/mcpDWORD m_AffectedDeviceID[10]: TSP returns this value. It contains the list of deviceIDs for any device that is affected by this call. Do not call lineDevSpecific for any other device in this list. DWORD m_mediaCapCount The number of codecs that are supported for this line. MEDIA_CAPS m_MediaCaps - A data structure with the following format: typedef struct { DWORD MediaPayload; DWORD MaxFramesPerPacket; DWORD G723BitRate; } MEDIA_CAPS[MAX_MEDIA_CAPS_PER_DEVICE]; This data structure defines each codec that is supported on a line. The limit specifies 18. The following description applies for each member in the MEDIA_CAPS data structure: MediaPayload is an enumerated integer that contains one of the following values. enum{ Media_Payload_G711Alaw64k = 2, Media_Payload_G711Alaw56k = 3, // "restricted" Media_Payload_G711Ulaw64k = 4, Media_Payload_G711Ulaw56k = 5, // "restricted" Media_Payload_G722_64k = 6, Media_Payload_G722_56k = 7, Media_Payload_G722_48k = 8, Media_Payload_G7231 = 9, Media_Payload_G728 = 10, Media_Payload_G729 = 11, Media_Payload_G729AnnexA = 12, Media_Payload_G729AnnexB = 15, Media_Payload_G729AnnexAwAnnexB = 16, Media_Payload_GSM_Full_Rate = 18, Media_Payload_GSM_Half_Rate = 19, Media_Payload_GSM_Enhanced_Full_Rate = 20, Media_Payload_Wide_Band_256k = 25, Media_Payload_Data64 = 32, Media_Payload_Data56 = 33, Media_Payload_GSM = 80, Media_Payload_G726_32K = 82, Media_Payload_G726_24K = 83, Media_Payload_G726_16K = 84, // Media_Payload_G729_B = 85, // Media_Payload_G729_B_LOW_COMPLEXITY = 86, } Media_PayloadType; MaxFramesPerPacket should read as MaxPacketSize and comprises a 16 bit integer that is specified in milliseconds. It indicates the RTP packet size. Typically, this value gets set to 20. G723BitRate comprises a six byte field that contains either the G.723.1 information bit rate, or gets ignored. The values for the G.723.1 field comprises values that are enumerated as follows. enum Cisco Unified TAPI Developers Guide for Cisco Unified Communications Manager, Release 15 and SUs 361 Cisco Device-Specific Extensions Parameters
