I have known problem -8072 error while data call communication between N95 8GB(3rd FP1) and N79(3rd FP2). While searching, I have found some links.
Problem outline: lack of modem tuning capabilities on Nokia phones
*Connection Error when using Data Call (CSD) line
*Known error: KIS000999 - Error -8072 in Nokia wikiIn this presentation, 5pro-software have solved the problem with the help of source code of symbian.Problem solution: Symbian Open Source
*Symbian sources become available
*CSD parameters become available
*List of errors becomes available
*CSD parameters can be changed and the reason for problem is found!
So, defintion of -8072 is under
sf/os/cellularsrv/telephonyserverplugins/common_tsy/commontsy/exportinc/serviceapi/GsmError.hI think this error is thrown fromconst TInt KErrGsmBusyUserRequest = KErrPhoneSpecificGsmCallBase - 22; // -8072
Any solution or sugesstion about this problem, please?
