Tips on Securing Your VoIP System

Many businesses use email and instant messaging to communicate with each other. Voice systems allow you to connect with anyone, anytime, and anywhere. VoIP has been popular in the previous years due to its economical pricing among big or small businesses. It opened new streams of opportunities with its advanced features aside from being able to choose a payment plan that suits your business.  

As businesses adopt VoIP as a lucrative communication solution, will it introduce new security risks in the organization? The answer is yes. VoIP is internet-based. The network environment of VoIP is susceptible to attacks that extend beyond spamming and eavesdropping.   

Cybercriminals may use VoIP as an entry point to your business network. That’s why security protection is a must for every cloud-based service that's plugged into your business.  

Fool-proofing your VoIP  

Protecting your voice network is much like protecting a data network. Organizations need to be meticulous in overseeing IT management and security requirements.  

Take the following tips to ensure seamless collaboration on your VoIP system. 


1. Have your network infrastructure evaluated   

Ensure your network infrastructure is safe and secure through an evaluation. Getting it evaluated makes sure that your network switch is brought up to date to accommodate and optimize voice signals. Voice signals now travel the same lines as data. It is important that all should be assessed to continuously experience high-level quality calls and voice functionality. 


2. Apply a physical and logical protection   

Having control over your administration is crucial for protection. Setting up a firewall and an intrusion prevention system (IPS) help monitor and filter authorized and unauthorized VoIP traffic, and track unusual voice activities. This allows you to control incoming and outgoing traffic on the VoIP network the same way as they do for other web-based traffic—giving your VoIP a firm foundation for security.  


3. Encrypt sensitive voice traffic by using VPN    

VoIP calls are transmitted over the Internet unencrypted, which allows malicious hackers to intercept data packets and record calls. A virtual private network (VPN) helps enhance VoIP security by encrypting voice traffic and mitigating the threat of an attacker using a network analyzer to capture the data.  


4. Apply strong passwords

Leaving the default admin password or using a weak password makes your VoIP at risk. Default VoIP passwords are publicly available. Immediately changing the default password to a strong password adds another layer of protection. The key aspects of a strong password are length (the longer the better), a combination of letters (upper and lower case), numbers, symbols, no ties to personal information, and no dictionary word.  


5. Implement strict security policies with users

Begin by creating and implementing a policy about your voice solution across your organization. One of the best ways to protect your organization from cybercriminals is to ensure that your end-users are educated about potential risks. Communicating your VoIP’s security features give your end-user a working knowledge on how to prevent or respond to the situation.  

Given the rise in cyberattacks, bandits are still on the run exploiting VoIP vulnerabilities and weaknesses.
