I am currently in the process of evaluating 3CX for my company's use (30 phones, 8 PSTN lines with the plans to go VOIP in the future). I am testing it with Grandstream GXP-2000 phones and a GXW-4108 gateway. One thing that would be of great use would be to add an extension module to the receptionist phone to take advantage of the Busy Lamp indicators for every extension. Is this currently supported on the 3CX system? I haven't found any mention of it in the docs or on the forums. Also, I've seen it mentioned on here a few times, but any word on when the MWI will be supported? That would be another feature to get the boss to pull the trigger and sign the order to get the paid version of the system. Thanks for any info you can share.
