Public DNS
The public (external) DNS must be configured with _collab-edge._tls.<domain> SRV records so that
endpoints can discover the VCS Expressways to use for mobile and remote access. SIP service records are
also required (for general deployment, not specifically for mobile and remote access). For example, for a
cluster of 2 VCS Expressway systems:

Ensure that the cisco-uds and _cuplogin SRV records are NOT resolvable outside of the internal

Expressway.
