Initiating a wireless communication session from contact information on a computer

A communication session between a wireless communication device and one or more recipient communication devices is initiated in response to user input received at a separate computing device. The intended parties of the call are identified at the computing device in response to the user input. Once the intended parties have been identified, the calling instructions are generated and transmitted to the wireless communication device or a server, which cause a call to be initiated between a wireless communication device and one or more recipient communication devices. This allows a caller to utilize the functionality and resources available on a computer to initiate a call, while enabling the caller to utilize the functionality and resources available on the caller's wireless communication device to engage in and complete the call, without requiring the caller to communicate through the telephony applications of a computer.
