Understanding How Are SIP Trunks Delivered
When you think of how our SIP trunks delivered, you probably imagine the same way you would have if you had an online fax, or email service. You probably also imagine being able to get calls to your email address from anywhere in the world, as long as you had an Internet connection. SIP is short for any number of things, including SIP trunking service. The term “SIP” itself can mean either of these things. When you start looking at how our SIP trunks delivered, you will find that they are delivered as digital packets over the Internet, or through phone networks.
Essentially, these packets are sent over digital channels, just like an analog signal. Generally, these analog signals are replaced by digital ones, which are much faster, meaning they can carry more information, at higher bandwidth, and for longer distances. In order to understand how our SIP trunks delivered, it is important to understand how our SIP trunks work.
One of the most popular ways how are SIP trunks delivered is through using an IP telephony system, or IP Telephony. These IP telephony systems are used for voice over IP, or VoIP. Basically, this feature is used to connect two or more analog lines, through their IP connections, and allows one call to happen to many users at the same time. This is similar to how a fax works but instead of using ink and paper to transfer each page, it uses digital codes that are sent over the Internet, like an email. An IP telephone system can also be set up to allow multiple calls coming from different locations, with different amounts of bandwidth available, all from the same IP trunk.
Another way how are SIP trunks delivered is through a service provider. These service providers usually own or rent out large numbers of IP trunks, and they assign them to different users. Each user can then plug in their own phone number into the address of their choice, and have their call transferred to whichever phone they specify. Usually, there is a limit to the number of calls each user can make each month. Most Internet service providers charge extra for long distance calls, so you may want to check how are SIP trunks delivered through this type of service.
Another way how are SIP trunks delivered is through a voice over IP system, or a VoIP system. A VoIP system is a computer voice over internet service. It works much like your conventional telephone, with voice calls being placed directly to another phone, instead of being routed through the Internet. This is ideal for businesses that have employees who need to reach a conference call or have employees that travel frequently around the world. Because a VoIP system does not place long distance calls, it’s also perfect for people whose homes do not have cable internet.
One of the disadvantages of a VoIP system is that the quality of the sound does not quite match the sound quality of your regular analog telephone lines. Because the VoIP system cannot make as many long distance calls, or as many round trips, it can end up costing more money than it would to simply use an analog telephone line. However, the sound quality of a VoIP phone call is often as good or even better than that of an analog telephone call. This is another reason why many businesses prefer to use a VoIP phone system instead of an analog telephone line.
A third way how are SIP trunks delivered is through a private branch exchange (PBX). A private branch exchange is just like a telephone-network phone system, except it has different wiring between each office in the private branch exchange. Much like how a conventional public switched telephone network works with ten numbers in each block, each individual office in a private branch exchange will have its own telephone number. The benefit of a PBX is that each office in the private branch exchange will have its own IP address, which makes for a much more secure way of making telephone calls.
In order to learn how our SIP trunks delivered, it is necessary for a business to understand how the voice is transferred over the Internet. The way how the call is transferred is through the use of IP networks, and these IP networks are typically routed through the use of an IP network switch. A voice packet is then sent from one IP network to another, called an IP session. With this information, the different IP network switches at each office will then detect the packets, and then forward the information to the proper recipient. How are SIP trunks delivered using this method is by each office in the private branch exchange selecting an IP server that will be assigned to them, along with a port number. Once the server is set up at each location, each employee will connect to their server and use that port number to make phone calls back to their location.
