In the world of voice over internet protocol, SIP Trunking is a technology that makes it possible for voice to be sent over the internet. It is used by many companies and private individuals for different purposes. For instance, it is being used for video conferencing. This method works well for conferences because the participants need not travel and are able to attend the conference at a later date. The conference attendees can simply connect to the conference call at their place of work or from their home via the Internet.
The SIP protocol was designed back in the 1990’s when the voice communication industry was in its infancy. It was created so that companies could make digital telephone calls over the internet using a simple system of digitally signed analog audio channels. This IP telephony system is used for voice as well as video calls.
A few decades ago companies had to buy long-distance phone lines in order to make local or toll-free telephone calls. These communications lines were expensive to operate and ran on costly supplies. There also had to be a huge switch station set up where all the wires converged. Most people did not have Internet access then and the long distance charges ate into the profits of the company. A switch station was also necessary because the company had to maintain several different systems.
VoIP simply means internet protocol over voice. When voice calls are made over IP lines, there is significant cost saving. The Internet itself offers far more bandwidth than the old phone networks. The bandwidth savings will depend on how many users are on the same network. The company has to rent the lines from different providers and divide the costs between them. The cost savings will obviously be quite a bit.
When talking about how does sip trunking work, it’s important to remember that there has to be a direct connection to the company’s phone system. This is done using a dedicated circuit network. Businesses typically have their own internal switches. These circuits are much less expensive than the ones used by individual offices and businesses.
An office that has private telephone lines can use its dedicated circuits to get telephone calls when the company has an Internet connection. When the Internet connection goes down, so does the connection to the dedicated circuit network. The office will have to get another telephone line going in order to make telephone calls. This is why some small companies don’t use their private telephone lines to make Internet calls – they have private lines and need to use an off-site connection.
SIP trunks are installed just like any other network device – inside the company’s network. There’s usually a router along with a set of interfaces – or IP networks – that are connected to the Internet. When a request comes from an outside world, the requests are handled by the outside world’s primary rate interface. It’s the primary rate interface that decide how much money the user will be charged for that call – and the IP network acts as the phone system.
To be able to take advantage of the benefits of sip trunking, small to medium sized businesses will need to find a provider that offers this type of service. The problem with finding a good provider that offers IP based voice is that there are so many companies that offer these services. Finding a low monthly rate for voice calls may not be as easy as finding a low rate for video conferencing. Video conferencing can be very expensive depending on where the video conference is being hosted – and how much time the participants spend talking on their cell phones. When a business needs to pay a low monthly rate for both voice and video conferencing, there may not be a good way to find a company that offers both services at the same price. However, small businesses that have just started using VoIP may find that they can easily meet these low monthly rates with an off site sip trunking provider.
