TLS Parameters

The Transport Layer Security (TLS) parameters are described in the table below.
Parameter
Web/EMS: TLS Version
[TLSVersion]
Web: TLS Client Re-Handshake
Interval
EMS: TLS Re Handshake Interval
[TLSReHandshakeInterval]
Version 5.8
Defines the offered SRTP crypto suites.

[0] All = All available crypto suites (default)

[1] AES_CM_128_HMAC_SHA1_80 = device uses AES-CM
encryption with a 128-bit key and HMAC-SHA1 message
authentication with a 80-bit tag.

[2] AES_CM_128_HMAC_SHA1_32 = device uses AES-CM
encryption with a 128-bit key and HMAC-SHA1 message
authentication with a 32-bit tag.
On a secured RTP session, this parameter determines whether to
enable Authentication on transmitted RTP packets.

[0] Enable (default)

[1] Disable
On a secured RTP session, this parameter determines whether to
enable Encryption on transmitted RTP packets.

[0] Enable (default)

[1] Disable
On a secured RTP session, this parameter determines whether to
enable Encryption on transmitted RTCP packets.

[0] Enable (default)

[1] Disable

Table 6-23: TLS Parameters

Defines the supported versions of SSL/TLS (Secure Socket
Layer/Transport Layer Security.

[0] SSL 2.0-3.0 and TLS 1.0 = SSL 2.0, SSL 3.0, and TLS
1.0 are supported (default).

[1] TLS 1.0 Only = only TLS 1.0 is used.
When set to 0, SSL/TLS handshakes always start with SSL 2.0
and switch to TLS 1.0 if both peers support it. When set to 1,
TLS 1.0 is the only version supported; clients attempting to
contact the device using SSL 2.0 are rejected.
Note: For this parameter to take effect, a device reset is
required.
Defines the time interval (in minutes) between TLS Re-
Handshakes initiated by the device.
The interval range is 0 to 1,500 minutes. The default is 0 (i.e.,
no TLS Re-Handshake).
