Over a while, Session Initiation Protocol (SIP) trunking has gained a lot of attention. However, few people are still confused about the usage of SIP trunking as they think that it could lead to phone fraud and corporate spying. Despite all these concerns, the implementation of SIP trunking technologies is growing day by day. The global Session Initiation Protocol trunking market was valued at US$ 13.44 billion in 2019 and is expected to reach US$ 30.22 billion by 2027. The market is likely to grow at a CAGR of 10.8% from 2020 to 2027.
What do you know about SIP and how it works?
SIP or Session Initiation Protocol is an effective way to make and end connections for data and voice transfers over the internet. It is an application layer protocol used to set up real-time sessions of audio/video between two endpoints. Modern trunking is all about a virtual link between the PBX and the standard phone network (the PSTN) with the help of an internet connection. In all, SIP technology makes it easier to create, modify, and terminate sessions with one or more parties in an IP network. It can either be a two-way call or a multi-party conference call.
Now let’s come to how Session Initiation Protocol trunking works? As mentioned above, SIP trunking is a virtual link between the PBX and the PSTN. It is a virtual version of an analog phone line. A SIP service provider can use SIP trunks to connect one or many channels to its user’s PBX system. Thereby, allows them to make local, long-distance, as well as international calls over the internet. SIP trunking provides users access to PSTN over an internet broadband connection. It also allows several connections from one single line via the internet connection. Thus, help businesses to save huge on their communication system. They can also scale their system as per their business requirements.
When it comes to setting up the SIP trunking, many users worry about their data security and any vulnerabilities or loopholes in the security. It is important to set up the SIP trunking safely to get the most out of it to prevent such concerns. Here are some of the key steps that suggest how to set up SIP trunking safely. Have a look:
Key steps to setting up SIP trunking safely
- Make sure to keep up with updates for firmware and software: This is one of the most important steps in setting up the SIP trunking to ensure its safety. Cybercriminals can easily take advantage of cloud-based software if they are not updated or have some loopholes. Keeping up with the updates for firmware and software allows businesses access to the most advanced security features. These features can help to prevent any kind of glitches that may lead to a security threat.
- Allow only secure connections: In today’s time, many organizations are working on policies like remote or mobile workforce, Bring Your Own Devices (BYOD) policies, etc. Any unsecured connection may lead to vulnerabilities. Any loopholes in internal networks open the doors for hackers to enter into an organization’s network. This way, they can easily target confidential corporate data and communication accounts. Since SIP connections work on the internet, any internet security challenges may let hackers target data packets, resulting in the loss of information. Besides, the organizations are vulnerable to snooping or spying practices used by other organizations, especially intelligence agencies. So, how do you deal with all these situations? The only way to tackle such security threats is by investing in highly secure connection protocols. Nowadays, several options are available such as secure socket layers for remote employees, virtual private networks, etc. It is also important to avoid using public or unsecured wifi networks. Other security measures that organizations can implement to secure their system include anti-virus, firewalls, anti-spyware, etc. For added security, organizations can make use of Socks proxies. It helps organizations navigate the digital space without worrying about hackers tracking their location via their IP address. This proxy also helps to encrypt data, thus providing tight security for the information.
- Choose the right SIP provider: It is important to choose a SIP provider carefully. Choose the one with strong existence and a good reputation in the marketplace. The service provider must provide all the security measures that ensure that only trusted connections can enter into an organization’s network. Organizations must also add the providers to the IP whitelist so that they can block any unauthorized accounts.
- Be careful while choosing the passwords: There is no doubt that advanced technologies have made our lives much easier. However, there are few people like cybercriminals who utilize the benefits of these technologies to harm others. They can use advanced techniques to hack an organization’s network to access their crucial data. It takes minutes for the hackers to crack the passwords. Therefore, it is important to set the passwords very carefully. Always choose a password that combines letters, numbers as well as symbols. Also, never use the same password for all the accounts. Choose a unique one for all the accounts so that if by chance one account gets hacked, the hacker will not be able to access the others with the same password. One more important thing to note is that organizations must never stick to the same password. They must change their passwords frequently for security purposes.
- Get the source code from genuine repositories: These days, several source code repositories are available online to choose from. These repositories serve the unique business requirements of organizations based on the type of projects like multi-developer projects, open-source projects, and more. When it comes to choosing a source code repository, organizations must go for a trusted source. For instance, if we talk about PBX installations, organizations must download PBX installation files from the manufacturer’s website or some trusted source that ensures complete data security.
So, these are some of the most effective ways or steps that organizations must follow to ensure the security of their SIP trunking.
