Change Active Line
With DeskPhone device, if it has more then one telephony line it can use, choice can be made which one will be used. List of available telephony lines can be retrieved, but only once deskphone has been connected with CUCM. New active line can be selected through DeskPhone.selectLine method, as it is shown in the snippet bellow:
// For the sake of this example we'll assume that we have 3 available lines [1111, 1112, 1113]
var telephonyLines = deskphone.lineDirectoryNumbers;
// We'll select line 1112.
var telephonyLineToSelect = telephonyLines[1]
deskphone.selectLine(telephonyLineToSelect);
