Grandstream GXP and GRP Phones going Offline Daily

[bcarrico]

We have started checking "online" extensions first thing in the morning through the 3CX Management Interface because we have to reboot Grandstream phones so much. They just show go offline. A reboot of the phone fixes the issue every time. We even have the client "factory reset" their phones when they notice it. It has become a real pain. Is this something known between 3CX and Grandstream? Or could it be something on my end? The configuration is mixed between SBC's and VPN. We have very few Direct SIP units. I don't have any of these issues with other phone manufactures.
