Application not receiving GCEV_DROPCALL events

Symptom:

The symptom may be present with Dialogic® DMV series Media Boards using Dialogic® Global Call PDK protocols.

For INBOUND specific calls, after calling gc_DropCall on a connected/established call, the application may not receive a GCEV_DROPCALL event.

Reason for the issue:

This could potentially be a configuration problem.

For DMV series boards (DMV, DMVA, DMVB, etc.) there is a PDK-specific configuration requirement described in the "Global Call Country Dependent Parameters (CDP) for PDK Protocols" documentation:  if you disable IN_ANI, then the parameter feature_ANI should be removed from the SYS_FEATURES parameter.

Solution:

The following modification to the protocol specific cdp file should address this:

At the top of the IN & OUT ANI Enablement list, it states the following:

/* Caution: For DM3, you also have to remove feature_ANI from the */
/* SYS_FEATURES parameter if ANI is disabled */

If you have your ANI enablement disabled (0) within your cpd file:

All BOOLEAN_t CDP_IN_ANI_Enabled = 0
All BOOLEAN_t CDP_OUT_ANI_Enabled = 0
All BOOLEAN_t CDP_IN_ANI_ST_Needed = 0
All BOOLEAN_t CDP_OUT_ANI_ST_Needed = 0
All INTEGER_t CDP_IN_ANI_MaxDigits = 0

REMOVE 'feature_ANI' from the feature list further below within the cdp. It should look like the following:

/* enable features */
/*
All CHARSTRING_t SYS_FEATURES = "feature_outbound,feature_inbound,feature_DNIS,feature_transfer,feature_hold"
*/
