1. A method comprising:
- 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 dual tone multiple frequency (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.

Abstract
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.

9. An apparatus comprising:
-
a wireless network interface circuit configured for receiving an incoming wireless call; and a second circuit configured for responding to the incoming wireless call by causing the wireless network interface circuit to output a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call; the second circuit configured for determining whether enhanced services are available for the incoming wireless call based on 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; the second circuit further configured for 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus comprising:
-
a wireless network interface circuit configured for receiving an incoming wireless call; and means for responding to the incoming wireless call by causing the wireless network interface circuit to output a dual tone multiple frequency (DTMF) tone on a voice channel associated with the incoming wireless call; the means for responding configured for determining whether enhanced services are available for the incoming wireless call based on 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; the means for responding further configured for 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.

18. Non-transitory logic encoded in one or more tangible media for execution and when executed operates to:
-
receiving an incoming wireless call by a mobile node; determining by the mobile node whether enhanced services are available for the incoming wireless call based on outputting a dual tone multiple frequency (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 selectively initiating, by the mobile node, 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.
