At a telephony service location remote from a caller and a call recipient, a request for establishing a connection to the call recipient is received. The request is initiated by the caller specifying a number associated with the call recipient. A call recipient originated command signal is received during a call connected phase, the call recipient originated command signal being a single command that is interpreted by the telephony service without the necessity of any additional command being sent. In response to receiving the call recipient originated command signal, a service or transaction is initiated between the caller and the call recipient other than a standard call connection transaction. The call recipient originated command signal is received from a communication device of the call recipient.
