Explanation

When Cisco Jabber is on the corporate network (internal), it uses the User Data Service (UDS) for service discovery. The DNS SRV record _cisco-uds._tcp.domain.com tells Jabber where to find the Cisco UCM UDS endpoint, enabling automatic provisioning of server addresses, UC services, and IM&P settings. The _tcp transport is used because UDS operates over HTTP/HTTPS (TCP), not TLS at the SRV level. Option B (_cisco-uds._tls) is not the correct record name for UDS discovery. Options A and D (_sip._tcp / _sip._tls) are used for SIP endpoint registration, not Jabber service discovery.
