Has anybody tried/tested the new firmware for the Grandstream GXP2000/2020 phones or the GXW4104/4108 gateways? They currently have v220.127.116.11 in Beta for the phones and v18.104.22.168 for the gateways. The phone firmware should fix the MWI problems and random lockups of phones. The gateway firmware is supposed to fix the problems with random dropped calls. These are issues that I have seen a few posts about on the boards here. Does 3CX test the firmware of partner hardware vendors?
