Open Source - How can I change the Line Key name using DPMA

The information displayed on the line keys of the Sangoma Phones is defined by the Line Configuration option 'line_label'. By default or if the option is empty, the phone is going to show the extension number.

For example:

[bob101]

type=line

digit_map=[0-8]xx

line_label=BobbyJ

mailbox=bob101

Further information about DPMA configuration can be found here.
