How can you protect your SIP trunking from hackers?

2 Configure your firewall and router

Another important step to protect your SIP trunking from hackers is to configure your firewall and router properly. You should block any unauthorized or suspicious traffic from reaching your SIP server or endpoints. You should also use a SIP-aware firewall or a session border controller (SBC) that can inspect and filter SIP messages and prevent attacks such as denial-of-service (DoS), spoofing, or flooding. Moreover, you should update your firewall and router firmware regularly to patch any vulnerabilities.

3 Monitor and audit your SIP traffic

To protect your SIP trunking from hackers, you should also monitor and audit your SIP traffic regularly. You should use tools that can analyze and alert you of any abnormal or malicious activity on your network, such as unauthorized calls, high call volumes, or unusual destinations. You should also keep logs of your SIP traffic and review them periodically to identify any patterns or trends that indicate a breach or an attempt.

4 Educate and train your staff

One of the most common ways that hackers can compromise your SIP trunking is by exploiting human errors or weaknesses. Therefore, you should educate and train your staff on how to use your SIP trunking safely and securely. You should teach them how to recognize and avoid phishing, vishing, or social engineering attacks that can trick them into revealing sensitive information or granting access to your network. You should also enforce policies and procedures that regulate the use and management of your SIP trunking.
