What services can be enabled with Cisco Expressway-c?
Mobile and remote access, as well as business-to-business services, can be enabled as part of the same Cisco Expressway-C and Expressway-E solution pair. Interworking — The capability to interconnect H.323-to-SIP calls for voice, video, and content sharing.
Why does Expressway-c require a traversal zone for business to business calls?
Since Expressway-C is deployed in the internal network and Expressway-E is in the DMZ, Expressway-C has to be connected to Expressway-E through a traversal zone for business-to-business calls. Mobile and remote access requires a separate traversal zone, referred to as Unified Communication traversal zone.
What is the difference between Expressway-c and Expressway E interface?
The Expressway-E external interface can be statically translated by NAT, but the Expressway-E internal interface can be statically translated by NAT only if the Expressway is not clustered. The Expressway-C interface can be translated by NAT.
Is a connection from the Internet to expressway C encrypted?
A connection from the Internet for business-to-business communications between Expressway-C and back-end application services may or may not be encrypted, based on the configuration and dictated by the corporate policies.

What is the difference between Cisco Expressway-C and E?
Differences between VCS C and VCS E Tandberg's legacy devices typically used VCS Control, or VCS C, within the organization and VCS Expressway, or VCS E, was used between firewalls. To put it more simply, VCS C was used internally within the organization while VCS E was utilized externally.
Is Expressway secure?
Secure communication is possible with Expressway because it uses two servers. The core server, known as Expressway-C, sits inside and acts as a firewall traversal client. The second server, Expressway-E server, is on the edge of your network and is the only point of access to the public Internet.
What are MRA phones?
Basically, MRA (Cisco Unified Communications Mobile and Remote Access) allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging and presence services provided by CUCM when the endpoint is outside the enterprise network.
How do you set up an MRA?

What is VCS Expressway?
The VCS Expressway is a SIP Registrar & Proxy and H. 323 Gatekeeper for devices which are located outside the internal network (for example, home users and mobile worker registering across the internet and 3rd party businesses making calls to, or receiving calls from this network).
What is Expressway-C and expressway-E?
In the example deployment two DNS servers are configured for each Expressway, which provides a level of DNS server redundancy. The Expressway-C is configured with DNS servers which are located on the internal network. The Expressway-E is configured with DNS servers which are publicly routable.
What is off-premises access?
Off-premises access: a consistent experience outside the network for Jabber and EX/MX/SX Series clients
Can a third party SIP device register to Expressway C?
Third-party SIP or H.323 devices can register to the Expressway-C and, if necessary, interoperate with Unified CM -registered devices over a SIP trunk.
Does MRA require Expressway?
Any MRA solution requires Expressway and Unified CM, with MRA-compatible soft clients and/or fixed endpoints. The solution can optionally include the IM and Presence Service and Unity Connection. This guide assumes that the following items are already set up:
How does the Expressway work?
The Expressway can limit the number of times that any user's credentials can be used, in a given configurable period, to authorize the user for collaboration services. This feature is designed to thwart inadvertent or real denial of service attacks, which can originate from multiple client devices authorizing the same user, or from clients that reauthorize more often than necessary.
How does Jabber verify the identity of Expressway E?
Jabber clients must verify the identity of the Expressway-E they are connecting to by validating its server certificate. To do this, they must have the certificate authority that was used to sign the Expressway-E's server certificate in their list of trusted CAs.
What is diagnostic log in Expressway?
The diagnostic logging tool in Expressway can be used to assist in troubleshooting system issues. It allows you to generate a diagnostic log of system activity over a period of time, and then to download the log.Before taking a diagnostic log, you must configure the log level of the relevant logging modules:
What are the two certificates for Cisco Unified Communications Manager?
The two Cisco Unified Communications Manager certificates that are significant for Mobile and Remote Access are the CallManager certificate and the tomcat certificate . These are automatically installed on the Cisco Unified Communications Manager and by default they are self-signed and have the same common name (CN). We recommend using CA-signed certificates for best end-to-end security between external endpoints and internal endpoints. However, if you do use self-signed certificates, the two certificates must have different common names. This is because the Expressway does not allow two self-signed certificates with the same CN. If the CallManager and tomcat self-signed certs have the same CN in the Expressway's trusted CA list, then it can only trust one of them. This means that either secure HTTP or secure SIP, between Expressway-C and Cisco Unified Communications Manager, will fail.
What is a mobile and remote access solution?
The mobile and remote access solution supports a hybrid on-premises and cloud-based service model, providing a consistent experience inside and outside the enterprise. It provides a secure connection for Jabber application traffic without having to connect to the corporate network over a VPN. It is a device and operating system agnostic solution for Cisco Jabber clients on Windows, Mac, iOS and Android platforms.
What is Cisco Unified Communications?
Cisco Unified Communications mobile and remote access is a core part of the Cisco Collaboration Edge Architecture. It allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging and presence services provided by Cisco Unified Communications Manager (Unified CM) when the endpoint is not within the enterprise network. The Expressway provides secure firewall traversal and line-side support for Unified CM registrations.
Do you need SIP trunks for Expressway?
Expressway deployments for mobile and remote access do not require SIP trunk connections between Unified CM and Expressway-C. Note that the automatically generated neighbor zones between Expressway-C and each discovered Unified CM node are not SIP trunks.
What is Expressway C?
Expressway-C automatically generates non-configurable neighbor zones between itself and each discovered Unified CM node. A TCP zone is always created, and a TLS zone is created also if the Unified CM node is configured with a Cluster Security Mode (System > Enterprise Parameters > Security Parameters) of 1 (Mixed) (so that it can support devices provisioned with secure profiles). The TLS zone is configured with its TLS verify mode set to On if the Unified CM discovery had TLS verify mode enabled. This means that the Expressway-C will verify the CallManager certificate for subsequent SIP communications. Each zone is created with a name in the format 'CEtcp-<node name>' or 'CEtls-<node name>'.
How does Jabber verify the identity of Expressway E?
Jabber clients must verify the identity of the Expressway-E they are connecting to by validating its server certificate. To do this, they must have the certificate authority that was used to sign the Expressway-E's server certificate in their list of trusted CAs.

Does Expressway-C support VPN?
VPN links, between the Expressway-C and the Unified CM services / clusters, are not supported. "Mixed" traversal connections are not supported. That is, we do not support traversal zones, or Unified Communications traversal zones, between Cisco VCS and Cisco Expressway even though it is possible to configure these zones. Explicitly, we do not support VCS Control traversal to Expressway-E, nor do we support Expressway- C traversal to VCS Expressway.
