Chapter 42 Using the Cisco Unified Communication Wizard
Information the Cisco Unified Communication Wizard
• The wizard generates configuration settings for the Unified Communications proxies where
possible, automatically, without requiring you to enter data. For example, the wizard configures the
required access lists, IP address translation (NAT and PAT) statements, self-signed certificates, TLS
proxies, and application inspection.
• The wizard displays network diagrams to illustrate data collection.
To access the Unified Communication Wizard, choose one of the following paths in the main ASDM
application window:
• Wizards > Unified Communication Wizard.
• Configuration > Firewall > Unified Communications, and then click Unified Communication
Wizard.
Mobility Advantage Proxy: Secure connectivity between Cisco Mobility Advantage server and Cisco Unified
Mobile Communicator clients
Cisco Mobility Advantage solutions include the Cisco Unified Mobile Communicator (Cisco UMC), an
easy-to-use software application for mobile handsets that extends enterprise communications
applications and services to mobile phones and the Cisco Unified Mobility Advantage (Cisco UMA)
server. The Cisco Mobility Advantage solution streamlines the communication experience, enabling
single number reach and integration of mobile endpoints into the Unified Communications
infrastructure.
The security appliance acts as a proxy, terminating and reoriginating the TLS signaling between the
Cisco UMC and Cisco UMA. As part of the proxy security functionality, inspection is enabled for the
Cisco UMA Mobile Multiplexing Protocol (MMP), the protocol between Cisco UMC and Cisco UMA.
Presence Federation Proxy: Secure connectivity between Cisco Unified Presence servers and Cisco/Microsoft
Presence servers
Cisco Unified Presence solution collects information about the availability and status of users, such as
whether they are using communication devices, such as IP phones at particular times. It also collects
information regarding their communications capabilities, such as whether web collaboration or video
conferencing is enabled. Using user information captured by Cisco Unified Presence, applications such
as Cisco Unified Personal Communicator and Cisco UCM can improve productivity by helping users
connect with colleagues more efficiently through determining the most effective way for collaborative
communication.
Using the adaptive security appliance as a secure presence federation proxy, businesses can securely
connect their Cisco Unified Presence (Cisco UP) servers to other Cisco or Microsoft Presence servers,
enabling intra-enterprise communications. The security appliance terminates the TLS connectivity
between the servers, and can inspect and apply policies for the SIP communications between the servers.
Cisco Intercompany Media Engine Proxy: Secure connectivity between Cisco UCM servers in different enterprises
for IP Phone traffic
As more unified communications are deployed within enterprises, cases where business-to-business calls
utilize unified communications on both sides with the Public Switched Network (PSTN) in the middle
become increasingly common. All outside calls go over circuits to telephone providers and from there
are delivered to all external destinations.
The Cisco Intercompany Media Engine (UC-IME) gradually creates dynamic, encrypted VoIP
connections between businesses, so that a collection of enterprises that work together end up looking
like one giant business with secure VoIP interconnections between them.
There are three components to a Cisco Intercompany Media Engine deployment within an enterprise: a
Cisco Intercompany Media Engine server, a call agent (the Cisco Unified Communications Manager)
and an adaptive security appliance running the Cisco Intercompany Media Engine Proxy.
