No, this is definitely an issue with the chan_unistim.
- Grandstream GXP2000 runs its own local SIP client, which has local
client control over all sorts of hardware settings, including LED state.
- On a phone running Unistim (similar to other "thin" protocols), there
are almost no local-client options on the phone setup; Everything is
directly handled by the call server.  The call server sends all messages to
the display, interprets buttons pressed, and tells the phone what tones to
play, or what audio stream to start.  Using thin clients on the phones
allows centralized control (a single change at the server doesn't mean
walking around and adjusting all of the clients, and the phone can support
a wide range of user-interfaces, depending on what it is plugged in to).
