Communication systems and methods are described that include class-based call request routing. Components of the communication systems are configured to receive information of a class at a calling device. In response to the class information, a call request is automatically generated and addressed to resources of a class group. The resources of the class group all possess a common attribute of the class. The attribute includes one or more of a skill, job specialty code, job title, company, department, and division. The generated call request is routed to target devices of the resources. In response to a resource accepting the call request, a response message is received from a target device of the resource. Communications are established between the calling device and the at least one target device in response to the response message received from the target device.
