i want to develop a S90 application that need to call , listenincomingcall and send DTMF , if i need a ACS Publisher ID .
i see in S60 3nd FP2 SDK example IsvTelCallApp
"This application requires following capabilities defined in IsvTelCallApp.mmp:
NetworkServices ReadDeviceData WriteDeviceData ReadUserData WriteUserData
ACS Publisher ID is required to sign applications with ReadDeviceData and WriteDeviceData. However, a signed sis is provided in sis-folder so that this example application can easily be tried on a device.
