The following functions are typically configured to share the same group of task processors: Call progress Voice record Voice playback Tone generation MF detection
For the typical configuration, DSP capacity is allotted under the assumption that every port is running at most one of these functions at any given time. If you concurrently execute a combination of these functions, you will likely exhaust the DSP capacity.
If call progress is opened with the NOCC protocol, call progress functions can be executed at any time. Otherwise, call progress can only be run after the call enters the connected state (see Chapter 6 for more information).
