Helpdesks do not need to be purely physical objects but instead can be virtual. Problems can be reported and replies returned via email. Text-based and audio chat systems that enable people to interact with a human without using a phone can also be used.
Self-help systems are also popular but should not be considered replacement for systems that involve human interaction. With the pervasiveness of the web, there is no excuse not to have at least a simple repository of documentation for customers on such topics as how to get help or request service activation and solutions to common problems. A simple single-page web site with links to important documents, a wiki, or even a searchable blog (one post per FAQ) can be used. Web - based systems let customers help themselves by offering documentation, lists of frequently asked questions and their answers, and just-in-time help. These systems can reduce the workload of helpdesk attendants but cannot provide the interactive debugging and workflow issues that require real-time interaction. There should be a phone number to call to report that the self-help system is down.
