Configure TLS Proxy Pane
Note This feature is not supported for the Adaptive Security Appliance version 8.1.2.

Configuring a TLS Proxy lets you use the TLS Proxy to enable inspection of SSL encrypted VoIP
signaling, namely Skinny and SIP, interacting with Cisco Call Manager and enable the adaptive security
appliance for the Cisco Unified Communications features:
• TLS Proxy for the Cisco Unified Presence Server (CUPS), part of Presence Federation
• TLS Proxy for the Cisco Unified Mobility Advantage (CUMA) server, part of Mobile Advantage

certificate server.
• Local Dynamic Certificate Issuer—Lists the local certificate authority to issue client or server

• Client Proxy Certificate—Lists the proxy certificate for the TLS client. The adaptive security
appliance uses the client proxy certificate to authenticate the TLS client during the handshake
