VoIP security through decentralized blockchain

VoIP has been among the most anticipated technologies. It has been working to ensure telecommunication superiority. Keeping this in mind, service providers such as Contactivity work to offer good-quality services. Also, most service providers need top security to ensure their services remain smooth. Thus, blockchain in VoIP security has been an important aspect. The reason is that VoIP has been becoming a leading choice when it comes to business communication. VoIP offers hefty savings on operational costs, local call bills, and communication expenses. In this blog, we are going to discuss the advantages of VoIP and its use with blockchain. Moreover, we will discuss how service providers such as Contactivity are helping companies leverage the most out of current technology. Let us get started with our blog now.

Blockchain in VoIP: Enhancing Security and Privacy

Being a modern technology, VoIP has been powerless against security threats. The reason is that it has better potential than the older communication means. So, cybercriminals are looking for ways to disturb communication. They might have been successful to some extent. Yet, they cannot control the communication. Keeping this in mind, it is vital to have security practices in place to make VoIP security-proof. Blockchain applications for VoIP security can be a good option to choose from. It can fill all the loopholes that may affect the quality of service.

How can blockchain help?

Blockchain brings extra security to the existing system. It works by adding extra encryption to all processes, including communication and data transfer. It is always suggested that companies work to secure VoIP communication with blockchain. As discussed above, it can add a next-level authentication system. This helps, especially when you transfer video, images, voice data, and text over the network. The latest technology can help make sure that you have optimized call privacy. This may include masking numbers or substituting them. Another main feature of using blockchain is that it can use timestamp features. These features help users find specific transactions. Within a single click, companies can find out the transactions that need to be timestamped. VoIP security through a decentralized blockchain can offer these amazing advantages:

Data integrity:

Blockchain technology for encryption paves the way for the distributed ledger system. This means that your data transfer will be coated with next-level encryption. For instance, you wish to send a message to your customer. The blockchain will encrypt it. The message, once recorded, cannot be changed. The alteration can only be done if the subsequent block is altered. In a nutshell, it becomes tough for third parties to change or access the content. Moreover, it offers zero space for cyber hackers to tamper with the communication lines.


VoIP has been considered one of the most secure communication technologies. It is believed that they have been transforming communication methods. The primary benefit of having this technology is that it is secure. It offers the next level of encryption to make sure all messages are coded and cannot be altered. If you are enhancing VoIP privacy with blockchain, make sure the service provider provides you with advanced encryption algorithms. It can help you protect your data transmissions. This can help only those authorized recipients access and decrypt those messages.


It has been a vital aspect of secure systems to decentralize the infrastructure. By doing this, you are going to end all loopholes that might cause you problems. Most VoIP security solutions using blockchain perform this to reduce the risk of system downtime. It also stops the risk of network outages or possible security threats from cyber hackers. When you decentralize the network, you break it into individual nodes. Each node has a copy of the blockchain. Thus providing each node with vigilant resistance to attacks.

Identity Verification:

As mentioned above, blockchain has been considered among the modern security parameters. The blockchain in VoIP security can play an effective role in identity verification. This means that only authorized users can take part in VoIP communication. Thus, companies must get services from reliable service providers, such as Contactivity. The service provider has been enforcing modern identity verification protocols. It is to prevent impersonation and spoofing attacks.

Highest privacy and anonymity:

Most VoIP systems that are seen as successful have the highest level of privacy. For sensitive communication, it is vital to ensure anonymity. Among the recommended blockchain-driven VoIP security measures, anonymity during VoIP communication is preferred. As we are all aware of the transparency of blockchain, it is vital to install privacy protocols. In this regard, Contactivity can help you make anonymous calls while ensuring call encryption.

Smart contracts:

Blockchain-based authentication in VoIP works more on smart contracts. These contracts can help companies automate business. It can also help in enforcing rules. Companies can make certain agreements within the VoIP system. For example, they can make service-level agreements. They can also make payment processing rules or access control policies. VoIP has helped companies improve their security. It also enhances the image of the company.

Protection against DDoS attacks:

Decentralized trust in VoIP communication can make things easy for companies. It helps them by making systems resilient to these cyberattacks. Distributed Denial of Service may not completely affect systems with many nodes. In short, there is no single point that can be overwhelmed with malicious traffic.


As discussed above, blockchain has a decentralized nature. This helps with accountability and transparency. Thus, companies can verify the integrity of communication data.  Moreover, they can also authenticate users before they can make VoIP communication. Keeping this in view, Contactivity has one of the best CRMs that keeps companies on board about their agent performance and activity. Moreover, it offers them the added security benefit of agent authentication.

Contactivity and the blockchain:

Contactivity has been one of the first industry leaders to adopt blockchain. It has been implementing plans to ensure proper security for its clients. The blockchain in VoIP security has been part of its major security plans. The reason is that the ultimate goal of the company is to offer the highest level of call quality. Moreover, it has been working to ensure minimal system downtime and seamless connectivity. Alongside this, the service provider offers state-of-the-art features such as toll-free numbers, virtual local numbers, and call termination services.
