Chapter 14 Inspection for Voice and Video Protocols
History for Voice and Video Protocol Inspection
Improved SIP inspection performance on
multiple core ASA.
9.4(1) If you have multiple SIP signaling flows going through an
ASA with multiple cores, SIP inspection performance has
been improved. However, you will not see improved
performance if you are using a TLS, phone, or IME proxy.
We did not modify any commands.
SIP inspection support in ASA clustering 9.4(1) You can now configure SIP inspection on the ASA cluster.
A control flow can be created on any unit (due to load
balancing), but its child data flows must reside on the same
unit. TLS Proxy configuration is not supported.
We introduced the following command: show cluster
service-policy.
SIP inspection support for Phone Proxy and
UC-IME Proxy was removed.
9.4(1) You can no longer use Phone Proxy or UC-IME Proxy when
configuring SIP inspection. Use TLS Proxy to inspect
encrypted traffic.
We removed the following commands: phone-proxy,
uc-ime. We removed the phone-proxy and uc-ime
keywords from the inspect sip command.
