We receive messages today through multiple channels such as telephone, texts, emails, social media posts etc. and can struggle to prioritize, miss messages, etc. which can impact sales, service, and other customer orientated activities within businesses, service providers etc. Embodiments of the invention exploit a communication model wherein the conventional delay is augmented with filters, recirculating delay lines, decision circuits and loads to exploit an electrical analogy. This model allows different priority messages to be handled and recognizes that messages have different priorities associated with them and that these priorities are dynamic and do not necessarily depend solely upon the sender and recipient but also the context of that communication within an overall activity. Beneficially, the model is compatible with a variety of enterprise software tools including, but not limited, lead management (LM), sales management (SM), customer relationship management (CRM), as well as electronic mail and other communication tools etc.
