[Asterisk-Users] snom and "hint" priority

[Karl Brose]

The hint feature is not a well developed general status monitor, it's 
just a *static* method to define the state of an extension as the state 
of a device for those channel drivers that support the extension state 
"API".
It can't be dynamically changed (it's not an executable dialplan 
element, like an application), and by implementation it is an extension 
state, not more.
