Most Internet subscribers will be familiar with the term SIP Trunking and will probably have heard of it from friends, relatives, colleagues and sometimes even online forums. But when it comes to SIP Trunking, what is it exactly? What are the different types of SIP Trunking?
SIP Trunking allows the use of one number (also known as an IP) within the Internet. This means that your email address, VoIP numbers and even a phone number can be used to make calls to other users who might not have the Internet connection at hand. It is important to note that this can only be done if both phones are in the same local network. In most cases, this will be possible for you provided that you share your VoIP service with at least two other people.
As an example, if you own a business that employs several hundred people, you would be best served by signing up for cheap SIP Trunk providers. These providers will enable your employees to make use of multiple numbers in one place.
The most common way that these cheap SIP Trunk Providers work is by allowing you to connect a number of phones to a single Internet connection, which is provided to all employees. This is typically done by using a telephone bridge, a set of devices that allow you to connect phones to the Internet and to a central phone server. A dedicated PBX is also needed so that you do not need to keep any phones at your disposal. Of course, this is not required and most providers do not require you to do so.
Another option is a hosted VoIP system that allows you to connect multiple phones to a single system. There are several providers out there that provide this service. However, you should be aware that these services are expensive. They are also very expensive to set up as the number of phone numbers that can be connected is limited.
The cheapest way to get cheap SIP Trunk Providers is to sign up for one-time use packages. This is especially good if you do not require much more than this, especially if you are still using an older VoIP phone system. To sign up for a package, all you need to do is find one that offers unlimited numbers for one year and pay it over a one monthly payment. Although this option is less expensive than having multiple numbers, it is not nearly as affordable as having the dedicated PBXs or using the same number for years on end. .
There are also other alternatives for cheap SIP Trunk Providers, such as tie-ups with different service providers. In this case, you can sign up for a number of different service providers and then share a central switch with them.
Once you have established yourself with cheap SIP Trunk providers, you can then add to your account as and when you need to and you can also use your cheap SIP Trunk providers as much as you want. However, be careful not to sign up for too many so that you end up paying too much for the same service.
Another way of saving money with SIP is by using a VoIP PBX. With a VoIP PBX, you can actually install your own VoIP phone, which you can use even when you have a landline. The phone that you will have to use will connect to the same SIP trunk as your regular phone line, which means you will not have to deal with any of the problems associated with connecting two different systems. Another advantage of having this type of phone is that you can still use your regular phones to dial local numbers as well.
As with other options, the problem with cheap SIP Trunk Providers is that you have limited the number of numbers that can be used for long distances, and therefore you might have to pay extra for long distance calling. Also, because the SIP trunk is not hosted, the service providers charge additional for installing and maintaining this kind of service.
It is best to go with a provider that offers both the VoIP PBX and the cheap SIP trunk as this will mean you save money both ways. One thing that you must bear in mind though is that you cannot choose between the two. If you want to get the cheapest rates, then it is best to get the cheapest provider available.
