# Is SRTP/TLS Voice encryption possible with sipgate trunking?

**No**, we do not offer any SRTP/TLS Voice Encryption with our sipgate trunking product.

With sipgate trunking calls are transmitted without any encryption. A possible **alternative** would be to **use encryption options provided via a VPN**.
