AES-CM encryption with a 128-bit key and HMAC-SHA1 message
authentication with a 32-bit tag.
Note: This parameter also affects the selection of the crypto in the
device's answer. For example, if the device receives an offer with two
crypto lines containing HMAC_SHA1_80 and HMAC_SHA_32, it uses
the HMAC_SHA_32 key in its SIP 200 OK response if the parameter
is set to 2.

43.4.4 TLS Parameters
The Transport Layer Security (TLS) parameters are described in the table below.
Table 43-23: TLS Parameters
Parameter Description
Web/EMS: TLS Version
[TLSVersion]
Determines the supported versions of SSL/TLS (Secure Socket
Layer/Transport Layer Security.
[0] SSL 2.0-3.0 and TLS 1.0 = (Default) SSL 2.0, SSL 3.0,
and TLS 1.0 are supported.
[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.
Web: TLS Client Re-Handshake
Interval
EMS: TLS Re Handshake Interval
[TLSReHandshakeInterval]
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).
