You can. Make sure FaceTime is enabled on iPhone.
See this troubleshooting document: http://support.apple.com/kb/TS3367
Note that if you are trying to use cellular data on either device cellular data must be enabled and explicitly enabled for FaceTime usage. Also check with your carrier to see if they have any restrictions on FaceTime usage.
