<br><br>On the Grandstream I have to configure the expansion car buttons as "Asterisk BLF" buttons, even though "BLF" (busy lamp field) isn't an Asterisk setting that I turn on. To enable BLF functionality in Asterisk, I have to set up hints in the dialplan and configure the user agent to subscribe to status notitications for those extensions.
<br><br>I'd search for asterisk user testimonials to be safe (assuming nobody steps up and says "I got that working"). Often times you'll find someone's blog about how they got a feature working with a particular piece of hardware, along with configuration samples.
