A Network Address Translation (NAT) aids with making internet searches and email easier. With a typical ISP, when you make an online connection, the computer that the ISP has connected to does not have its own IP address. Instead, your ISP assigns an external IP address to every device that connects to the ISP. This allows you only to know which data is being sent from which location. However, for two-way connections needed for SIP trunks, it can cause major problems.
The reason SIP is used is to provide internet access via a telephone system. But by itself, it does not provide the security and reliability. The internet connection needs to be properly secured. And if you don’t have it, your VoIP equipment cannot guarantee smooth communication. An internet connection without any security is like an open door for all kinds of malicious programs and spyware. For this reason, many VoIP service providers include some form of security as part of the package when you sign up for cheap sip trunking.
Security is especially an issue for VoIP users, because there is no firewall or other method of blocking internet connections. Therefore, you have to take extra precautions when you are using your cheap sip trunk system. That’s why some of the most reliable systems in the market today are those that provide integrated security and a robust firewall.
One of the best ways to improve your security when you are using a cheap sip trunking system is to use a trusted VoIP gateway. You can either opt to get the IP-based or the software-based solution. With an IP-based solution, you have the added advantage of blocking outgoing traffic based on the source IP address. However, this form of security does not work well when you are making outgoing calls through automated gateways. On the other hand, with the software-based system, you can choose to receive or block calls based on the IP address, the software, or even the identity of the user.
When you use cheap sip trunking technology, there is also another major problem related to security. This issue is called security holes, and these holes can be very convenient ways for attackers to exploit your system. To prevent this, you have to make sure that the software license associated with your system matches with the firewall settings on your computer. If you do not match the firewall settings properly, the hacker will be able to make calls through the computer. If you don’t want anyone else to be able to call you, then you will have to configure the firewall settings to block incoming traffic from certain IP addresses.
Another way to improve your security when you are using a cheap sip trunk provider is to make sure that you don’t provide any user name or password to your customers. The reason for this is simple: hackers can easily break into systems that have multiple users, as they can use the username and password to log into different accounts. As soon as you identify the type of security features that you are using in your cheap sip trunk, you should immediately disable them and move on to stronger ones. You should also take special care when selecting a SIP provider, as there are plenty of companies out there offering VoIP services at ridiculously low rates.
There is one feature however that you can always include in your cheap sip trunking service and that is auto detection of the best gateway servers that can take your calls. A cheap service provider usually has some problems with their call-processing servers, so it’s important that you identify and select the best one for your needs. The best auto-detection method for a VoIP service provider is known as a hop by hop. This method is perfect for enabling your cheap sip trunk service provider to discern the best gateway servers that can take your calls and enables you to decide whether to use the first one or go down to the next until you get to the right server.
Another major problem that most cheap sip trunk providers face is the issue of slow connection speeds. There are many factors that contribute to this problem and most of them are related to the quality of service provided. One of the main problems here is poor Internet connectivity, which is one of the biggest reasons why people use cell phones to make long distance calls. Even though you can use a cell phone to make a long distance call, the quality might not be good enough, and this is why most people prefer using land lines. The other problem that you might encounter is that the long distance charges might be high since most Internet service providers charge according to the distance that you have to call. So if you want to avoid making long distance calls at exorbitant costs, you should start looking for better Internet service providers, especially if you are from a remote area.
