Use the TLS Profile to configure a profile for implementing the

TLS

protocol for

SIP over TLS.

The TLS profile is associated with a

SIP Signling Port.

Info
titleNote

The settings within the

...

default TLS Profile may be modified. Also, the supported transport protocols must be set to allow SIP over TLS.

1TLS Profile Parameters

Parameter

Length/Range

Description

tlsProfileName

1-23

Name assigned to this Transport Layer Security (TLS) profile.

acceptableCertValidationErrorsN/A

Use this parameter to specify if certificate chain validation errors are acceptable while validating the peer certificate.

  • invalidPurpose 
  • none (default) 

allowedRoles

N/A

Allowed TLS roles for this TLS profile.

  • clientandserver – (default) Choose to select both a TLS client and server role, depending on the request direction. This is primarily for peering applications.
  • server – The 
    Spacevars
    0product
    will only be a TLS server. This is primarily for access applications.

appAuthTimer

1-60

The higher layer authentication timer in seconds. (default = 5).

authClient

N/A

Indicates whether or not a TLS client is forced to authenticate itself within TLS. If set to false, the client is not required to authenticate itself at the TLS layer, but must complete authentication within a higher-level protocol after the TLS connection is established (that is, SIP registration).

  • false
  • true (default)

cipherSuite1

N/A

Use this parameter to specify the first TLS Cipher Suite choice for this profile.

See Supported Cipher Suites table below for the list of cipher suites.

cipherSuite2

N/A

Use this optional parameter to specify the second TLS Cipher Suite choice for this profile.

See Supported Cipher Suites table below for the list of cipher suites.

cipherSuite3

N/A

Use this optional parameter to specify the third TLS Cipher Suite choice for this profile.

See Supported Cipher Suites table below for the list of cipher suites.

clientCertName

1-23

The name of the default Client Certificate to be used by this TLS profile, created using the SECURITY PKI configuration object.

handshakeTimer

1-60

The time (in seconds) in which the TLS handshake must be completed. The timer starts when the TCP connection is established. (default = 5)

ocspProfileName1-23

Name of OCSP profile object referenced by TLS profile.

serverCertName

1-23

Specifies the name of the Server Certificate to be used by this TLS profile, created using the SECURITY PKI configuration object.

sessionResumpTimer

0-86400

The TLS session resumption period (in seconds) for which cached sessions are retained. TLS allows successive connections to be created within one TLS session (and the resumption of a session after a TLS connection is closed or after a server card failover) without repeating the entire authentication and other setup steps for each connection, except when the space must be reclaimed for a new session. (default = 3600)

suppressEmptyFragmentsN/A

Enable flag to prevent the SBC from inserting empty fragments when sending packets on TLS over TCP connection in support of older versions of TLS implementation.

  • disabled  (default)
  • enabled
v1_0N/A

TLS protocol version 1.0 (see note below)

  • disabled
  • enabled (default)
v1_1N/A

TLS protocol version 1.1 (see note below)

  • disabled  (default)
  • enabled
v1_2N/A

TLS protocol version 1.2 (see note below)

  • disabled (default)
  • enabled
