In the following table, x is the pattern number, y is the instruction number.
Both x and y need to be sequential. There are three categories of sound effect
patterns: callProg ( Call Progress Patterns ), ringer ( Ringer Patterns ) and misc
( Miscellaneous Patterns ).
Call Progress Patterns
The following table maps call progress patterns to their usage within the
phone.
Note Currently, patterns that use the sampled instruction are limited to the following
format: sampled followed by optional silence and optional branch back to the
beginning.
