scalar r/w milliseconds Unsigned32

Voice DSP jitter buffer size in milliseconds. More
specifically, it refers to the amount of memory usage
that can store certain milliseconds of voice.
          
There are two types of jitter algorithms: static and
dynamic. Dynamic allows the jitter buffer to grow and
shrink as inter-arrival jitter changes. A static
jitter buffer does not.
          
When the jitterBufferType is dynamic, jitterBufferSize
is the initial buffer size the jitter buffer can grow
to.
          
Some examples of the voice connection types used for; 
Voice Over ATM (VoATM): pots-to-aal2, isdn-to-aal2, 
                        aal2-to-gr303, aal2-to-v52.
Voice Over IP  (VoIP) : sip-to-ds1, sip-to-gr303, 
                        sip-to-v52.
          
Valid range is 1 to 33 milliseconds for VoATM case.
          
Valid range is 1 to 100 milliseconds for VoIP case.
          
Default jitter buffer size is 10 milliseconds.
