Should You Use SIP Trunking Encryption?

SIP Trunking EncryptionOne of the best technologies for telecommunications these days is SIP Trunking. SIP Trunking is used to replaced traditional telecommunication systems. It works through the internet to not only make and take calls but also to send data from one user to another. However, using the internet poses security risks. Fortunately, if you deploy SIP Trunking encryption it makes your communications more secure.

What is SIP Trunking?

In order to understand SIP Trunking encryption, you should first understand SIP Trunking itself. Session Initiation Protocol (SIP) Trunking provides online communication to users. It uses Voice over Internet Protocol (VoIP) to accomplish this. SIP Trunking is better than traditional communications in a few different ways. With SIP Trunking, you can experience cost savings and better scalability. SIP Trunking is also easier for companies to maintain.

SIP Trunking Security

One of the few drawbacks to SIP Trunking is the possibility of cyberattacks. For example, some hackers can employ DDoS attacks, buffer overflow attacks, or SQL attacks if you use the internet for your communications. Fortunately, SIP Trunking encryption can prevent this.

SIP Trunking Encryption

The good news is that most SIP providers encrypt their trunking services by default. However, this should be a two-sided process. The user needs to encrypt their end as well. Two SIP Trunking encryption protocols you need to employ are the Transport Layer Security (TLS) protocol and the Secure Real-Time Transport Protocol (SRTP). The Transport Layer Security protocol secures the data layer and the Secure Real-Time Transport Protocol secures the audio layer.

Additional ways of securing your SIP Trunking solution is by using Virtual Private Networks (VPNs) and IPSec tunnels. Both of these options add an extra layer of security for you.
