Security on the internet is of paramount importance. As the internet has changed and grown over the years, so has the importance of encryption. There are many channels of data flowing all over, your business network, cell phone data networks, wi-fi hot spots, internet providers – home and business. Standard practice for service providers is to enable Transport Layer Security (TLS). TLS is why you get the green lock in the corner of your web browser.


If you browse to a website, and the lock is not visible, your communications with that server are not encrypted, and can be intercepted.

The same attention to security should also be applied to Voice Communications over the Internet (VOIP). The sad state of Voice Providers today is that most do not care about your security. 

There are 2 steps of encryption that must be run on a Voice Over IP network, to properly secure your communications. 

The first step is enabling TLS, as described above this provides security for your phone communicating with the phone system. This prevents people from intercepting who you are dialing, and your system credentials.

The second step is enabling SRTP. This feature is the actual encryption of your voice data stream. TLS encrypts the messages sent to the server, SRTP encrypts your voice. This means that even if someone was able to intercept your voice stream, it will be encrypted.

Enabling encryption becomes even more important when you are using an App on your mobile phone provided by your Voice Over IP Carrier. If your carrier does not use TLS + SRTP to secure your communications, when you are connected to public wi-fi, you are susceptible to multiple types of attacks.

Voipcom takes network security, and your privacy very seriously. We enable TLS + SRTP by default on every phone we support. If your voip provider does not provide this level of security, demand it, or even better switch providers to a carrier that takes your privacy seriously
