Worth knowing
What this platform does and does not set
Read before you rely on every key
Only this phone's two fixed programmable keys (the ones Grandstream calls Fixed VPKs) are set by this platform today. Grandstream publishes those two keys' configuration values for the whole GRP range, but not the values for dynamic or expansion keys beyond them, so a third programmed key on this phone is not currently pushed by provisioning. It can still be set by hand on the phone, or reached through the pushed company directory.
Next
Set the matching DHCP option once on your own network, and every Grandstream phone you plug in after this one finds the platform on its own.
