Grandstream IP Phones work well in combination with the Axeos PBX.
We have added the required settings for the Busy Lamp Field (BLF) support in Axeos IP PBX release 3.0.
On the phone enter the fysical phone ID, for example: 200 (don't use 200@IPADDRESS)
BLF is a phone feature. On the (v)PBX the inbound number should be linked to the physical phones, not the PBX users.
The (v)PBX administrator chooses either BLF or Presense/Hotdesking.
NOTE: Call forwarding (*72) is also a local phone function and may conflict with the (v)PBX *72 function.
