This section provides you with conversion information between Pakistan (ISUP) and ITU (ISUP).
Pakistan (ISUP) to ITU (ISUP)
The Charge (CRG) message is used in Pakistan as a response to an Initial Address Message (IAM).
The CRG message returned for received IAM does not include the optional Number of Charging Units parameter as that parameter is used for meter pulse generation. The Level 4 Converter does not generate meter pulses for this conversion.
The following table provides you with the Pakistan (ISUP) to ITU (ISUP) message conversion details.
