    Set the silence threshold used by the ANSWER_DETECT routine. Normally set
   to 5, this can be increased if a noisy phone line causes no silence to be
   detected resulting in an immediate voice detect during a ring or busy.
   The valid range is from 5 to 10. This function does not have to be set
   unless the ANSWER_DETECT routine returns an immediate voice detect and
   you suspect that the noise level on the phone line is greater than normal.  |
