Explanation
When a Jabber user enters [email protected] as their login ID, Jabber performs an MRA (Mobile and Remote Access) edge discovery using the DNS SRV record _collab-edge._tls.<domain>. In this case, that resolves to _collab-edge._tls.cisco.com. This record points Jabber to the Expressway-E server for secure MRA connectivity. The _cuplogin._tcp record is a legacy Cisco Unified Presence login record. The _cisco-uds._tcp and _cisco-uds._tls records are used for internal UDS (User Data Service) discovery on Cisco UCM, which is only reachable inside the corporate network, not externally via MRA.
