Defining the VN4 SubroutinesCertain combinations of parameters can cause special occurrences inthe toolkit. They are shown in Table 10-3:Table 10-3. Combinations in VN4_TRANSFER_STARTConflicting ParametersParameter 3 – Transfer ModeandParameter 5 – Answering MachineDetectionParameter 3 – Transfer ModeandParameter 5 – Answering MachineDetectionDescriptionSelecting 1 (Transfer in Alerting State)in Parameter 3 and then selecting 1(Detect answering machine) inParameter 5 causes the system todisregard answering machinedetection.The toolkit automatically turnsParameter 5 OFF. The call must firstbe answered so that an answeringmachine can be detected.Selecting 2 (Transfer in AnsweredState) in Parameter 3 and thenselecting 1 (Detect answeringmachine) in parameter 5 is a validchoice of Parameter entries.However, the transfer may occurslowly.After the line is answered, the OmviaMedia Server must determine if theanswer was live or an answeringmachine. The determination can takeup to 10 seconds to complete.If Answering Machine Detection is notnecessary, select 2 in parameter 5 forquicker processing.Return Values:See Table 10-4.60001262, First Edition VN4 ISDN Protocol 10-7
