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
The current template itself for this key-type can be found here.
The key-type has the following parameters:
The identity the key is tied to. Only active identities can make calls or send sip-subscriptions.
The exchange line access number (account number) that identifies the exchange.
The target where forwarded calls are redirected to.
