Just like issue 31 the Call class doesn't implement the __construct function correctly according to the abstract definition in the BaseClass.
Since there are apparently some other issues with this (this is the only class I've had issues with) I would suggest commenting out the definition in BaseClass for the __construct function. This is what I did to fix the issue so that if any other classes have the issue it won't matter since there is no longer a required definition for it.
