After the Sonus SBC 1000/2000 obtains the required certificates, configuration of several options/attributes on both the server and client is necessary before TLS can employ the certificate(s) in establishing a secure connection. The attributes are configured in TLS profiles. Attributes include, but are not limited to, such things as Client Ciphers, and inactivity timeouts.

TLS Profiles are used by SIP Signaling Groups when the TLS transport type is selected for incoming and outgoing SIP trunks (Listen Ports), and in SIP Server Tables when TLS is selected as the Server Host protocol.

Sonus SBC 1000/2000 supports TLS 1.0 and TLS 1.2. SSL 3.0 and SSL 2.0 are not supported due to security risks and vulnerabilities.

Working with TLS Profiles

  1. In the WebUI, click the Settings tab.
  2. In the left navigation pane, go to Security > TLS Profiles.
