRUNK, Inc. explains that the company provides the needed support, and all you need to do is sell to interested clients. If you use the technology, then you know that it works. There is no better salesman than someone who uses the product and enjoys its services himself. First-hand word of mouth is tough to beat.
