We have a whole bunch of GXP 2000 phones here but now we're growing too big for just 4 incoming lines. We use Trixbox (asterisk) for the phone system with 4 analog lines coming into a Dell server.
Is there a way that these Grandstream GXP 2000 phones can handle 8 lines? How does that work? Is there some kind of configuration that can be done in Trixbox when we do move to 8?
