This object creates and configures a profile for implementing the Transport Layer Security (TLS) protocol for use with SIP over TLS. TLS is an IETF protocol for securing communications across an untrusted network. Normally, SIP packets travel in plain text over TCP or UDP connections; Secure SIP is a security measure that uses TLS, the successor to the Secure Sockets Layer (SSL) protocol.
To add a TLS protection-level policy, you create a TLS PROFILE and configure each of the parameters. The TLS PROFILE named in a ZONE configuration object controls TLS behavior for all SIP Signaling Ports in the ZONE. An instance of a TLS profile called defaultTlsProfile is present by default, and is used by default by each ZONE; however, additional TLS profile instances may be created and used. The settings within the defaultTlsProfile may be modified. Also, the supported transport protocols must be set to allow SIP over TLS over TCP.

Parameter | Description |
|---|---|
| The name assigned to this Transport Layer Security (TLS) profile. Must be 1 - 23 characters. |
| Specifies the higher layer authentication timer in seconds. Must be 1-60 seconds. The default value is 5. |
| Specifies the time in which the TLS handshake must be completed. The timer starts when the TCP connection is established. Must be 1 - 60 seconds; default is 5. |
| Specifies the TLS session resumption period for which cached sessions are retained (in seconds). 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. Must be 0 - 86,400 seconds; default is 3600. |
Cipher Suite1 | Use this parameter to specify the first TLS Cipher Suite choice for this profile. |
