Adding a TLS Proxy Instance
Note This feature is not supported for the Adaptive Security Appliance version 8.1.2.
Use the Add TLS Proxy Instance Wizard to add a TLS Proxy to enable inspection of SSL encrypted VoIP
signaling, namely Skinny and SIP, interacting with Cisco Call Manager and to support the Cisco Unified
Communications features on the ASA.
This wizard is available from the Configuration > Firewall > Unified Communications > TLS Proxy
pane.
Step 1 Open the Configuration > Firewall > Unified Communications > TLS Proxy pane.
Step 2 To add a new TLS Proxy Instance, click Add.
The Add TLS Proxy Instance Wizard opens.
Step 3 In the TLS Proxy Name field, type the TLS Proxy name.
Step 4 Click Next.

(CUMA) server. See Add TLS Proxy Instance Wizard – Server Configuration, page 18-9.
After configuring the server proxy parameters, the wizard guides you through configuring client proxy
parameters (see Add TLS Proxy Instance Wizard – Client Configuration, page 18-10) and provides
instructions on the steps to complete outside the ASDM to make the TLS Proxy fully functional (see Add
TLS Proxy Instance Wizard – Other Steps, page 18-12).
