6.8.1 Key features
The key features of SIP encryption are:

SIP encryption can only be enabled for VoIP phones supporting TLS and SRTP.

By enabling SIP encryption, all SIP traffic (both signalling and media) between the VoIP phone and the Enreach Contact platform is encrypted.

SIP encryption can be enabled or disabled for each individual VoIP phone as long as the phone supports TLS/SRTP encryption.

Enabling or disabling SIP encryption will require a reboot of the VoIP phone.

Your network must allow that your VoIP phone can connect to the encrypted SIP proxy (securevoip.voipoperator.tel, port 5062).

TLS > TLSv1.0 or newer connections are accepted.

SRTP > AES-CM and AES-F8 ciphers are supported.
