Call Control API Messages

SwitchKit Name

CPCDetection

Type

EXS API and SwitchKit API message

Description

This message enables or disables the detection of CPC (Calling Party Control), which is needed on FXO/LS channels. CPC is the means by which the calling end notifies the called end that the established connection is no longer needed. In this case, dialtone is used for notification.

This feature can only be activated if the Excel platform contains an MFDSP or DSP-ONE card with at least one DSP configured for Call Progress Analysis. When CPC is detected, it is reported to the host in a Call Processing Event message.
