CallScripter releases prior to 4.5.25, and some of the features within them are no longer actively maintained and developed.  Whilst we operate a best endeavours promise to support customers on these these older versions of our products, we are unfortunately unable to carry out any further maintenance of the underlying code base.  We understand that it is not always possible for our customers to upgrade to the latest version of our products, and where possible, the support team will always attempt to provide a work-around to any issues raised.
