Can Expressway-E support multiple external domains for MRA?
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:
Do I need an IP address or FQDN for Expressway?
If Unified Communications Manager and Expressway are in different domains, you must use either IP addresses or FQDNs for the Cisco Unified Communications Manager server address.
Does Expressway support IPv6 MRA traffic?
In the case of "Both", as Expressway does not proxy IPv6 MRA traffic from clients, intermittent issues may arise if clients send IPv6 instead of IPv4. Endpoint management capability (SNMP, SSH/HTTP access) is not supported.
Do IP phones need clustered Expressway servers?
IP Phones need at least the same number of Expressway-C and Expressway-E servers in the cluster as the number of Unified CMs in the Call Manager group configured on the IP phone. Note that devices running TC or CE software don't need clustered Expressway servers for Unified CM failover.
What is mobile and remote access?
The Mobile and Remote Access solution (MRA) supports a hybrid on-premises and cloud-based service model. This provides a consistent experience inside and outside the enterprise. MRA provides a secure connection for Jabber application traffic without having to connect to the corporate network over a VPN.

How does Jabber verify the identity of Expressway-E?
Jabber clients 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 happens if one Expressway node fails?
Currently, if one Expressway node in a clustered deployment fails or loses network connectivity for any reason (including if the Unified CM restarts or fails), all active calls going through the affected node will fail. The calls are not handed over to another cluster peer. Bug ID CSCtr39974 refers. This is not an MRA-specific issue and applies to all call types.
What is MRA domain?
MRA domain (s). The domain (s) configured on Expressway and enabled for Unified CM registration
What domain must the calls be routed to?
The domain to which the calls are routed must match with the MRA domain to which the endpoints were registered. For example, if endpoints are registered with the domain exp.example.com, the calls must be routed to this domain, and it must not be routed to the domain cluster1.exp.example.com .
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.
Does Jabber use Expressway C?
Deployments that require Jabber clients to always connect over MRA also benefit from the X12.5 update that no longer requires the Expressway-C to resolve the _cisco-uds DNS SRV record. So administrators only need to configure the _collab-edge DNS SRV record, and Jabber clients using service discovery will only have the option of connecting over MRA.
Does Cisco Expressway support SRV?
From X12.5, the Cisco Expressway Series supports the case where MRA clients use an external domain to lookup the _collab-edge SRV record, and the _cisco-uds SRV record for that same external domain cannot be resolved by the Expressway-C. This is typically the case when split DNS is not available for the external domain. And prior to X12.5 this required a pinpoint subdomain or some other DNS workaround on the Expressway-C, to satisfy the client requirements for resolving the _cisco-uds record.
