Abstract
The present invention allows a terminating telephony switch to detect whether or not a caller associated with an incoming call is associated with multimedia capability. The terminating telephony switch will monitor a call setup message, such as an Integrated Services User Protocol Initial Address Message, to determine whether or not there is multimedia capability information indicative of the caller's telephony terminal being associated with another media device, or including media capability sufficient to support packet sessions over a data network. The multimedia capability information may simply be the presence or absence of a flag, wherein the presence of a flag indicates there is multimedia capability. Alternatively, the call setup message may include the multimedia address associated with the media device of the caller. The originating telephony switch is configured to create call setup messages to provide multimedia capability information to enable the functionality of the terminating telephony switch.
