Refer to the exhibit. When a user tries to sign in to the Cisco Jabber client through Mobile and Remote Access, they receive this error message: “Cannot communicate with the server.” The external DNS server is configured with the SRV records listed in the exhibit.
What is the cause of the issue?
When using Mobile and Remote Access (MRA) for Cisco Jabber, the _cisco-uds DNS record should not be publicly resolvable. Instead, the collab-edge DNS record is required to route the traffic correctly through the Expressway servers. The absence of the collab-edge DNS record likely causes the communication issue reported by the user. Therefore, the solution is to add the collab-edge DNS record to the DNS server and remove the _cisco-uds DNS record, ensuring proper routing and connectivity for the Cisco Jabber client.
B seems correct, for MRA the cisco-uds record should not be resolvable via public DNS, and the collab-edge record is required
is the ANS correct ?
