How does a digital trunk board distinguish if the caller is calling 96588(operator) or 96588xxx (answering machine)?
This can be achieved for SS1 by enabling the multi-number interception function in the configuration file ‘ShConfig.ini’. As for SS7 and ISDN signaling, the application program itself makes the decision according to the called party number which the channel received after going into “pending” state upon receipt of a number with pre-determined length. For more details see ‘SynCTI Programmer’s Manual’.
