/mcpValue Parameter The size, in bytes, of the variably sized field containing the Hunt Pilot Partition, and the offset, in bytes, from the beginning of LINECALLINFO data structure. ConnectedPartyHuntPilotPartitionOffset ConnectedPartyHuntPilotPartitionSize This field specifies whether the call is a chaperone call or not. IsChaperoneCall To indicate that partition information exists in the LINECALLINFO structure, the system fires a LINECALLINFOSTATE_DEVSPECIFIC event. The bit map indicating the change is defined as the following: 0x00000001 SLDST_SRTP_INFO 0x00000002 SLDST_QOS_INFO 0x00000004 SLDST_PARTITION_INFO 0x00000008 SLDST_EXTENDED_CALL_INFO 0x00000010 //M&R SLDST_CALL_ATTRIBUTE_INFO 0x00000020 //M&R SLDST_CCM_CALL_ID 0x00000040 //SecureConf SLDST_SECURITY_STATUS_INFO 0x00000080 //CPN SLDST_NUMBER_TYPE_CHANGED 0x00000100 //CPN SLDST_GLOBALIZED_CALLING_PARTY_CHANGED 0x00000200//IPv6 new SLDST_FAR_END_IP_ADDRESS_CHANGED 0x00000400 SLDST_UNIQUE_CALL_REF_ID_INFO 0x00000800 SLDST_DEVICE_VIDEO_CAP_INFO 0x00001000 SLDST_MULTIMEDIA_STREAMS_INFO LINEDEVSPECIFIC{ hDevice = hcall //call handle for which the info has changed. dwParam1 = SLDSMT_LINECALLINFO_DEVSPECIFICDATA //indicates DevSpecific portion’s changed dwParam2 = SLDST_SRTP_INFO | SLDST_QOS_INFO |SLDST_PARTITION_INFO | SLDST_EXTENDED_CALL_INFO | SLDST_CALL_ATTRIBUTE_INFO|SLDST_CCM_CALLID| SLDST_CALL_SECURITY_STATUS | SLDST_NUMBER_TYPE_CHANGED | SLDST_GLOBALIZED_CALLING_PARTY_CHANGED | SLDST_FAR_END_IP_ADDRESS_CHANGED | SLDST_UNIQUE_CALL_REF_ID_INFO | SLDST_DEVICE_VIDEO_CAP_INFO | SLDST_MULTIMEDIA_STREAMS_INFO dwParam3 = … dwParam3 will be security indicator if dwParam2 has bit set for SLDST_SRTP_INFO } Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 342 Cisco Device-Specific Extensions Parameters
