Signal emitted when a remote caller is invoking the <link linkend="gdbus-method-org-freedesktop-ModemManager1-Modem-Voice.
ListCalls">ListCalls</link> D-Bus method.
If a signal handler returns true, it means the signal handler will handle the invocation (e.g. take a
reference to invocation and eventually call
complete_list_calls or e.g. return_error on it)
and no other signal handlers will run. If no signal handler handles the invocation, the
g_dbus_error_unknown_method error is returned.
