SIP Trunking works by connecting your phone system to the internet via VoIP. Because of this, it also inherits some of the same security risks associated with using the internet. Your calls are potentially vulnerable because cybercriminals can intercept VoIP data packets. Fortunately, there are several SIP Trunk security practices that allow you to safely handle data.
Best Practices for Secure SIP Telephony
Encryption involves sending SIP data over a transport layer security (TLS) channel. This means that when you send data between a PBX and a VoIP Business Phone System it will transmit over a secure connection in encrypted IP packages. This is one of the best ways to protect sensitive data.
A firewall is a security layer between the internet and your devices. It continuously analyzes transmissions to and from your device and halts suspicious connections. Firewalls are based on numerous security rules to keep your data protected. They are a great SIP Trunk security practice to ensure that you keep unwanted connections at bay.
It sounds simple, but one of the most reliable ways to keep your information safe is through a tough password. Rather than using something easy to guess, you should make it long with special characters. This makes it challenging for a bot to guess.
Update Software Frequently
Your SIP Trunking software needs to be kept up to date. Make sure that you are regularly updating the software. Delaying updates leaves your system vulnerable to security threats.
A VLAN (or a virtual LAN) permits businesses to separate their communication lines. By employing a VLAN, your networks will be separated so that even if one is compromised, the others will not be affected.
