EXP40 BLF not working

[stavros]

I'm having trouble with BLF on an EXP40. The BLF configured on the T46G works, but not on the EXP40. I can press the appropriate key on the EXP40 and it dials the extension 1159, but BLF doesn't work.

Freepbx doesnt show extension being watched when its configured on the EXP40.

#works
linekey.4.type = 16
linekey.4.line = 1
linekey.4.value = 1159
linekey.4.label = John
linekey.4.extension = %NULL%
linekey.4.xml_phonebook = %NULL%
linekey.4.pickup_value = **

#doesn't work
expansion_module.1.key.24.type = 16
expansion_module.1.key.24.line = 1
expansion_module.1.key.24.value = 1159
expansion_module.1.key.24.label = John
expansion_module.1.key.24.pickup_value = **
