MediaEncryptionKeyInfo Cisco TSP reports a detailed multimedia Encryption Key Information to the applications as a part of the structure CiscoTsp_MultiMediaEncryptionKeyInfo, if there is secure connection to CTIManager. The application user is authorized to receive multimedia Encryption Key Information. The multimedia Encryption Key information that is provided by Cisco TSP includes TxKeylen, RxKeylen, Txkey, RxKey, TxSalt, RxSalt, AlgorithmID, TxIsMKIPresent, RxIsMKIPresent, and SecurityIndicator. The administrator must configure TLS Enabled and SRTP Enabled flags on CallManager Admin User pages to receive the key materials. TLS link must be established between TSP and CTIManager. typedef struct CiscoTsp_MultiMediaEncryptionKeyInfo { DWORD AlgorithmID; DWORD TxKeyOffset; DWORD TxKeySize; DWORD RxKeyOffset; DWORD RxKeySize; DWORD TxSaltOffset; DWORD TxSaltSize; DWORD RxSaltOffset; DWORD RxSaltSize; DWORD TxIsMKIPresent; DWORD RxIsMKIPresent; DWORD SecurityIndicator; } CiscoTsp_MultiMediaEncryptionKeyInfo; Specifies the negotiated algorithm id.
