In one embodiment, a method comprises a mobile node receiving an incoming wireless call; the mobile node determining whether enhanced services are available for the incoming wireless call based on outputting a DTMF tone on a voice channel associated with the incoming wireless call and determining whether a notify message, indicating a server providing the enhanced services has received the DTMF tone, is received on a data channel during the incoming wireless call; and the mobile node selectively initiating the enhanced services for the incoming wireless call with the server in response to determining the enhanced services are available for the incoming wireless call.
