This plugin is supported from the current Linphone 4.2.2

Linphone Plugin is a Locale/Tasker plugin to activate or deactivate sip accounts on the Linphone app

You can now enable/disable accounts based on your wi-fi connection, your location, the time of day, and so on.

Install Tasker, then install this plugin to add a Linphone Plugin task to Tasker to allow you to enable/disable linphone accounts.

If you want to change your extension depending on whether you are in or out of the office you now can.
If you want to turn off your sip phone out of hours you now can.

Hint: If you are disabling one account and enabling another, perform the enable FIRST so the default account moves
i.e. always enable THEN disable.
