Enable/disabling hidding my CallerID for outgoing calls

Hi,

we configured some Mita 6867i hard phones fine with FreePBX EPM (Endpoint manager).

Now, i try to configure one of the Mita’s softkeys to toggle between enable/disable showing my caller id on an outgoing call (CLIR - calling line identification restriction). The state of the softkey should reflect the state of hiding/showing my outgoing CLID.

Is there a way to configure this requirement?

Independent of the softkey, i can’t figure out how to setup a new “featurecode” (e.g. *999) which enable/disable (toggle) showing my CLID on an outgoing call from my extension?

Maybe somebody can help me on the right track?

Best Regards
Daniel
