T28P + EXP39

[cmcoke]

Using BroadWorks, I am trying to configure an EXP39 that is connected to a T28P with the default configuration file of the T28P. The problem that I am facing is that whenever I try to configure a user for line 4, the configuration does not show up on the EXP39. Stated below is an example of the configs

#Each expansion module1 key1
expansion_module.1.key.1.type = 13
expansion_module.1.key.1.line =
expansion_module.1.key.1.value = 1234
expansion_module.1.key.1.pickup_value =
expansion_module.1.key.1.label = User One
expansion_module.1.key.1.xml_phonebook =

#Each expansion module1 key2
expansion_module.1.key.2.type = 13
expansion_module.1.key.2.line =
expansion_module.1.key.2.value = 5678
expansion_module.1.key.2.pickup_value =
expansion_module.1.key.2.label = User Two
expansion_module.1.key.2.xml_phonebook =

#Each expansion module2 key3
expansion_module.1.key.3.type = 13
expansion_module.1.key.3.line =
expansion_module.1.key.3.value = 9011
expansion_module.1.key.3.pickup_value =
expansion_module.1.key.3.label = User Three
expansion_module.1.key.3.xml_phonebook =

#Each expansion module1 key4
expansion_module.1.key.4.type = 13
expansion_module.1.key.4.line =
expansion_module.1.key.4.value = 9012
expansion_module.1.key.4.pickup_value =
expansion_module.1.key.4.label = User Four
expansion_module.1.key.4.xml_phonebook =

What could be the problem and solution of this?
