Hi Michael,

> Therefore, I suggest to add some attributes, such as Listen Port, to support call-home.

I'm not entirely sure I follow you.   

Firstly, the draft is describing the NC/RC server initiating a protocol connection to a remote peer (the receiver).  So, in this since, it is "call home" already.

That said, maybe you mean "call home" in the sense of protocol-reversals (e.g., reverse TLS).  If so, note that the protocol being discussed here is more like Syslog than RESTCONF.   If it were Syslog, would you also to think there is a need to have a protocol-reversal?
