Call forwarding on busy to an exchange#

Toggles the pbx-setting which redirects all incoming calls to a specific number when the user/phone already is in a call. Only for calls that arrive via a specific exchange line.

Uses feature-code: ##96 + exchange + #*67* + target + # + extention to activate forwarding and ##96 + exchange + ##67# + extention to deactivate.

Also creates a sip-subscription to the feature-code to fetch the state of this feature from the pbx.

  • green when Call forwarding is enabled to the target on the provided exchange
  • off when Call forwarding is disabled to the target on the provided exchange
  • solid orange on error, e.g. when sip dialog subscription to the feature-code did not work
  • orange blinking when subscription is being (re-)established
