What is a single domain?
A single domain means that you have a common domain ( example.com) with separate internal and external DNS servers. This allows DNS names to be resolved differently by clients on different networks depending on DNS configuration, and aligns with basic Jabber service discovery requirements.
Does Cisco Expressway work with multiple domains?
Cisco Expressway supports Mobile and Remote Access with multiple external domains. With this deployment, you will have more than one external domain where your MRA clients may reside. Expressway-E must be able to connect to all of them. To configure this deployment, do the following:
Can you use CMS and MRA on the same Expressway?
If you use both the CMS Web Proxy service and MRA on the same Expressway, the following configuration items must be assigned different values per service. If you try to use the same value, the service that was configured first will work, but the other one will fail:
Can MRA have a single domain?
The ideal scenario for MRA is to have a single domain with a split DNS configuration, and this is the recommended approach. This is not always possible , so there are some other approaches to deal with various alternative scenarios.
Can you have multiple domains on Expressway C?
As of X8.5, you can create multiple deployments on the Expressway-C, but this feature is still limited to one domain per de ployment. As of X8.5.1, a deployment can have Multiple Presence Domains. However, this feature is in preview status only , and we recommend that you do not exceed 50 domains.
Can Jabber guest use Expressway?
The Expressway cannot be used for Jabber Guest when it's used for Mobile and Remote Access (MRA). The Expressway-C used for MRA cannot also be used for Microsoft gateway service. Microsoft gateway service requires a dedicated Expressway-C. Maintenance mode is not supported over MRA for endpoints running CE software.
What is a basic network access?
Basic network access for mobile devices, such as smartphones and tablets, includes email, calendar, and contacts. These capabilities can be provided securely without requiring the use of a VPN client by deploying gateway technology in the demilitarized zone (dMZ) and configuring the required firewall security policies.
What is Cisco CVD?

They incorporate a broad set of technologies, features, and applications to address customer needs. Cisco engineers have comprehensively tested and documented each CVd in order to ensure faster, more reliable, and fully predictable deployment.
What is TNd in Cisco?
The Trusted Network detection (TNd) feature of Cisco CWs determines whether a host is connected directly to a trusted network, in this guide referring to a LAN or WLAN at an organization’s primary or remote sites. Conversely, if a host connects to an organization through a remote access VPN, then the host is considered to be on an untrusted network.
How does intelligent routing affect the internet?
This load increase can raise costs. intelligent routing of traffic is a priorit y to control which traffic from a user has to go through the internet edge component of the organization’s network and which traffic can be kept out on the internet. Reducing security on this traffic is not an option that is readily available. Traffic destined for the internet that has to be brought back to the internet edge for security inspection increases bandwidth usage and load on the internet edge design, while increasing latency on user connections.
Why do organizations need to allow access to the network?
As users move outside the boundaries of the traditional network, their requirements for access to job-related data, such as email, calendars, and more, don’t change. in order for people to be productive, organizations need to allow them access to the network from wherever they are and to whatever data they need, using any device the organization allows. At the same time, organizations must ensure that all access to the network is secure and appropriate and that it follows organizational guidelines.
Does ActiveSync support a single DNS?
This process assumes that a resilient internet connection is used. Activesync is available on either isP using different iP addresses. This solution does not support the use of a single dNs name for resiliency. if there is a failure of the primary isP (isP-A), you must manually update the dNs name to refer to the secondary isP address.
Can Cisco AnyConnect VPN be replicated?
When running an RA VPN Cisco AsA firewall pair, the Cisco AnyConnect VPN Profile file and the Web security service Profile files must be manually replicated to the secondary AsA firewall. All of the files listed in Table 1 must be replicated.

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.
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 Expressway CSR?
The Expressway certificate signing request (CSR) tool prompts for and incorporates the relevant subject alternate name (SAN) entries as appropriate for the Unified Communications features that are supported on that Expressway.
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.
Why do I need to associate a domain with an IDP?
You need to associate a domain with an IdP if you want the MRA users of that domain to authenticate via the IdP. The IdP adds no value until you associate at least one domain with it.
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.
Background
Proper troubleshooting technique requires that you have a thorough understanding of how things should work during normal operations. I presented on the MRA registration process during a NetCraftsmen Cisco Mid-Atlantic User Group (CMUG) meeting last year.
Service Discovery
Upon initialization, the Jabber client enters into a “Service Discovery” mode. At this stage, the client is trying to determine if it is inside the corporate network or outside. The mechanism that is used is DNS. Specifically, the Jabber client will query for specific DNS service records (SRV record) based on the assigned service domain.
Service Provisioning
Once the client establishes a TLS connection to port 8443 on the Edge appliance, the user credentials are authenticated. At this point, the proxy connection is established and the client will start downloading configuration information from the UCM cluster. This configuration information is used to complete the service registration phases.
XMPP Registration
If the Jabber client is provisioned for IM&P presence services, the client will attempt to establish a connection on TCP port 5222. Registration requests are sent to the Edge appliance, which then proxies the transaction through the Core appliance to the IM&P cluster node (s).
SIP Registration
If the Jabber client is provisioned as a voice/video soft phone, the client will attempt to establish a connection on TCP port 5061. Registration requests are sent to the Edge appliance, which is then proxied through the Core appliance to the UCM cluster node (s). Successful registration is required for voice/video call functionality.
Visual Voicemail
If the Jabber client is provisioned with visual voicemail, the Jabber client will submit registration requests to the Edge appliance using the already established TLS connection on port 8443. The Edge appliance proxies the request through the Core to the REST API on Unity Connection.
Service Discovery
This step is fairly straightforward. We need to determine if the client can resolve the proper DNS SRV records. Using dig or nslookup, verify that the client can resolve the collaboration edge SRV records. For example:
What is the maximum bit rate for video calls on Cisco Unified Communications Manager?
The Maximum Session Bit Rate for Video Calls on the default region on Cisco Unified Communications Manager is 384 kbps by default . The Default call bandwidth on Expressway-C is also 384 kbps by default. These settings may be too low to deliver the expected video quality for MRA-connected devices.
What is a single domain?
A single domain means that you have a common domain ( example.com) with separate internal and external DNS servers. This allows DNS names to be resolved differently by clients on different networks depending on DNS configuration, and aligns with basic Jabber service discovery requirements.
