SilenceDetectSensitivity PHONE port silence detection servers the purpose of
driving silence suppression in RTP transmission when the
phone Call terminates on SP1/2 or OBiTALK Service and
silence suppression is enabled.
This parameter is used to set a sensitivity level for OBi
silence detection algorithm. Available choices are:
Low (harder to detect silence)
Medium (suggested)
High (easier to detect silence) Medium
