This attribute specifies whether mu-law to A-law PCM conversion
is performed. aLawConversion only needs to be set to on when this
voice service is running on a DS1V or 1pDS1V FP and the
VoiceService at the remote end of the connection is running on an
E1V or 1pE1V FP using a software release prior to 5.0. If the
remote end software release is 5.0 or later, end to end negotiation
determines the compander law to use at each end of the connection.
In this case, the value of aLawConversion is ignored.
