From Cisco Document for Expressway , DNS Records requirements , say for example :
For Public DNS :-
- Service : collab-edge
- Protocol : tls
But in the table , they did not mention to prefix " _ " (underscore) with collab-edge or tls. Am confused do I have to manualy add "_" (underscore) before collab-edge while filling SRV Records or it takes automatically ?
Similarly for cisco-uds , tcp , tls , cuplogin etc. Please clarify ?
