Apparatus and methods concerning call routing are disclosed. In an example embodiment, a call alert message, indicative of the call answer options, is communicated from a data-communications server to the communication device, determined in response to receiving an incoming call for a communication device at the server. A selected option is received from the communication device. In response to the selected option indicating the first call answer option, the call is routed to the communication device as a call via a data network or in response to the selected option indicating the second call answer option, the call is routed to the communication device via a PSTN.
