Limiting / Configurating number of lines Available/Enabled to GUI

[fredcwbr]

I need to limit Twinkle to 1 user line. It can be by disabling line 2 or if there is some preprocessor or CMake glue to configure line generation. ,

Is that already in Twinkle 1-10.{2|3} ? or would there be some roadmap here?

I tried this, but it didn't seem to work.,

// Number of phone lines
// One line is used by Twinkle internally to park the call towards a
// referrer while the refer is in progress.
// Besides the lines for making calls, ephemeral lines will be created
// for parking calls that are being released. By parking a releasing
// call, the line visible to the user is free for making new calls.
#define NUM_CALL_LINES 2 // Total numbers of phone lines for making calls
#define NUM_USER_LINES 1 // #lines usable for the user

#define LINENO_REFERRER 1 // Internal lineno for referrer

Thanks in advance,
