Public DNS
The public (external) DNS must be configured with _collab-edge._tls.<domain> SRV records so that
endpoints can discover the Expressway-Es 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 Expressway-E systems:
