Worth knowing
What this platform does and does not set
Read before you rely on every key
This phone has 56 programmable keys, but only the two Fixed VPKs (the two keys Grandstream publishes values for across the whole GRP range) are set by this platform today. The other 54 are not provisioned automatically. Confirm a per-model key map against Grandstream's own configuration template before relying on this phone's full key panel out of the box.
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.
