Cisco ASA Series CLI Configuration Guide
Chapter 1 Configuring the TLS Proxy for Encrypted Voice Inspection
Prerequisites for the TLS Proxy for Encrypted Voice Inspection
shows the default and maximum TLS session details by platform.
Prerequisites for the TLS Proxy for Encrypted Voice
Inspection
Before configuring TLS proxy, the following prerequisites are required:
•
You must set clock on the security appliance before configuring TLS proxy. To set the clock
manually and display clock, use the
clock set
and
show clock
commands. We recommend that the
security appliance use the same NTP server as the Cisco Unified CallManager cluster. TLS
handshake may fail due to certificate validation failure if clock is out of sync between the security
appliance and the Cisco Unified CallManager server.
•
3DES-AES license is needed to interoperate with the Cisco Unified CallManager. AES is the default
cipher used by the Cisco Unified CallManager and Cisco IP Phone.
•
Import the following certificates which are stored on the Cisco UCM. These certificates are required
by the ASA for the phone proxy.
–
Cisco_Manufacturing_CA
–
CAP-RTP-001
–
CAP-RTP-002
–
CAPF certificate (Optional)
If LSC provisioning is required or you have LSC enabled IP phones, you must import the CAPF
certificate from the Cisco UCM. If the Cisco UCM has more than one CAPF certificate, you
must import all of them to the ASA.
Chapter 1, “Configuring the Cisco Phone Proxy.”
For example, the CA Manufacturer certificate
is required by the phone proxy to validate the IP phone certificate.
Configuring the TLS Proxy for Encrypted Voice Inspection

With the 10,000-session UC license, the total combined sessions can be 10,000, but the maximum number of Phone Proxy sessions is 5000.
