speech call originated on that line. However, 3.1 kHz audio information transfer capability is allowed on data lines (modem or fax) by most switches. S55 also lets you define whether a progress indicator information element (which indicates that the origination address of the POTS call is non-ISDN) is sent with the SETUP message for the POTS port call. This may help POTS port calls get through certain CO switches.

Modifies the value of Octet 3 of the Calling Party Number Information Element that is sent within the SETUP message for data and POTS port (voice/modem/fax) calls. To set a specific number type and numbering plan, select an option from the Type of Number section above and add its value to the value of an option in the Numbering Plan section above. For example, a National/ISDN Calling Party Number IE would be S56=33, where 32 (National) + 1 (ISDN/telephony) = 33 (National/ISDN). If there is no Data Directory Number (for data calls) nor Voice Directory Number (for voice/modem/fax calls), no Calling Party Number IE is sent. By
