What is Dialed in channels.json?

[lenz.loway at gmail.com (Lenz Emilitri)]

Auto-generating code from channel.json I find a "Dialed" model that
has no field and inherits nothing. What is that?

It's defined as:

{
"properties": {},
"id": "Dialed",
"description": "Dialed channel information."
}

TIA
