mediamask |
DWORD |
0x001F |
mask |
Controls which functions are running or reserved when the call enters the connected (conversation) state. (The NOCC protocol enters this state immediately). Reserved indicates that the DSP MIPS are committed to the operation before the operation actually starts. The application must reserve DSP resources in advance by using this parameter for DTMF detection, silence detection, cleardown detection, and echo cancelation. See callctl.mediamask valid values. |

Bit field |
Controls echo canceler operation. Set the mode to one of the following: 0 = No echo cancelation. 1 = Use internal defaults for filter length and adaptation time based on board type. 2 = Use specified values. 3 = Ignore specified filterlength and adapttime values for adiModifyEchoCanceller only. Additional values can be formed by using the OR operation. See echocancel.mode valid values. |
