## VoIP Voice Traffic Encryption

**Are your calls secured? **If you have a [SIP-based VoIP phone system](https://www.univoip.com/blog/sip-vs-voip-whats-the-difference?hsLang=en-us) – chances are they are not.

You should contact your current provider and ask if they encrypt your Voice Communication AND Signaling Messaging.

**Fact #1** Most VoIP Phone Service Providers are deploying SIP based phones. SIP is a widely used standard with its content transported as readable text. Unfortunately this makes it an attractive target for hackers.

**Fact #2** Broadband service providers have been known to search for SIP messages (signaling messages) and RTP packet, containing the voice conversation, and restrict their use on their networks.

**Fact #3 **Most Internet based VoIP Service Providers are NOT encrypting the voice traffic nor signaling message, **making your conversation pretty much open to the public internet. **
