Possible values
4 through 64
Explanation
For recording, this parameter specifies the amount of voice data that must
be recorded before the digital trunk adapter device driver can satisfy voice
data reads from the custom server.
For PlayVoiceFromHost, this parameter specifies the amount of voice data
buffer memory that must be used by the digital trunk adapter device driver
before it can start playing the voice down the line. This is important both
for the initial playing and any restart conditions, which might occur after
a device underrun error.
Note: When CA_Play_Voice_Stream() or CA_Play_Voice_Elements()
are used it is important that the voice data is written in integer multiples
of 4000 bytes or the voice data buffers used will be sparsely populated with
voice data.
For playing, this parameter is always rounded down to the nearest 4K boundary.
This parameter determines when the CA_Poll() subroutine returns on a recording
channel. See CA_Poll()in Blueworx Voice Response for AIX: Custom Servers.
