If anyone can help me Ill appreciated it. My configuration is as follows Yeastar S100 with Grandstream GXP2160 phones, 8 Fxo Lines.
What we need is set the BLF keys to each trunk like in old Analog Panasonic systems to be displayed if the Trunk line is flashing and been able to pick it up.
By now i am able to set the BLF button to an specific line I can see when is avaible (green) and when is busy (red), but I am unable to pick it up.
If some one can help me or had some similar issues, in the GXP2160 phones there should be something like a BLF pickup but its not working picking up the line trunk.
